IO Table
The IO table enables the map of racks and units needed by the PLC programs to be edited. It also allows the
desired map to be compared with the actual map of the connected PLC when online. See the CX-Server PLC
Tools User manual for details on editing the table.
Some (usually smaller) PLCs do not have configurable IO, and so do not have an IO table.
Once IO assignments have been made, affected addresses are shown prefixed in CX-Programmer’s program
editors. An ‘I: ’ prefix indicates that the address is mapped to an input unit. A ‘Q: ’ prefix indicates that the
address is mapped to an output unit. Select
Show actual I/O bit in XY in the Diagrams tab of Options dialog to
change the prefix to ‘X: ’ and ‘Y: ’.
