WAGO-I/O-SYSTEM 750
750-882 Media Redundancy ETHERNET Controller
• the PLC function of the PFC (CPU) and the I/O modules
• between the fieldbus master and the PLC function of the PFC (CPU).
If MODBUS is used as the fieldbus, the MODBUS master accesses the date
using the MODBUS functions implemented in the controller; EtherNet/IP, in
contrast, uses an object model for data access.
Data access is carried out with the aid of an IEC-61131-3 application program.
Data addressing varies greatly here.
