ProtoLink developed a DDE server for polled and quiescent mode communications with Tesco Liquitronic 4 and Liquitronic 5 programmable controllers.
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.
