Appendix 5

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.
