By online import from PLC the IEC60870 Master driver (zenon / zenon Logic) proposes to create also variables for 'connection status' - two variables of Type ID = 0 and with IOA=0 ("connection status") and IOA=1 ("status of Data Link layer").The variables created by driver are working in the RT without problems, but in Editor the variable names and COA value are wrong:
- the driver sets COA to the number of last sector found in PLC. The driver should set COA=0 as the T00 variables are general for PLC, not sector specific. Note: in the RT the driver ignores COA value.
- in variable name '[xx] T00 21.0' where '21' is now last sector (COA) there should be '0'.
- the driver writes in import dialog for both variables the same description 'connection status'. The driver should write 'connection status' only for variable with IOA=0, the variable with IOA=1 is 'status of the DL layer'.

Issue was addressed in procedure of online import of variables.
