Logging the Bridge’s Activity

Before running diagnostics you can build a log of the communication activity

performed by the bridge. This can help you to determine the kind of diagnostics

you may want to run.

You can set the bridge to log all traffic initiated on either its Ethernet network or

Modbus Plus network. You can also set it to log errors only.

How Logging Works

Logging is turned on and off through a keyboard and monitor connected to the

bridge. The bridge provides five logging modes. It writes the log results with

date/time stamping to a file BRIDGE.LOG, as well as to the monitor.

The BRIDGE.LOG file is self--wrapping and contains enough space for several

hundred lines of logging.

Note that logging will slow the throughput of any application running in the bridge.

Particularly the use of Mode C (TCP/IP Tick Logging) will generate constant

logging messages.

Setup

If a keyboard and monitor are not connected to the bridge, remove power to the

bridge and connect them to the bridge’s panel. Restore power to the bridge.

To invoke logging, the bridge application must be running. If the bridge displays its

CFGUTIL menu on startup, press Escape to close the menu. This should display

the bridge’s C:\ > prompt. Enter GATELOOP to start the bridge.

Starting Logging

With the bridge running, type a letter: A, B, C, D, or E (upper case letter) to select

a logging mode.

The logging modes are:

A Channel Logging.

B TCP/IP Error Logging.

C TCP/IP Tick Logging.

D Routine Logging.

E Routine Error Logging.

Stopping Logging

To stop logging type a letter: a, b, c, d, or e (lower case letter) to turn off the

selected logging mode. Type the letter f to turn off all logging.
