Total processing time of the data link instruction (when the instruction is resent by the number of resends)
1 Since the arrival monitoring time value (default: 0) is smaller than the TCP resend timer value (default:
10s), the processing time will be the same as the TCP resend timer.

(c) Total processing time of the data link instruction (when the instruction is
resent)
The processing time can be shortened by setting the arrival monitoring time
shorter.
