Automotive Manufacturing
SCADAware engineers produced a PC based SCADA system with four servers and 20 display clients on a Local Area Network (LAN). This system communicates with 370 Mitsubishi PLC's, and gathers approximately 30,000 I/O points for monitoring and reporting shop status. The network shown on page three combines three levels of communications networking. Data is transferred from a token passing deterministic PLC network to PLC data concentrators and from there serially via RS422 to the servers. The servers are on a combination cat 5 and fiber optic 100 mega-bit Ethernet designed and installed by SCADAware employees. This was the largest PC based SCADA system in the world at the time it was created and still is the largest in terms of the number of PLCs attached to a single database SCADA system.
