4.2
Using the Software in Custom Configurations
The bridge software can be used in custom configurations in which you supply
your own PC and network interface hardware.
4.2.1 Minimum Requirements for Custom Bridge Configurations
Minimum requirements for custom bridge configurations are:
H 386 or faster PC
H Minimum 1 MB RAM.
H DOS 5.0 or higher
H Ethernet card with packet driver and configuration software
H Modicon SA85 Modbus Plus card.
4.2.2 Setting Up a Custom Bridge Configuration
The general procedure you should follow for installing the bridge software in a
custom configuration is:
H If your Modbus Plus network application is currently active, ensure that it will
not be disrupted by the addition of the new bridge node.
H Install your Modicon SA85 Modbus Plus card using the guidebook supplied
with the card. See section 2.2 in this bridge manual for information about
setting up the card’s Modbus Plus node address.
H Install your Ethernet card using the guidebook for that card.
H Connect the Ethernet and Modbus Plus network cables to your cards.
H Install your Ethernet packet driver according to the instructions supplied with
that program.
H Copy the Bridge Software (31000020) disk files to the root directory of your
bridge PC, except for AUTOEXEC.BAT and CONFIG.SYS. (You will be
using your existing AUTOEXEC.BAT and CONFIG.SYS files.)
H Note that your root directory now contains a GATELOOP.BAT file. This is
the file which will start the bridge application.
H Edit the GATELOOP.BAT file to remove the call to the bridge’s Ethernet
driver PNPPD.COM. (You will be using your own driver.)
