CM10
1/8 DIN panel-mounted universal controller. Compact control for ON/OFF, time-proportioning, analogue PID and motorised valves. Ethernet and MODBUS available.
ABB ControlMaster
PID regulators and controllers
A shared platform for local control of temperature, pressure, flow, level, pH and other variables. Models mainly differ in size, I/O and control strategy capabilities.
CM30
1/4 DIN panel-mounted universal controller. Scalable single/dual functions, cascade, profiling, maths and logic for more complex applications. Often the standard choice for Commander C-series retrofits.
CM50
1/2 DIN panel controller with a 3.5-inch display, dual loops and strategies such as cascade, feed-forward, ratio, predictive and adaptive control, plus maths, logic and totalisation.
CMF310
Wall- or pipe-mounted field controller, fully rated IP66/NEMA 4X. Extended and dual-loop functionality, with up to four control/retransmission outputs and six relays depending on configuration.
CM15
1/8 DIN universal indicator with thermocouple, RTD, mA, V, mV and frequency inputs, totalisation, level, maths, logic, counters, alarms and Ethernet/MODBUS.

When to use it / when to consider alternatives
Standalone controller or centralised control?
Standalone works well when
- there are one or a few local loops
- operation must continue without the PLC/DCS
- a retrofit must avoid changes to central software
- operators need a clear local interface
PLC/DCS is preferable when
- many loops interact
- complex sequences, interlocks and batch logic are required
- historical data, cybersecurity and central management are priorities
- maintenance must be coordinated at system level
Best practice
PID installation and commissioning
Before tuning, check range, linearisation, engineering units and sensor-failure behaviour.
4–20 mA, time-proportioning, relay and motorised-valve outputs require different logic and timing.
The process must be sufficiently stable, and the test must be able to change the output safely.
Manage output saturation and automatic/manual transfer to avoid large overshoots on return to control.
Excessive filtering slows the loop. Noise and unstable sensors should not be addressed through tuning alone.
Stiction, deadband and an oversized control valve limit control more than any PID parameter.
ABB replacements
Commander → ControlMaster
Typical migrationABB identifies CM30 as a replacement for several 1/4 DIN Commander controllers, including C200, C300, C350/C355 and C360. CM15 replaces the C150 process indicator. Before quoting, we check I/O, profiles, maths, logic, communications and panel dimensions.

Technical FAQ
Controller FAQ
CM10, CM30 or CM50?
CM10 is the most compact and suits standard loops. CM30 adds more I/O and cascade or profile functions. CM50 suits dual-loop control and more complex strategies.
When should I choose CMF310?
When the controller must be installed directly in the field without a dedicated cabinet. It is fully IP66/NEMA 4X and can be wall- or pipe-mounted.
Can CM15 control a valve?
CM15 is an indicator, not a PID controller. It supports alarms, totalisation, maths, logic and communications. Use CM10/30/50/CMF310 for PID control.
What does autotune do?
It estimates initial PID parameters. It provides a starting point; final tuning must be checked against actual process dynamics and valve limits.
When should cascade control be used?
When a slow primary variable can be controlled better through a faster secondary loop, such as temperature with an inner steam-flow loop.
When should feed-forward be used?
When a measurable disturbance affects the process and can be compensated before a setpoint error develops.
Standalone controller or PLC/DCS?
Standalone controllers suit a few local loops, retrofits and operational independence. PLC/DCS suits extensive logic, coordinated loops, historians and central management.
