DeviceNet network configuration was easy. Unable to get RTU to communicate. We have a 4 wire RS485. I have to use a RS422 - RS232 adapter to allow the handshaking and keep our DCS system (Emerson Ovation) from reporting ‘Comm Failure’. Anybus is configured as RS232 and RTU address 1.
I’ve tried different I/O register sizes to get some response. Address overview looks incomplete. Set operation mode screen has ‘Unavailable’.
Seems the Anybus gateway isn’t recognizing the Modbus address poll from Allen-Bradley E3 overloads. Our DCS is requesting device status (word), and phase current (3 integers).
