When loading the symbol of a PLC main element, it is analysed and the inputs/outputs which are available determined from this analysis. All information is then pooled in a PLC project database. The connection numbers and connection identifications are automatically transferred from this when inserting the inputs/outputs (auxiliary elements).
Important
Only those auxiliary modules can be assigned where the letters of the pin name (which have already been assigned in the symbol) match those in the main module.
Example
The table shows an example of a designation of inputs/outputs on the symbol main element and the possible designations of the individual inputs/outputs of the symbol auxiliary element.
