How can I change the “Area” for input and output of the AB7318? Rockwell calls these “Instances” rather than “Areas” but the appear to be the same thing. I have the configuration software, but I can’t find settings for input and output areas. I couldn’t find anything in the manual, either.

I have a config file that shows areas 62 and 2. I was expecting 100 and 150, per Rockwell defaults. I have attached some sample config files.

Hello Cody,

Thanks for reaching out regarding this issue.

I would need to .cfg file to see the configuration. Based off of your description it sounds like you are mixing up the instance with the instance size. You would need if adding the device as a generic data device. See the following two application notes for a detailed explanation for adding the devices in studio 5000.

The cfg (in this case hcg) files are attached. The areas/instances are 106, 2, 1024, 62, 2, and 1024. The sizes are 509, 505, 0, 509, 505, and 0.

Hi Cody,

Ah sorry about that I was thinking this was a communicator that uses .cfg files.
Your setup is using the following:
input instance: 100 size:106 bytes
output instance: 150 size: 2 bytes
configuration instance 1 size: 0 bytes

Keep in mind this is in bytes, you will need to convert the bytes over to the data type you are using in the PLC.

If you check the screen shots, you can see that the instances (areas) don’t match what you listed below. I can’t figure out how the hcg files were configured to use different ones.

Hi Cody, The instance is always going to be 100 and 150. You will only see the sizes change.
The numbers in parenthesis is showing the max size that area can be configured.

I did skip one device so you have one using:
input instance: 100 size:106 bytes
output instance: 150 size: 2 bytes
configuration instance 1 size: 0 bytes
The other is:
input instance: 100 size:62bytes
output instance: 150 size: 2 bytes
configuration instance 1 size: 0 bytes

Best regards,

OK. That makes sense. I counted the number of bytes that each one uses, and it works out.
