Good day. I can't understand how the memory (Latch) is arranged and what the battery affects. The manuals are very uninformative. 1) iQ-F and iQ-R store the program in EEPROM. Without a battery, the program is not destroyed (as in previous series). Do I understand correctly? 2) In the memory settings, there is a Latch area. Registers retain their value when the power is turned off (I checked in practice), without a battery. How long will they be saved without power? 3) What changes in the operation of the Latch area if we install a battery? 4) Is the operation of the Latch area the same in iQ-F and iQ-R? 5) Thinking out loud. All registers by default work in RAM memory and when turned off, the Latch area is saved in EEPROM. Then when turned on, it restores the values ???

Hello, How do I move a string literal (e.g. 'stop') into an array of unsigned (or signed) words on an iQ-R PLC? The manual refers to the instruction $MOV, but it doesn't seem to exist for the iQ-R. I've tried the STRINGMOV (e.g., STRINGMOV(TRUE, 'stop', unsignedWordArray[0])), but I get an "Unable to convert type 'ANYSTRING_SINGLE' to type 'WORD' error. I would expect the following values after the operation: unsignedWordArray[0] = H7473 (0x73 = ASCII code for 's', 0x74 = ASCII code for 't') unsignedWordArray[1] = H706F (0x6F = ASCII code for 'o', 0x70 = ASCII code for 'p') unsignedWordArray[2] = H0000 (null characters) I tried searching the forum, but I get an error when I try to search. Thanks,

Hi, has anyone tried to get a Mitsubishi iQ-R to communicate with the Keyence IV3 series cameras over Ethernet/IP? There are videos about how to use the IV3 with Allen-Bradley (Rockwell) PLCs but Rockwell's implementation of EIP is completely different from Mitsubishi's implementation. I am using an existing system with the RJ71EIP91, I have the IV3 EDS file added to the Ethernet/IP Configuration Toll for RJ71EIP91 software, I know I need to add the IV3, set the IP address and connection number. But how do I access the data, and send the trigger for the IV3? The instruction videos for Allen-Bradley uses the I/O tree to create tags and pre-made AOI's to create the logic to do all of the communication work in the PLC code, which is a process that I am familiar with. However, none of that is relevant to the Mitsubishi PLCs. I figure I have to use somethning like Uxx\Gxxxxxxx in my logic to access the data for the IV3 from the RJ71EIP91 module but not sure how to get that to and from the actual IV3. Does anyone have any ideas? (sorry my initial post was blank, accidentally prematurely posted).

Hi All, I need to start PLC Data Logging using an SD card in the CPU module for an iQ-R PLC. I have not attempted this kind of logging before and I was wondering about any restrictions on the type of SD cards that can be used. The documentation I have found says "SD/SDHC memory card: 32Gb maximum". Does anyone know why can't I use a 64 GB SD card ? (maybe due to addressing limitations?) Also, when I look for SD cards, I see different speeds of data transfer such as 120 MB/s or 100 MB/s and I was wondering if there is any difference as far as the logging is concerned. Does anyone know if there are any other restrictions, brands that don't work? Useful tips? Cheers

Hello, I am trying to do something tricky today by simulating an IQ-R plc(R08CPU) in gx works 3, and to make it connect to Fernhill SCADA as well. All done on the same PC. My goal is to see that I can make the IQ-R series work with Fernhill as that is also a question I want to solve before buying the PLC and I was hoping I could use the simulation for this. I have tried searching if this is something that will work at all and so far I have not found anything... It feels like it is a very special case to have both the simulation and the SCADA on the same pc for one, second is that I don't know how the simulated PLC's IP address will behave, I cannot ping it for instance. The first step of my issue is, My simulated PLC has an IP address. In my mind I should be able to ping this address on my PC, which I cannot. If I cannot use the simulated PLC's IP address, I will have a hard time connecting it to the Fernhill SCADA. Second step/question is, will the Fernhill SCADA be able to work with the simulated PLC? help is appreciated!

Hello everyone, I am studying Mitsubishi R-Series PLC with GXwork3. I don't really understand communication using CC-Link. Below I have the module configuration that I use. My hope is that the Digital operation value of the AI module is stored at addresses D0-D32. and I sent AO to address D100-D132. can someone guide me to give me an example of how to set parameters and create a program. thanks you

is there is a function built in to convert chars like "XYZ.." to hex and vice versa ?? I am new to the iQ-R series and trying to figure it out, the GX-Works version that I am using is 1.038Q any help would be appreciated

Hi everyone. I need help with iQ-R system. Is it possible to connect an additional expansion bus to an existing system without powering down? Also, can I install new I/O module (RX40C4) to an existing system at hot state (like a hot swap)?

Hello, I want to know, if it is worthwhile to transfer from Q series to iQ-R? Currently our equipment is using Q series, which ss a vacuum coating equipment with about 10 power instruments, 20 gas controllers, and pumps and so on. As for the analog and X, Y points, Q is quite capable. I can not see any advantage to switch to iQ-R, but some people want to. So I want to know, 1. will Q be outdated in the near future? 2. will use iQ-R cost much more than Q? including peripheral units. 3. has iQ-R really been widely adopted? 4. thoug iQ-R may be powerful, I think use multiple middle size CPU's can be more advantageous, is this right? Many thanks in advance. Ting

I am working with iQ-R PLC projects, and a lot of documentation is involved. I am trying to find a way to automate that, but I don't know how to get information out of the PLC project file in a way that I can parse and use to create the documentation. (Like tags, UDTs, AOIs, etc..). I was thinking they'd have something comparable to how with Allen-Bradley PLCs you can export to an xml file, but I have found nothing like that. Initially I just want to export to get info out of the project, but it would be nice to also be able to import to a project so I could programmatically create PLC projects. From what I've found, apparently EZSocket is MELCO's collection of APIs for stuff like this (That description could be wrong), but I've been unable to find actual documentation that would help in using it for this. Thanks, Joshua -
Hi All, Have recently embarked on a project that has required me to change over to GX Works 3 in order to link an IQ-R120PCPU to a Citect 2018 SCADA package . In days gone by under IEC Developer and GX Works 2 it was quite easy to establish communications between the programming package running in simulation mode and a running Citect system using the MXCOMP driver via MX Components to perform offline testing. Can't seem to find a way to get it to work under GX Works 3 though, has anyone tried a similar setup Simulated logic in GX Works 3 is running fine and can modify the IO from inside MX Components "PLC Monitor Utility" program so there is no issues there, just cant get Citect to communicate. MX Component comm's has also been proven reading/writing variable to an excel sheet with GX Works 3 in simulation mode also. Attached are the files for getting GX Works 2 up and communicating to Citect 2018 via the same method i am trying to get working in GX Works 3 in case anyone ever needs to use that method. Any help would be appreciated. GXWORKS 2 & CITECT 2018.zip -
Hello. I am trying to develop some structured text POUs in Gx Works3 (function or function block) which are to do some calculations over array. Say it will be crc32. So I need to pass an array to such POU. It would be very nice if POU could work with array of arbitrary size. I have found some built-in functions which take arrays and their respective arguments have type of ANY16. But when try to declare an input variable of type ANY16 and use it with indexer I get the compile error that it is not an array. Also I tried to declare input variable as an array of the size of one element. It compiles but does not work. As I understand, there is an index register that can help solving such problem but I have no idea of how to apply it to arbitrary input parameter. Does anybody know how to iterate over an array input parameter and how to declare it properly?

Hi, I have R04CPU (iQ-R series) on one side and on the other side is QJ71MT91 (modbus tcp/ip module). Is it possible to make communication between them (QJ71MT91 is master and R04CPU is slave)? iQ-R series doesn't have Modbus TCP/IP module, but is it possible to set modbus tcp/ip on built-in ethernet port of R04CPU, and how? Best regards Luka

Hi Has anyone got any real life experience with the new Mitsubishi iQ-R series? I have been assigned a major capital project to replace our old ageing DCS system. Our current PLC backbone is about 40x Q2ASHCPU, 10x Q06UDEHCPU and about 2xA2SCPU all linked up via Melsecnet/10 network with communication links into the DCS system via Modbus RTU utilising the QJ71MB91 modbus card. Due to the nature of my companies process and the limitations on plant downtime it is estimated this project could take up to 5 years to complete, with this in mind I am wanting to install a system that will not be obsolete (or unsupported) in a few years, hence, I am very interested in the new iQ-R series with it being Mitsubishi's latest and greatest. However, recent communications with my local Mitsi rep is not filling me with confidence that the iQ-R series is not as well supported/developed as the Q series. A major requirement during the development stages of this project is the new ability of the new processors to be able to talk to the old DCS up until a point where the DCS nodes will be completed removed and replaced with a modern SCADA package. Hence, the requirement of a Modbus Slave card for the iQ-R (i.e. a QJ71MB91 equivalent) which I am told is in development, but has no fixed timescales. Previous experience with Mitsubishi developments of cards is normally years not months. Any information anyone can provide on their experience of the iQ-R series would be greatly appreciated and if anyone knows if a Modbus Slave card is in development that would be useful. I realise i could utilise the Q series extension rack with a iQ-R processor but this is not the route i want to go down. Thanks for any help and apologises for the war and peace. Cheers Matt

Hi Im working with an iQ-R CPU wich controls 6 conveyors with a CC-Link IE Field Network, the CC-Link module is a RJ71EN71. Each conveyor has a remote I/O (NZ2GF2B1-16TE Digital outputs main module with a NZ2EX2B1-16D extension for Digital Inputs). The communication in the CC - Link IE Field diagnostic appears to be OK, but I can´t send or receive IO signals from the Batch Monitor of Gx Works 3. Thanks for your attention!
