For some time now the Programmable Logic Controller (PLC) has been the heart of most Control Systems throughout industry. While there is a lot of talk about "Soft PLCs" - Personal Computers which do the job of a PLC - the PLC remains in vogue because of it's proven track record.

• the heart of today's automated systems
• the most cost-effective method of control
• the most reliable method of control
• your staff feel comfortable with PLC Ladder Logic
• Process changes implemented easily and quickly

There is a large range of PLCs available on the market - some suited to small budget jobs, and some suited to larger networked jobs.

We have a wide range of experience in programming PLCs which include Allen Bradley's SLC500s and PC5s, Schneider's Modicon range, Siemens, Mitsubishi, Fuji, GEM80...

It is important that the PLC program be tough, easily navigable by maintenance staff, and written in such a way that changes to the control process can be quickly implemented. So the program must be accompanied by lucid comments which clearly explain the logic. Sapeca provides a separate easy-to-understand manual which explains the Control System in addition to the well-commented program.

All of our programs contain full alarming subroutines as well as a 'Cause of Last Stop' algorithm which determines and latches which fault was the actual cause of a system failure.
