Configuring the Connection
The software communicates with the instrument using
Modbus via the RJ11 configuration socket located on
the underside of the case, or via the Ethernet or RS485
options if fitted. Refer to the wiring section for connec-
tion details. The configuration socket is intended for
initial configuration before installing the instrument in
the application. An RS232 to TTL lead (available from
your supplier) is required to connect this socket to your
PCs RS232 serial port or USB to RS232 adaptor. A
front mounted USB port is available on some models;
this can also be used to configure the instrument or
transfer profile files, via a USB memory stick.
ELECTRIC SHOCK/FIRE HAZARD. The configu-
ration lead/socket is not isolated from the pro-
cess input or SSR Driver outputs. It is not in-
tended for use in live applications. Failure to
follow these instructions could result in per-
sonal injury or equipment damage.
A communications settings screen is shown whenever
the user attempts to connect to the instrument from the
software. If the settings are not in-line with the informa-
tion below, the software may not be able to communi-
cate with the instrument.
Connection from PC to Bottom Configura-
tion Socket
When using the built-in configuration socket, set the
communications parameters as shown here and in the
following table.
• Device connector = Configuration Socket
• PC connector = the PC Serial Com port number you
are connected to
• Start and Stop bits = 1
• Data bits = 8.
• Parity, Bit Rate & Address = must match settings in
the table below
Note:
When uploading or downloading via the bot-
tom mounted configuration port, the required soft-
ware communication settings depend on the mod-
ule fitted in slot A. See the table below.
