PLC-5 30, 1771-IFE/C manual configuration

Guys, I am having problems setting up an analog in module. The PLC is existing, and has two 16 slot chassis. Single slot addressing. My new module will be in rack 3 group 2.

The remote chassis contains a 1771-ASB.

I cannot access the IO configuration dialog, when I do, it does not appear that this was ever set up. Is this possible?
The IO config dialog box come up with the scanner radio button selected.

I thought I could add my new module without using this dialog, but I have not done this a over 8 years.

Here is where I am. I have the BTR and BTW set up with the enable bits and the first scan bit for the BTW, like the manual says. I will be differential 4-20ma. My data lengths in my BT instructions are set to 22 for the BTR and 39 for the BTW. These are probably more than I need. Let me know if they must change.

My data in the config N: file is set to 500H for word 3 of the config word, and my min & max range registers are set to 0 & 4095 respectively.

• I am not sure if my BTR and BTW have the appropriate Rack/Group/Slot settings. They are set to 3,2,0 which coorresponds to the location that the module is installed. was this supposed to be the remote IO adapter RGS or the actual card RGS settings like I have?

• One odd thing I saw, is that the BT control file records do not have any data in them. Is this normal?

• I also have the ER coil active on the BTW, and no status bits set in the status word of my data file for the BTR.

Any help would be appreciated.

Yes, PLC5s do not require I/O configuration. Its for documentation only, very helpful if it's there though.

The word length of 22 and 39 are correct.

What slot is the module in?
Can you post the .RSP file ( zip it first)?

Attached should be the file, hope I did that correctly....

Using your file I added the card to the I/O configuration. That is the easy way to do it. See
picture below.
You need to add the remote chassis to the I/O configuration then add the module to the chassis, it will ask you if the BTR/BTW exists just say yes.

Is the module in the slot shown in the picture? If not then you will need to change the Rack/Group/Module settings.

Also check and double check the jumpers on the card to make sure they are where you want them to be.

Also the rogram (file ) you posted shows 3 remote I/O racks? Which one is the new card in?

What is the size of the chassis with the processor and the size of the remote I/O chassis?

Mickey,
First let me thank you for your help. I ended up setting up the IO config for both chassis, they will need that, and it was not that painful, I noticed the PLC5 software recognizes the points associated by address.

I configured the analog module with the config utility, and I deleted my BT instructions, and let it re-create them, as well as overwrite the data. It made the same data settings that I had, but it also properly set up the BT records, which I did not do.

I still have an error bit on the BTW, but no error bits in the BTR status register. Originally the jumpers were not set, and I knew they would need to be, so I took care of that, but still the error bit. Furthermore I set a value in the first analog data register, and it did not get overwritten.

I will be back out there to work on it some more.

PS, could the Rack 4 you asked about be a panelview device? The existing program has a bunch of panelview BT instructions that refer to Rack 4.

Forgot to mention that I did toggle the first scan bit to initiate the BTW write to the module for setting it up.

Thanks again.

Yes, if your PV supports RIO protocol.

Are you sure about the slot # to card is in. Remember the first slot in PLC5 chassis's has no number, it's for a processor or a RIO adapter. Sorry if this sounds basic, but thought I would mention it anyway.

Tell us how you set up the jumpers and post your new program and maybe someone can spot something.

BTW, the program you sent is password protected.
