Omega Engineering CN9400 - Manual (Page 6)

Introduction
INTRODUCTION
The CN9400 is a 1/16 DIN dual display, dual output miniature
controller with PID control strategy.
Control can be optimised with a single shot autotune either on
initial warm-up or at setpoint. The second setpoint can be
configured in a variety of alarm modes or PID Heat-Cool strategy. A
programmer offers a single ramp to setpoint with a choice of timed
soak period before switching off the output.
Control of non temperature processes is achieved by the provision
of linear input ranges and scaling in commonly used engineering
units.
Serial communication is available as an option, and the easy to use
CN9-SW is a graphic WINDOWS TM based software package designed
for PC supervision of up to 32 instruments, for remote adjustment,
configuration, cloning, saving and retrieving settings to files and
logging and charting in real time.
CN9-SW uses the MODBUS ® protocol via either a fully isolated RS232
or RS485 link depending on the number of instruments and the
transmission distances involved in the application.
A users manual is supplied with the comms option. For more
information contact OMEGA. For details, see rear cover.
It is suggested that users read the OVERVIEW section of this manual
before any installation or setting-up procedures are undertaken.
Note: The controller will not be operational until either the
QUICK-START or SET-UP procedure has been completed.
NB: Please note that in program mode, functions
are shown in the upper display (green) and options
in the lower display (orange)
