AB7072-B Transaction Errors

Hello,

I am setting up some AB7072-B modules. I can see modbus data on the output of the Anybus most of it looks correct. On the front of the device the Subnet status LED is flashing green, then red indicating a transaction error. I will attach logs of both devices and their configuration. I do not know what the transaction errors are.

Error Log AB 4-6.txt (26.6 KB)

What are the serial devices? Do you have a manual you can share with us?

Have you installed a termination resistor (see page 128 in user manual)?

Does the data you are seeing in the logs look at all like what you are expecting?

Hey Kyle,

  • I have six compressors that communicate to my Gateways over CAN bus.

  • The Gateways translate CAN to RS485 Serial.

  • I have two Gateways with a Anybus Translator connected to each. The first Gateway/Anybus reads nodes 1-3, the second Gateway/Anybus reads nodes 4-6.

  • I have attached the User Manual for the Gateway below.

  • I have not installed any terminating resistors

  • Most of my data does appear to be correct.
