When using a Rockwell PLC from the Micro Family, some specifications need to be applied to poll values.
Unable to use Ethernet IP
The Ethernet/IP of the Micro 8xx Family can't be combined with the eWON Flexy. Instead the Modbus protocol should be activated/used in the PLC and the Modbus I/O Server must be configured in the eWON.
Hereunder is the configuration of the Rockwell PLC to set the Modbus protocol:
- Double click on Micro 8xx label
- Select the "Modbus Mapping"
- Associate a Modbus address to the PLC variables
