Communication with PLC devices by the Satchwell company
The
Satchwell company supplies the
DDE server for communication with their PLC devices. The PROMOTIC application can be linked up by the
DDE communication to this server and thus it can communicate with these PLC devices. For the time being we don't have information who supplies the
OPC server to these devices.
It is possible to communicate with devices by the
Satchwell company also by the
SatchNet protocol. A simple form of this protocol allows to use for this communication in the PROMOTIC system:
PmChar - Driver for communication by user defined ASCII/BIN protocol.
