5.3 L_IOCompactModule − Coordinate data
Function block L_IOCompactModule supplies the digital input and/or output data of the I/O system
and is used for compact module EPM−T83X.
The block represents the interface between PLC and I/O system.
·
Via inputs abyPDO_DataToIO, data are transmitted from the control to the I/O system
(digital/analog output channels).
·
The states of the digital and analog input channels are transmitted to the control via outputs
abyPDO_DataFromIO.
·
This function block is made up of unassigned CAN objects so that the status display at
outputs nState... is the same as for the CAN library’s transmit and receive blocks.
