Programmable Field Bus Controller 750-833 Process Image • 63 The PFC variables are also configured through the hardware catalogue. From 1 to 64 bytes of input variables and from 1 to 64 bytes output variables may be configured for field bus controllers up to SW 03. In addition, there are PFC configuration modules available with data type information from SW 03. Note PFC output variables are defined from point of view of the programmable field bus controller. From the point of view of PROFIBUS, these are input variables. Accordingly, PFC input variables are output variables for IEC 61131-3 access of the field bus: IEC 61131-3 input variable = PFC output variable PFC input variable = IEC 61131-3 output variable Fieldbus PLC input variables PLC output variables Programmable fieldbus controller PFC input variables PFC output variables Fig. 3.4.2-10: Correlation of IEC 61131-3 variables and PFC variables WAGO-I/O-SYSTEM 750 Bus System g012444e
