Highly scalable
The CM30 is highly scalable in terms of both hardware and software, to fulfill the demands of the simplest to the most complex
process. The basic CM30 meets the needs of a simple control loop. Templates and control functionality can be increased by
adding function keys to the basic model. Each function key added provides additional templates and functionality as shown in
Fig. 1, while retaining previous templates and functionality. For I/O builds, see also Ordering information on page 23.
