Error detection timing when 2 is set for Communication Retry Count
Ex.
Interval
The error is detected if the destination device does not respond or communications fail by when the following time has
passed: (Communication Retry Count + 1)  Communication Time-out Time
(a) Precautions for retry of communication
• Communications at a specified execution interval (when "Fixed" is set for Communication Setting) or
communications according to the on status of Request Contact (when "On Request" is set for
Communication Setting) are ignored during retry of communication because that period is regarded as
Communication Time-out Time.
• During retry of communication, the data at the time of communication error is sent to the destination device
(for writing of device data) and the data at the time of the retry of communication is received (for reading of
device data).
