PLC Programming

Programmable controllers are at the core of process control. These controllers may be small, Programmable Logic Controllers – PLC and Programmable Electronic Safety-related Systems – PES.

SEID has been successfully implementing programmable controllers since our company’s founding. In fact, we are a leader in the process-control industry, recognized as an authorized System Integrator (SI) by all major industrial programmable controller manufacturers.

SEID‘s success and recognition as a programmable controller system integrator can be attributed to our 20+ years of experience and our proven project methodology that includes:

  • Documenting programs with instruction comments, tag descriptors, rung comments and annotated program files
  • Utilizing standard template methodology that includes repeated functions such as motor control, valve control and analog input control.
  • We have developed templates that include:
    • Motor control
    • Valve control
    • Analog monitoring
    • Discrete alarms
    • PID control loops (feed forward, cascade, etc.)
    • Alarm sequence

Our process-control programming expertise has been applied across many industries for many different process applications, including:

  • Standards development
  • Sequences
  • Lead/lag logic
  • Mass balance logic
  • Load-sharing logic
  • Checked I/O logic
  • Alarm handling
  • SCADA systems
  • Languages–Ladder Logic, Sequential Function Chart, Structured Text, Function Block Diagram
  • Safety Instrumented System (SIS) with Safety Instrument Function (SIF)
  • Functional Safety of Electrical/Electronic/Programmable Electronic Safety-related Systems
