Came across one thread with the implementation of the protocol exchange between the S7-300 and counters e / e 1800 by Elster Alpha?
If so,

1) for a description of the manufacturer protocol requested dopolitelnuyu amount.
There is a description of the protocol or description of the ASCI C12.20?

2) Do not use if change in the exchange of the exchange parameters (speed, parity, ...)?
