Standardizing Your PLC Variable Names
Laying the foundation for a control system that is easy to maintain, support, and upgrade starts long before equipment is purchased and installed. A key piece of this is developing a systematic approach to naming all your equipment – from your instrumentation to your programmable logic controllers (PLCs) –to provide consistency between your pipping and instrumentation diagrams (P&IDs), plant floor equipment, and human-machine interfaces (HMIs).
