ag_info

The function ag_info reads the issue level of the PLC software and the PG
interface as well as the MLFB number of the PLC and stores them in a storage
area of the
The issue levels must be interpreted as integer values, the MLFB numbers as
ASCII values:
buffer[0] - buffer[1]:
buffer[2] - buffer[3]:
buffer[4] - buffer[24]:
If there were no errors, the function supplies 0 as the return value, otherwise an
error message which can be evaluated in accordance with the error table (see
