In addition to multiloop PID control, CALogix has integral logic functionality to provide enhanced machine control capability. The base unit houses the CPU, power supply and RS485 communications with Modbus RTU protocol. Up to four control modules can be added to each base unit and are available as PID or I/O variations. The PID module has full functionality similar to that of a mid-to high-end profiling temperature/process controller with options for sensor or linear inputs with relay, solid-state relay driver or analog outputs. Features such as PID autotune, heat-cool and up to 31 programmable profiles to a maximum of 126 segments are standard, ensuring that the requirements of most control loops can be met within this module.
