Configuring the Bridge
27
3.1.3 Files Generated or Modified by the Bridge
When the bridge is configured using the CFGUTIL program, it writes ASCII text
files that record the bridge’s current configuration and network mapping. The files
are retained in the bridge and referenced for configuration on subsequent startups.
Table 16 Files Generated or Modified by the Bridge
File Purpose
RTE.CFG Contains the bridge’s MB+ and TCP mapping
WATTCP.CFG Contains the bridge’s IP setup and network parameters
RTE.OLD Contains the RTE.CFG version prior to the last write
WATTCP.OLD Contains the WATTCP.CFG version prior to the last write
These files can be uploaded and stored in a host. They can be downloaded to
restore a bridge’s configuration. Sections 5.2 and 5.3 describe these procedures.
Note that RTE.CFG must be renamed to RTE.TXT prior to downloading.

3.1.4 The Software Startup Sequence
On power--up the bridge software performs the following sequence.
H CONFIG.SYS loads the Modbus Plus driver MBPHOST.SYS.
H AUTOEXEC.BAT calls GATELOOP.BAT.
H GATELOOP.BAT executes BDRESET.EXE, initializing the Modbus Plus card.
H GATELOOP.BAT executes the Ethernet driver program PNPPD.COM.
H GATELOOP.BAT executes the bridge application program SGATE.EXE.
