The usage of coordination flags is parametrized. In a high byte the byte number of
the coordination flag must be parametrized and in a low byte its bit number must
be parametrized. If no coordination flags are used, a value of 255 in high and low
byte is to be entered.
Access to the target area is controlled with a coordination flag:
If the flag is not set in the foreign PLC, this means that the data is not valid in the
foreign PLC. The foreign PLC sends the error number 50 decimal back to ones
own PLC. The data handling block FETCH registers with the display word:
“Finished with error“ error number: 50
