The line contains the parameters that are assigned the values that are to be included on the symbol list. The structure of the line is always platform-dependent. The following example shows a line for the symbol table in Step7 with replace variables.
"M8B_Symbol_M8E","M8B_Adresse_M8E","M8B_Typ_M8E","M8B_Bezeichnung_M8E"
This line defines four parameters, all with the data type UNKNOWN_TYPE. In this example, it can clearly be seen that the replace variables are surrounded by two tokens which can be adjusted via the model variables in the PLC group.
