Our field is contract operation and maintenance for steam boilers, generators and similar plant. We use various DCS for controlling the plant, and for complex sites we use PLC's and SCADA (RS View).
The PC's running the SCADA's are industrial rack-mounted units, running NT4. We are suffering regular failures where the PC's lock up and crash, often at least once a week. The worst sites are those which are either power generation (I am already investigating the electrical feeds to the PC's), or are not purely Allen Bradley PLC's. On one site our SCADA communicates with Mitsubishi PLC's, on another it's Siemens.
What is everybody else's experience? Are PC crashes common with SCADA's? Has anyone found any typical causes, and what were the solutions? Are third-party drivers not reliable?
