ProtoLink developed a 32-bit multithreaded DDE Server for the Tesco Liquitronic
4 and Liquitronic 5 programmable controllers. These devices, which are
used extensively in the waste-water industry, can be configured to operate in
quiescent (cry-out) mode.
The Liquitronic server was developed using the Wonderware DDE Server Toolkit
and is ProtoPort compatible. It supports
scheduled or interval polling and is capable of receiving unsolicited messages
via ProtoPort.
This driver has been fielded in a multi-protocol environment in which it shared
a single radio channel with our Tano Aquatrol W1500 driver.
Both drivers receive unsolicited messages from their respective controllers via
ProtoPort.
