Figure 2. PMCS DDE Server: EI Protocol RS-485 configurations.

The differences between the three versions of the Server are minor and, except where noted the software is functionally identical. The Modbus-host version of the PMCS DDE Server is the focus in this document; differences in the TCP/IP versions are noted when present. The Modbus version of the server may be used to service local RS-485 ports directly from the host PC, as well as remote serial ports accessed via the Ethernet Gateway over TCP/IP communications. Another variant of the DDE server works in the same way as the Modbus RS-485 DDE server on EI Protocol.

In the interest of brevity, we’ll refer to the PMCS Network and Device Configurator with DDE Server as “the PMCS DDE Server” or simply “the Server” – be aware that this document describes only the PMCS DDE Server. The information herein is not intended to apply to other DDE servers.
