Overview
The ControlMaster CM10 is a flexible, 1/8 DIN, universal PID process controller. Detailed process information is presented clearly
on the CM10's full-color TFT display and an intuitive operator interface simplifies configuration and operation.
Scalable in both hardware and software functionality, a CM10 can be specified easily to meet the needs of your application
requirements. Flexible control functionality including on / off, time proportioning, analog PID, split output control and math & logic
make the CM10 suitable for a wide range of process applications.
Fully configurable via the easy-to-navigate front panel menus or PC configuration software, the CM10 can be commissioned
rapidly and then tuned via the advanced autotune functionality.
MODBUS and Ethernet communication options ensure easy integration into a control system.

Scalable functionality
The CM10 is scalable in terms of both hardware and software, enabling it to meet your application requirements. The basic CM10
meets the needs of a simple control loop. Additional templates and functionality can be enabled by adding a function key to the
basic model as shown in Fig. 1, while retaining previous templates and functionality. For I/O builds, see also Ordering information
on page 19.

Powerful operator display
The CM10 features a full-color 5.5 cm (2.2 in.) display for
displaying detailed process information to the user. Process
details such as alarm messages and diagnostic information are
displayed clearly in full text without the need for difficult-to read scrolling displays.
Example of an operator page
Automatic selection of standard display templates immediately
makes best use of the CM10's display. Extensive
customization features then enable the displayed information
to be tailored to suit the process requirements.
Diagnostics and alarm status display
The diagnostics and alarm status display provides detailed
information on any active alarm or diagnostic condition. The
operator can see, at-a-glance, the status of any alarm
condition present within the process. Additionally, diagnostic
messages are presented clearly to the operator, enabling rapid
notification and simple diagnosis of any critical instrument
status condition.
Historical information of diagnostic messages can also be
viewed in the controller's diagnostic log.

Exceptionally easy to use
The CM10's full-text display and simple-to-navigate, pop-up
menu makes operation exceptionally easy.
A programmable soft key enables commonly used functions,
such as auto / manual selection, alarm acknowledgement and
display selection, to be accessed easily by the operator.
Flexible control functionality
The CM10 features flexible control functionality making it
suitable for a wide range of applications. Features include:
Autotune
Once initial configuration is complete, a powerful autotune
facility enables automatic calculation of the PID values
required, enabling rapid commissioning of the CM10.
Gain scheduling
The CM10's gain scheduling functionality is used for efficient
control of non-linear processes. Up to 3 different sets of PID
parameters are selected automatically from a reference signal
ensuring optimum control response, regardless of the process
status.
Split output control
The CM10 can also be configured to perform split output
control, for example, when both heating and cooling of a single
process is required.
Remote auto / manual switching
In addition to switching via the front panel, the CM10 can be
switched between automatic and manual control mode using
an external signal. When switched to manual mode via a digital
signal, the value of the control output can be preset, for
example, to open a control valve automatically during a
cleaning cycle.
External setpoint selection
The CM10's control setpoint can be selected via external
digital signals, for example, simplifying operation by selecting
different setpoints using external push buttons.
