SCADA

SIEMENS PLC & SCADA based Material Handling System

We have automated the tile manufacturing plant with recipe control from SCADA. We have integrated SIEMENS and SCHNIDER SCADA with Siemens s7 200 and SCHNIDER M340 PLC and VFDs. The Auto/Manual operation of plant is equipped with bypass system using contactors so that manual operation can be done even if there is no PLC and SCADA. The colour combination of tiles can be set from SCADA and the materials amount can be given from SCADA.

Project Goals and Targeted Benefits:

Up to date, reliable SCADA system
Significantly better documentation of the SCADA system
Implementation using SCADA standards
Optimized water treatment plant automation strategies
Much greater access to historical SCADA information

Project Drivers

Existing SCADA servers, software, and PLC’s were at the end of their asset life
No longer able to get spare parts
Unreliable wide area communication
Increased demands by regulators for better operation
