1 Values in parentheses are assumed that service processing is set to 4 times (refer to (2) (a) in this
section).
2 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.
• Setting "100ms" for the setting unit of arrival monitoring time
