The references of the books are: R W Lewis, Programming Industrial Control Systems using
IEC (6)1131-3 (IEE, London,England,1998)and Karl-Heins John & Michael Tiegelkamp, IEC
61131-3 Programming Industrial Control Systems (Springer-Verlag,Berlin, followed by recent
date - I've returned the book). The first book gives only one example using a pair of
communication blocks, one send (USEND) and one recieve (URCV) with no examples on the other
ten application communication commands. I can't recall any examples in the second book. I
need to know how to map the communication blocks to a hardware PLC communications module,
and then write the code to produce the interface into the applications program. If anyone
can help,please contact me directly on [email protected] if the details are not of interest to other members. Thanks and Kind Regards. Clive Libotte.
