8 DATA COMMUNICATION USING THE PRE-DEFINED PROTOCOL
8.1.4 Protocol execution log storage function
The protocol execution log storage function allows you to confirm the detailed pre-
defined protocol execution status and results for each channel.
Up to 32 protocol execution logs can be checked.
If the number of the stored logs exceeds 32, the oldest log will be overwritten.
(1) Checking methods
The following two checking methods are available.
(a) GX Configurator-SC (Pre-defined protocol support function)
The logs can be checked in the "Protocol execution log" dialog box.
For details, refer to the Operating Manual (Pre-defined protocol support
function).
(b) Checking the buffer memory
The logs can be checked in the Execution log storage area (address: 4102
H
to 4701
H
(CH1), 4802
H
to 4E01
H
(CH2)).
For details, refer to Section 3.9.
POINT
Do not perform the above two methods at the same time.
The latest execution logs are not in the buffer memory while they are being updated
in GX Configurator-SC (Pre-defined protocol support function).
(2) Setting for protocol execution logs
Whether to store all protocol execution logs or only the failed protocols in the
Execution log storage area can be specified.
The following shows how the Execution log options area (address: 40E2
H
/40F2
H
)
in the buffer memory is set.
