Hello, I am new to this forum. I have been finding great information here and elsewhere, but so far not exactly what I am looking for. Has anyone used a Micrologix PLC to read messages from a large number of other micrologix PLCs? I have used this instruction successfully with serial and Ethernet communication but only with up to 4 or 5 other controllers. One constraint I have already run into is the max size for data words in this processor of 10k. I was able to reduce the number of words I was reading and at this point am using about 2k for the interger files to be populated. There are 24 integer files with 80 elements each. The other issue is with the amount of data each RI file uses of 24 elements. The idea in this application - which is a water utility - is to have all data exist at all sites. I was originally going to use the Maple Systems CMT3261Xv2 HMI which is installed at each, to poll all the sites, but I don't have a high degree of confidence in its ability to do this based on bench testing I have done. I will keep working with Maple tech support to figure that out. But I also need some of the data traded between PLCs for other reasons, so having all the data in the PLC registers is a bette solution if I can make it work. Since each PLC needs to have data from each of the other PLCs, having a master read and write to all the sites would overwhelm the processor in terms of data used (24sites x 24 MSG instructions per site x 24 words per MSG instruction = 14k words). Also, I don't want to write all that code, since with the ML1400 I don't believe there is a way to use indexing on the MSG instruction. (I could use a Compactlogix as the Master, but presently don't have that in the budget. Also, by using another ML1400, if the master PLC goes down for some reason, any other PLC could become the master. So my solution is to have the master read the 80 words from all 24 slaves into each apointed integer file and then have each "slave" read data from the master for each of those integer files. That will use 80x24 words for the integer files and 24x24 words for the MSG instructions for a total of 3k words used. The rest of the application uses little data at each site. But by having each slave read 24 data files from the master, I can just copy and paste the routine into each slave. I have already created a template for these sites, so I would just need to include the proper messaging routine. I have 10 ML1400 PLCs for bench testing, but I am worried that having all 24 in action might create problems I am not forseeing. For example, is it possible that having 24 processors read from one processor in an unregulated manner would cause data collisions? I know it is Ethernet and that is less of an issue, but I just don't know. I also don't know how I would regulate it. In the past I've used timers, but I don't want to slow things down since there are so many messages. I also don't know the best logic to use for the messaging. In the past, I have used cascading logic in serial communication where after one message is done or errors it triggers the next message and the last message triggers the first. Then I had a watchdog timer to restart the routine if it got hung up for some reason. I have seen many examples where one rung has the MSG instruction and the next rung has an unlatch instruction triggered by DN or ER from the MSG instruction. Presumably when the first 4 buffers fill all the rest would be put in the que, but again, I am not sure what unexpeted consequences would occur with that many messages. I don't know what is the best practice. I have yet to find examples of this online or with Rockwell. The physical layer is high-speed internet using a dedicated LAN for the application. We are using fiber for about half the connections and Cambium gigabit radios or 900mHz radios for the others where the lowest throughput is probably 1mbs, but most connections are over 100mbs. The plan is to be able to monitor and program each PLC and HMI remotely once the system is operational. Thank you in advance for your consideration and expertise. -

Hi guys, my site uses mainly Mitsi PLC's & HMI's so not familiar with AllenBradley but i have two Micrologixe 1200 PLC's connected to Panelview 300 HMI's. The machines are twenty plus years old and now both HMI's are barely legible as the screens are so dim. I want to upgrade the HMI's as they are obsolete but my problem is, the program within the PLC is Password Protected and i cannot read, upload or download to the PLC. The original manufacturer has been taken over some years ago and no-one knows the password. They have sent me an old program that could possibly work which is not password protected, but i cannot download it to the PLC without the original Password. Can anyone help me?

Uploaded a program from a micrologix 1400, I added an integer data file. Went to download it, and the processor types were different. I suppose I am just going to change it to match what is on the machine, but why did this happen? The controller was password protected. so maybe it did not get the processor info for some reason. Even when online with the processor, it reads incorrect.

Good day everyone, First post here so hopefully I'm not violating community guidelines in anyway. I've got a system that has some 50 odd Micrologix 1100 and 1400 in use and I'm currently working on setting up an auto timesync for all of them using just 1 of the PLCs that will be my master time PLC. So far I've put together the logic for all the message instructions with the corresponding IP of the slave devices. I'm running. Into an issue with not being able to terminate/break the message connection on a PLC that I have already synced. Is this even possible to do on the ML1100. Once I get to 16-17 messages DN it starts to ER and will not complete any further messages. What I have is a message instruction ladder with a timed trigger to activate a MSG and write the RTC data then time down and connect and write to the next and so on. When it triggers the message instruction of one PLC it also fires an OTE to trigger the BK of the previous message instruction. However it doesn't seem to be actually cutting the message connection and holds it persistent until a power cycle/download event. -
Hello everyone! I would like to connect a Micrologix 1100 with Citect 7.5 via ABMLXEIP (updated to latest version). I tried everything and it is still not working. The Citect and the PLC are on the same subnet and the ping works fine. All the configuration is done as the manual says (I attach the pictures). I have one NIC card and is connected to the PLC. The role is setted to “Server and Control Client”. The kernel has this error: [ERROR] [CORE] [0x07fc] [IOServer] [(GLOBAL)] [ErrorLog()][errlog.cpp] [266 ] Error: Channel offline, cannot talk CINIT 0015 PORT1_BOARD1 IODev_1100 Error_in_CMD-2 16 Generic 000021 Driver 00000020 (0x00000014) Any help would be much appreciated! Thanks, Gustavo.

Hi all, I have my own driver to communicate with a MicroLogix 1400. Please refer to the attached screenshot from Wireshark. 10.10.21.10 is my driver's host, and 192.168.1.192 is the ML1400. The startup sequence to establish a connection & session with the PLC is correct I believe: - In the grey highlight, client requests a connection to .192 via SYN and this is ack'd - A session is registered, and forward open is successful - There's a lot of stuff in green simply because I've also got an HTTP browser session open to the PLC to monitor its session table - In between, spaced 8 seconds apart, are my two attempts to keep the connection alive by sending a List Identity request (as a ping, if you like). These are highlighted in pale blue. - However, 16.5 seconds from the start of the grey highlight, and 16.4 seconds after sequence=115 ack=99, the controller sends back a [RST, ACK] and a callback from my socket code tells me that the session has been dropped. The connection timeout for the PLC is configured as either 30 or 60 seconds, so I don't see how that's relevant here when the reset is happening only 17 seconds after it was established ? However, presumably the PLC doesn't see the application-level "List Identity" request as a valid means of keeping the connection alive. What is the correct mechanism to use that the PLC will accept as a keep-alive ?

Hi there, As a software engineer, but a newbie to the Allen-Bradley world, sorry if this question doesn't make sense. I'm enhancing an existing driver by trying to add the ability to read/write structured and array data types - rather than just the elementary data types it supports right now. This following question is only in the context of SLC/500 & MicroLogix 1400. And I'm currently working on a Counter as a test case, but any solution obviously needs to take into account other structured (and array) data types. One of the requirements is that the user should be able to select a specific atomic item within a parent structure/array that they want to read/write. So, using the Counter as an example, they might want to define a field which holds just the value of the accumulator. I know that I can achieve this with a CIP command. I specify file type 87 for counter, file number as 5 (my test example happens to be the standard C5 data file of counters), and element is 0 (for the first counter in C5). Bit number is irrelevant so remains as zero. I ask CIP to return me 2 bytes of data (to hold just the accumulator word). Finally, I tell CIP that I want sub-element 2 (because the accumulator is Word 2 of the whole structure). Sure enough, the CIP response gives me exactly the 2-byte accumulator value I was expecting, nothing more, nothing less. Success. My question is this: I knew I had to specify the sub-element as 2; this happens to work for a Counter because of the way it is structured as 3 words. However, it implies that the value I specify for sub-element is ALWAYS measured in units of 16-bit words. Is this a universal truth (i.e. works for other structured types too ?), or does the size of a sub-element depend on other factors, such as the file type ? Thank you in anticipation. -
I thought only PLC5's had EEPROM, but I was told MicroLogix PLC's also have an EEPROM that need to be burned to... What are all the PLC's that have EEPROM and require an EEPROM burn to prevent the program from being wiped in a power cycle?

hmi HMI G3 not working using Crimson 2.0
DBOVF posted a topic in Allen Bradley / Rockwell Automation
I know nothing about HMI's or Crimson software. I'm in I.T. and we had to change the third octet in the IP address and gateway on all devices at our warehouse. I extracted the file on one HMI, changed the ethernet info, and clicked send. That HMI that runs a carpet machine works perfectly. I went to the second carpet machine. Extracted the file changed it's ethernet info, clicked send. It came back with all ---- (dash's) instead of zeros, the carpet machine won't work. I kept messing with the file trying different things, and inadvertently saved over the original extracted file!!!!! So I thought I'd extract the file from the working carpet machine and loaded it on the second carpet machine. I get the same issue, all ---- (dash's) on the HMI and you push any of the buttons on the front of the HMI and nothing works. These are Allen Bradley MicroLogix 1500 running Crimson 2.0 HELP I don't know how to resolve this issue. I would have thought both HMI's would have been the same! HMI all dashes.eml HMI all dashes2.eml

I have a micrologix 1100 PLC as well as a weintek HMI all connected through a network switch for them to communicate between each other, however I'm having an issue where the Micrologix Controller will not retain its IP address once I set it through Allen Bradleys BootP tool. I can set it through the tool and then go into RSlogix 500 and communicate with it and all that, but once the controller is turned off the IP address goes back to its factory setting of not showing an IP at all. Any suggestions/ ideas as to what I'm doing wrong?

Have a micrologix 1200R 1762-L40BWAR. If anyone could help with providing the following information: Need a communication port with single receptacle that will mount through the door of electrical enclosure and then the communication cable (6 to 10') that will go from the com. port to the micrologix. Thanks -
Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. -
Hi my problem may have a simple solution but i cant work it out. I need to use the Divide function but it wont let me use a decimal point in either Source A or Source B. Is there a way to use a decimal point in Logix 500 Math instructions? Im using an AB Micrologix 1400 PLC. Can you only use math instructions with whole numbers? is there a way around this? Thanks James -

Hello :I'm the creator of an Android HMI app, I recently added Ethernet/IP connectivity with MicroLogix and SLC AB PLCs, but I have only been able to test it with a MicroLogix 1100.I'm really not sure if it works with SLC or with other MicroLogix models.If someone could try it, I would appreciate it. To access the test, from the Android device, open this https://play.google.com/apps/testing/com.suppanel.suppanel on the web browser and install the Beta version.On the application you have to open the "EIP MicroLogic SLC Test" panel that contains some instructions. Thank you very much !

Good evening(here at least), I am working on a senior design project that requires the use of a PLC. Due to budget we've had to settle for an older Micrologix 1000 from Allen Bradley. I've managed to get the software running and connect with the programming port. The problem I have right now is trying to decipher how I would connect a load cell(Such that it causes a condition change at a certain weight). Ideally I would want a load cell amplifier connected to an analog input, but I don't think the 1000 has support for that. Would it be possible to use something like the HX711 amplifier(digital output) to be read on one of the input pins of the micrologix? I wanna say the pins don't read a pulse modulated input and I can't seem to register for the AB knowledgebase as the site gives me a web error. I'd appreciate any feedback. Thanks in advance.

Hello, As the title indicates, we have a micrologix 1400 that has been installed for a long time. Recently it faulted out on 71h and was in Remote Mode. Do these PLCs revert to Remote Mode when in a fault condition? We placed it back in Run Mode and everything worked fine, but how did it get to Remote Mode in the first place? Thanks, J -
I have a "paddle wheel" style flow meter that I am trying to wire to my Micrologix 1400. It is a three wire device and there is a tag on it that says it can run at 6-36VDC. So, naturally, I thought to wire this to one of the HSC inputs of the Micrologix directly. I hooked the ( + ) on the meter to 24V, ( - ) on the meter to common, signal to the oscilloscope, and ground on the scope went to common. I see a small 60Hz sine wave @ like 5mv when the wheel is not turning. When the wheel is turning I get a small square wave but in the same mV range. It is not a nice smooth square wave either its all jumbled up with the 60Hz sine wave. I hooked this thing up to a transmitter and scoped the signal and ( - ) in parallel with the wheel - I get a nice smooth square wave signal when the wheel turns. It is only at 4.5V though. My questions are? Why does't the paddle wheel give me what I am expecting directly? Also, what is the voltage range on the pulse that a micrologix will see? I am assuming that it will not count a wave with a 4.8V amplitude.... Thanks for your help in advanced! neech -
Hey guys, I am working on an application that tracks irregularly spaced PET bottles on a conveyor line and then blows them into boxes waiting on the side of the conveyor. I believe I have working logic, but I am having issues with the encoder at operating conveyor speeds. I believe the best logic for my project is to use a photoeye to detect the presence of a bottle (a one-shot makes sure it is only detected once), and then "store" the "presence" of the bottle in a binary file using an encoder pulse to trigger a BSL function. Using this logic, the bits in the file are analogous to a real, physical location on the conveyor, and I can just monitor specific addresses in the file where my real-world air nozzles are located. My current problem is that as my conveyor speeds increase, the PLC begins to miss pulses from the encoder. During my initial set-up, I took data at very slow speeds to experimentally determine how many pulses were between the photoeye and each air valve, but when I run at full speed, I only detect about 70% of the pulses detected at slow speeds. Not good. Althought the "skipped pulses" seem to be proportional to the detected pulses at slow speeds. I am using an encoder that only runs at 60ppr, so I would think that my PLC (MicroLogix 1200) can handle this...I did the math before I purchased the encoder and thought I found the pulses to be infrequent enough that the PLC wouldn't miss any. My 2 trains of thought: 1) I need to use an interrupt for each encoder pulse since they occur so quickly (utilizing an EII), which I am not fluent in. I can find instructions to intitially configure the EII file, but I am unsure of how you are supposed to correctly set up the ladder logic to utilize the interrupt. 2) There is an electrical issue. The encoder I bought uses pull-up resistors. The resistor value I selected only drops the detected voltage to 14V from 24V. Is it possible that the encoder does not spend enough time in the "off" state at high speeds because of this high voltage value? OR does the usage of a resistor introduce a time-lag into the system which further complicates the issue? Any help would be appreciated, Thanks!

Hello all, I am still fairly new to this forum and PLC's in general. I am trying to connect a EA9 touch panel via Ethernet to an Allen Bradley Micro Logix 1400 PLC. I am using Ethernet over serial because I need the serial connection to program while using the touch panel. I have given the Panel the IP Address 192.168.1.20 with a subnet mask 255.255.255.0 and I have given the PLC the IP address 192.168.1.10 with a subnet mask 255.255.255.0. The panel is not communicating with the PLC and I have very little knowledge on the subject, anyone's help would be greatly appreciated. The picture on the top is from the PLC and the picture on the bottom is from the C-More program for the panel.
