ABB CM15 Universal Process Indicator 1/8 DIN
The ABB CM15 ControlMaster is a feature-packed 1/8 DIN universal process indicator.
A crystal-clear, full-colour, TFT display shows operators exactly the information they need to know and provides operation and configuration menus in full text making the ABB CM15 intuitive to use and very quick to install and commission.
Available as a basic indication-only model, or enhanced through plug and play function keys and I/O modules, the ABB CM15 offers totalisation, level, math, logic, counter and alarm functions making it extremely flexible and able to solve many tricky application requirements. Modbus, Profibus and Ethernet communication options ensure easy integration and connectivity to supervisory or control systems.

How to Setup a Totaliser on an ABB CM15
ABB CM15 Powerful Operator Display
The CM15 features a full-colour 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 CM15’s display.
Extensive customisation 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 indicator’s diagnostic log.
Exceptionally easy to use
The CM15’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 alarm acknowledgement and display selection, to be accessed easily by the operator.
ABB CM15 Problem Solving Flexibility
Extensive functionality is available to provide flexible problem-solving capability; making the CM15 much more than just a process indicator.
Process alarms
8 independent process alarms can monitor any analogue signal within the CM15, enabling extensive process monitoring capability. Alarms can be used to drive physical outputs or soft-wired to other functions within the indicator.
Real-time alarms
The ‘alarm clock’ functionality provided by the CM15’s realtime alarms enables time-of-day decisions to be introduced into the indicator’s actions or specific functions to be triggered routinely at specified times.
Delay timers
Event sequencing is enabled through the use of the CM15’s delay timers. A predetermined delay and output duration can be programmed into each delay timer and timers can be linked together.
Custom linearisers
The CM15 has 2 independent 20-point custom linearizers that can be applied to any analogue signal within the indicator. These linearisers can be used in applications such as level-to volume conversion of a non-linear tank level or to accommodate special input signals or output devices.
Math
8 math blocks provide arithmetic, averaging, min. / max. hold, square root and signal switching functionality. Simple equations can be performed in a single math block or multiple math blocks can be nested together to construct complex equations. Signal switching ‘multiplexing’ math blocks switch between 2 analogue signals based on a trigger signal. For example, a backup sensor could be selected automatically on failure of a primary sensor.
Logic
8 comprehensive logic equations provide powerful interlock functionality. Inputs and outputs of the logic equations can be soft-wired to any digital signal within the indicator to maximize flexibility.
Totalisers
Two totalisers are available on the ABB CM15. The totalisers can configured to perform multiple functions:
- Integration against an analogue signal to totalise flow
- Counting digital pulses
- Totalisation of flow based on a frequency signal from an electromagnetic flow meter
Frequency input
For maximum accuracy the ABB CM15 can accept a frequency signal from an electromagnetic flow meter. The frequency signal can be totalised and displayed; an instantaneous flow rate can also be calculated and displayed on screen.
How to Setup an ABB CM15 Indicator as a Batch Controller
ABB CM15 Communications
Extensive communication options enable the CM15 to be integrated into larger control systems easily or connected to other process instrumentation.
RS 485 MODBUS
Using RS 485 MODBUS, values and status can be communicated to and from the indicator in real-time via an RS 485 connection.
Ethernet
Optional Ethernet communications enable ControlMaster to be integrated in to an Ethernet network quickly. The following functionality is provided:
- Email
Notification of a critical process event or status can be made by email. Multiple events can trigger an email that can be sent to multiple recipients
- Webserver
- ControlMaster’s integrated webserver enables the current status of the process and indicator to be viewed remotely using a standard web browser
- MODBUS TCP
- Process values and status can be communicated to and from the ABB CM15 in real-time using MODBUS TCP, enabling it to be integrated easily into larger control systems or connected to a data recorder.
ABB CM15 PC Configuration
The ABB CM15 can be fully configured using ABB’s ConfigPilot software.
Available free of charge, ConfigPilot enables off-line creation and editing of configuration files.
Configurations are transferred to and from a controller via its standard IrDA port and a USB IrDA adapter.
ABB CM15 Bank Control
Bank control enables improved control of multi-element output devices such as banks of heaters, pumps and fans.
Aimed at minimizing wear caused by over-use of one specific ‘duty’ device, bank control enables wear to be levelled by sharing duty and assist handling between every device in the bank.
Ideal for pump control applications in the water and waste water industry. Up to six pumps can be controlled each with independent on and off trip points.
The ABB CM15’s universal process input, complete with transmitter power supply, makes it suitable for connection to many kinds of standard level transmitters.
Bank control provides users the choice of either ‘Rotate’ or ‘First In, First Out (FIFO)’ wear-levelling schedules. Rotate cycles which pump is the first to switch on during a pumping event. FIFO ensures that the last pump to switch of is the last pump to be called again.
