Overview (Inside Front Cover) - CAL Controls CALCOMMS 9300 Manual

OVERVIEW
TM
CALCOMMS is a graphic WINDOWS
package designed for PC supervision of CAL Model 3300
and Model 9300 controllers. It offers the capability of
remote adjustment, instrument configuration, cloning, saving
and retrieving instrument settings to files together with
logging and charting in real time.
Communication uses the MODBUS
fully isolated RS232 or RS485 link depending on the number
of instruments and the transmission distances involved in the
application.

PC Requirements
To gain the full benefit of CALCOMMS software, it is
recommend that the PC is fitted with a Pentium processor
and is running WINDOWS 95 or Windows NT programs. A
minimum of 16 Mb RAM is recommended to run the
program, together with enough free hard disc space to
meet logging requirements.
This manual assumes that a mouse or other pointing device
will be employed, but alternatively or in an emergency the
standard WINDOWS key convention can be used to operate
or close the program.
Because the controllers are "stand alone" they do not need
PC supervision for their normal function, and will continue to
control the process unaffected by failure of any part of the
communications loop.
