I am bench testing a setup with the AB7072 to the Danfoss EKE 347. RS485 Modbus RTU configuration. ControlLogix using the AB7072 EDS for Ethernet Device.
I am trying to read just a single integer. The ControlLogix and Node Monitor only shows zero for the cyclic reads.
I have verified via the Node Monitor manual message sends and the Log File that the message data is returned correctly.
I can also write correctly to the Danfoss though it isn’t in the attached configuration.
ControlLogix shows no errors in the connection.
LED Lights 1 and 2 on solid Green
LED 3 off (No Ethernet Connection to Input Port)
LED 4 Green Blinking Fast (Ethernet Connection to Output Port)
LED 5 Red Solid
LED 6 Green Blinking slowly
Configuration looks good to me. Query and Response configured for 1 register / 2 bytes.
Only zeros ever cyclically received. Manual command / log shows good data.
Any suggestions with why LED 5 is red and all zeroes?
Thanks and here are my files…
