AB7006-B

Hi,
We are using Ab7006 to gather data from RS485 (only data is read) and sent to Control logix on controlnet.
After scheduling the network we are seeing error in conrollogix as below:
code 16#0109 connection request error. Invalid connection size Tag Anybus_1_L1UPS:I.

It looks like the Input/Output sizes set in the Anybus do not match what you have configured in your PLC. Make sure that you have downloaded any changes in the sizes to both devices.

Can you please correct if our understanding is correct to set various parameter in configuration manager our application is as below:

We are only reading data from 2 nos. of UPS on RS485 with data size of 52 bytes for each ups.

What should be value of IO sizes on Fieldbus Tab should this be set to automatic or to user defined and value of “IO size in” set to “52+52” = 104.

And on CLX end:

Input Assembly Instance set to 100 and size set to 104 (8 bit)
Output Assembly Instance set to 150 and size set to 0 (8 bit)
Configuration Assembly Instance set to 1 and size set to 0 (8 bit)

And then schedule the networx.

I would recommend using Automatic.

What version of RSLogix are you using?

Have you tried importing the EDS file and then “Add Module” to the tree? You may not be able to use an output size of 0 without the EDS file (Using Generic IO device).

Please use Automatic IO size in Fieldbus tab.

Hi,

We are using V24 of CLX.

By creating dummy node in sub network and after assigning output to that node and setting io sizes as per our requirement we were able to schedule the network.

OK good. FYI, you can also use a trigger byte for a dummy output, or you could import the EDS file instead of using a generic IO device and you won’t need to have any output.
