Appendix 5
Processing Time
This section describes the processing time related to the transmission of AnyWireASLINK.
Transmission cycle time
In the transmission cycle time, I/O data of the FX5-ASL-M and all the slave modules is updated.
The following table lists the transmission cycle times of the FX5-ASL-M.
Update timing of I/O data
Input
Unless the FX5-ASL-M receives the same data twice successively, data in the input area is not updated.
A minimum of one-transmission cycle time and a maximum of two-transmission cycle time are required as data response
time.
Therefore, when input data is shorter than two-transmission cycle time, the input data may not be captured depending on the
timing.
To ensure the response, provide an input signal that is longer than two-transmission cycle time.
■
Case of minimum data response time
If no change is detected in input data between two sampling timings, communication in one-transmission cycle time is
possible.
■
Case of maximum data response time
The input data is changed after a sampling, and thus the next sampling will be the first data reception. Time equivalent to two-
transmission cycle time is required.
Output
As the double verification is executed on the slave module side, the time required is the same as that for input, namely a
minimum of one-transmission cycle time and a maximum of two-transmission cycle time.
