Detailed Description

This module contains the Midas Front End code for the Twist TEC Gas Handling PLC interface.

A link is made between the Midas database and the PLC, allowing monitoring of the PLC state and logging of various values. It is intended for installation as another front end running on E614Slow.triumf.ca as part of the Twist DAQ system
