Configuring I/O

[rickplc]

I need help configuring the I/O for an A2SH series PLC. I know how to find where to do it (using GX Developer 8.25) Parameter/PLC Parameters/ I/O. The cards in the physical slots are: Slot (0), A1SJ71E71N (Ehernet Card), Slot (1) A1SG60, Slot (2) A1SX42, Slot (3) A1SY42, Slot (4) A1SY42, Slot (5) A1SJ71PT32, Slot (6) A1SJ71PT32, Slot (7) Empty. I have tried different variations but have either achieved the PLC to fault or not recognize a discrete input address while in Run Mode and Online Monitor. Please help with as much detail as possible even if I need to change something in the way I use the Write to the PLC function. email]rick_rcc@hotmail.com

Hi rick, Your I/O should be set up as the following: Slot 0 - Special Unit - 32 points (X/Y 000 - X/Y 01F) Slot 1 - Empty - 32 points (X/Y 020 - X/Y 03F) Slot 2 - Input - 64 points (X040 - X07F) Slot 3 - Output - 64 points (Y080-Y0BF) Slot 4 - Output - 64 points (Y0CO - Y0FF) Slot 5 - Special Unit - 48 points (X/Y 100 - X/Y 12F) Slot 6 - Special Unit - 48 points (X/Y 130 - X/Y 15F) Slot 7 - Empty - 32 points (X160 - X17F) Let me know if this is what you are after? Note: The A1SJ71PT32 use 48 points in extension mode and 32 point in i/o dedicated mode. Regards, WayneS

Thanks Wayne, I see where I made a couple of errors in my configuration attempts. I have another question that I have not been able to find in the pdf manuals. I have noted above the cards there is a switch that has a setting that can be moved to L or F. What is their function and where should they be set?

[Crossbow]

Not sure what you mean by above the cards. Where is this switch? On which card? Some AnSH modules have DIP switches to set some configuration data. You'll need to look those settings up in the manual for that particular module. If it's on the 64 pt discrete modules, that switch would be L And R, for the left half and right half. The module only has 32 LEDs, and it has 64 points of I/O. So in the L position it shows the first 32 (the left connector on the card) and in the R position the second 32 points (right connector on card).

On the 64 Input Output modules there is a switch called F and L, and your correct about the functionality of this switch. The left side LED will display the first half devices (X00..X1F or Y00..Y1F). On the other modules there is no such a switch present. Be carefull to connect these I/O modules, because the are of the sink type. And goodluck with configuring the mininet (A1SJ7132PT module), it is not so easy.

Thanks to all. Your information is very helpful. The pdf manuals did not give me lot of information on the mininet. I did deduce that the device looked like they communicated with muliplexer/demuliplexer switch. Can anyone suggest a document to read about this device?

[FNMdeJong]

Indide the manual section 5 there is a complete example for setting up the communications. Look at the BFM area's then you notice that each remote device has its own area inside the memory. And each request for transmit has its own dedicated I/O. p.s. When using a QnA CPU you can do it by parameters, much easier than using an A CPU.

Thanks Sparky, Can you provide with pdf file number you are referring to? I want to make sure I'm usig the most detailed document. Thanks Sparky, Can you provide with pdf file number you are referring to? I want to make sure I'm usig the most detailed document.

are we talking about A1SJ71PT32 manuals? IB(NA)66492-A 154.60KB PDF A1SJ71PT32S3 A1SJ71T32S3Melsecnet Minis3 Master Module Users Manual (Hardware) IB(NA)66565-F 5.39MB PDF AJ71PT32S3 AJ71T32S3 A1SJ71PT32S3 A1SJ71T32S3 Melsecnet Minis 3 Master Module Users Manual

[rickplc]

Yes, these manuals contain more information than I had. I definitely know I will have more questions concerning this issue. I hope I can request additional information from everyone. Thank you again to each of you. Rick

just look under download section of www.meau.com and you will find just about anything (PDFs, DWGs, selection guides, some programming sample like for E-Series HMIs etc.)

I'll check the site that you reecommended. Setting up the communications with the two cards is (I hope) my last big hurdle. I've been looking at section 5 and I'm in need of help understanding. Below is what I have as far as hardware and their station numbers (set on AX41C and AY13C). What would I need as far as programming to read and write to the I/Os for both cards?

don't know for mini, never used it but i guess setup will be similar to melsecnet, ie. make sure to have all manuals (every card) and confirm that combination of cpu and special card(s) is supported, go to parameters,networking parameters and assign range. on the hardware side make sure everything is wired correctly (topology, terminations...) and nodes are assigned properly (dip switches or rotary switches for node address, sink/source selection, clear or hold on comm loss etc.). when trying something new it is a good idea to start small. make temporary bench setup and add just one slave. once it works add another etc until you are sure it works as espected. don't just connect 30 slaves and expect to then figure out proper settings. note that output cards have separate terminals for module to function (communicate) which will have to be "permanent power", and outputs power which may be interrupted by safety circuit for example.

See page 5.11 for an program example of the manual No 81997 : A1SJ71PT32-S3 User Manual. There is a complete example with initialisation and read and write to a station. In this example station 1 is written and read form. Transfer section is from BFM H640 and receive section from BFM H44C. See also that the communication area H640 is changed by reading and writing, depending on the command and the BFM address to refresh. For remote IO Stations see the example on page 5.5.

Is there anyone that has experience working with the mininet consisting of the hardware I have furnished with previous posts. I still can't resolve the communication setup with the 2 cards. The only manual I have showing an example is IB_NA_66565-F. Please help any way you can.

[FNMdeJong]

You're configuration of slaves is correct. The master station is always No. 0 and each slave takes up 8 bits. So if you have more IO's on a slave you need more stations reserve for that slave. You are not allowed to skip station numbers. Inside your PLC Master configuration use the Mininet master stations as 32 IO. In this configuration just use the IO dedicated mode to communicate. No need for registers to communicate (Extended mode). Make sure you have the wiring correct. See the attached wiring example. For a overview of the BFM reading and writing areas see the attached file Read_BFM and Write BFM. For a example project of the Mininet with only one slave see also the attached file.

There is progress! I now have the Run, RD and SD LED’s on the first mininet card lit. First time the communications card did not fault the PLC when the communications program was active. The change that I made most recent is to the argument that controls the number of stations. I based the total on the number of stations, 14 units x 4 (4 eight bit words per card). I still cannot read an Input such as X209. Questions: Referring to document I B_NA_66565-F.pdf page 5-5 and 5-6 shows a communications program example. What I need help with are the individual arguments in the instructions. I would like to know their function as well how they are determined. Such as: The H argument specs., the beginning address for the card? The K0 argument specs.? The K4 or last I believe specs. the word length? These reference lines 0, 23 and 34 Is there a way I can upload my proram for review?

[FNMdeJong]

What instruction you refering to?? Is it a from and to instruction. You have to read from the buffermemory, but first you have to startup the communications. For the from and to instruction see the programming manual. [TO <module number> <BFM adress to write> <source to write> <Number of write actions>] Module number is the starting IO number minus the last digit. If you select BFM adres K10 and source D0 and number to write is 2 then BFM K10 and K11 will be written by resp. D0 and D1. For the FROM instruction the same arguments are there. [FROM <Module Number> <BFM adress to read> <Destination to write> <Number of reads>]

Good Morning, I solved the communications program last week thanks to everyone's help. Both cards are communicating and I have proven to myself that I can read at least one Input or turn on an output to each station associated with the 2 cards. One thing that does concern me is when I started communications for the Mininet card in slot 6 I would note what appeared as flashing contact closures from the inputs (maintained contacts). Back ground, I wrote what I called a test program that started communications for the two cards and had inputs and outputs addressed that I could manipulate from all the AX41C and AY51C stations. I am assuming this to be electrical noise. I proceeded to modify my program by placing a counter branched around the output that is being driven by the remote inputs that are flashing even though the switched inputs are either closed or open. The counters only indicated valid contact (input) changes and did not count the flashes. I've looked over the manuals and checked for the oblivious. Can anyone make any suggestions even elementary ones? Thanks again! quote name='rickplc' date='Aug 22 2006, 07:44 PM' post='38857'] There is progress!
