Notes for Logging

Mode A: Channel Logging Menu

When you invoke the Channel Logging mode A (On) or a (Off), you will be

prompted with the message:

Enter M

for MBP initiated sessions

T

for TCP initiated sessions

B

for both

Session initiator? _

Enter: M to select sessions initiated from Modbus Plus, T for sessions initiated

from TCP/IP, or B to select sessions initiated from either network.

Next you will be prompted:

Please enter the sessions you want to (un)log (a-p)
Enter

X when done,

T to log all sessions

Session? _

Channels are identified by 16 letters: a...p. The channels are made available to

incoming transactions as they become open within the bridge, with p being the

first available channel. Note that the letters a...p correspond to the sequence in

which the channels are made available. They do not correspond to a specific

Program path or Data path number.

For example, if the bridge is inactive when it receives a transaction, the transaction

will be processed on channel p. If the transaction is initiated from Modsoft and

requires both a Program path and a Data path, then it will be processed on two

channels, p and o.

Channels are freed for new transactions in the order p ----> a as they become

available.

Saving the Logging Status and Log File

The current logging mode is saved to the WATTCP.CFG file in the field:

log_level=<level>

where <level> is the currently selected mode.

defaults are:

log_errors

(all TCP/IP and routine errors)

log_channels (all channels)
log_messages

(all routine messages)

Both the WATTCP.CFG and the BRIDGE.LOG file can be uploaded to a host.
