OVERVIEWKey to Program Icons
Overview
CALCOMMSTM is a graphic WINDOWSTM based software
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®protocol via either a
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.

RS-232 Is the standard most widely used for interfacing
peripherals to PC's and is designed for serial
communications with single instrument up to a distances
of 15 metres, in a low electrical noise environment.
Connection is via a screened two core cable where the
voltage signal on each line is referenced to the screen
which is grounded. Most PC's have one or two RS-232
compatible ports fitted as standard.

RS485 Connections
RS-485 Is a half duplex serial communications link and is the
standard most commonly used for industrial applications due
to it's high noise immunity and multi-drop capability. It
enables a PC to communicate with up to 32 instruments
over distances up to 1200 metres, and requires the addition
of an RS-485 interface card, or a separate RS-232/485
converter.

Each RS485 interface has specific connection and
termination biasing requirements which will be detailed in
their installation instructions. The general principles are as
follows.
Terminations Because each wire is a transmission line, it
must be properly terminated to prevent reflections. Where
multiple instruments are daisy-chained together, a 120 ohm
terminating resistor should be fitted at the connection to
the PC and to the last instrument in the chain.

Bias resistors When transmission lines are not transmitting,
they remain in an indeterminate state which can allow
receivers to receive invalid data bits due to electrical noise
on the cable. To prevent this, the the lines should be forced
into a known state by fitting two 620 ohm bias resistors to
one point (node).
If an RS-485 interface card is being fitted to the PC,
separate bias resistors may not be needed because they
may already be fitted to the card. Check the manufacturers
specification.

Immediately after power-up, both instrument, and PC comms
settings need to be made compatible before communication
between them is possible. Instrument defaults are shown
below together with the available options.
ADDR (Address) This is a unique
identification number that must be
allocated to each instrument
connected to the network.
Default =0. Options;
1 to 247
BAUD (Baud rate) The setting determines
the serial communication data
transmission rate in bits/sec, and must
match the PC settings
Default =
9600
.
Options;
1200;2400;4800;9600 and 19200
DATA (Data) Sets the transmission format, and
must match the PC settings.

DBUG (Debug). Commissioning and

when the instrument is transmitting or
receiving data by rapidly flashing the
three horizontal segments of the first
and last digit of the display.
First digit = Tx; last digit = Rx
Default = Off. Options
off; on
Only use dbuG during commissioning or trouble-shooting
because it shares display segments and therefore
corrupts the normal display.
