When the result is a normal completion, '-' is displayed.

● Execution log option
The registration conditions of logs can be specified by the execution log option specification for buffer memory
(buffer memory address: 40E2
H, 40F2H) or by the various control designations of the intelligent function module
utility.
The following are the registration conditions.
0th bit is OFF (0): Stores the execution log for the protocols with the error completion only.
0th bit is ON (1) : Stores the execution status and the execution logs of all protocols.
Note that, only the logs of error protocols are displayed at the default setting. To display all protocol logs, set the
registration condition in "Execution log options" of the various control designations in the intelligent function
module data.
