PLC Programming

At AC Sys our PLC programming is produced to the strictest engineering standards. This is a core business aim: To ensure full transparency of the control logic, that is viable and maintainable by the end user. We don’t lock down code and ensure every network, operand and function is fully documented and commented, I/O is descriptive, and logic is structured into modular, organised blocks. We implement layered architecture (device, control, sequencing, safety) so responsibilities are clear, change impact is minimised and commissioning is simplified. Field bus communications and protocols are defined and verified, and version control with release notes ensures traceability.
