Transmission cycle time of the bridge module
The transmission cycle time is the time required for the bridge module and all the slave modules to update I/O data.
Transmission cycle time of the bridge module is as follows.
Number of transmission points
128 points (input: 64 points, output: 64 points)
256 points (input: 128 points, output: 128 points)
384 points (input: 192 points, output: 192 points)
512 points (input: 256 points, output: 256 points)
Effects of the double check system
■Input
Unless the same data is received twice successively on the bridge module side, the input area data is not updated. A
minimum of one-transmission cycle time and a maximum of two-transmission cycle time are required for the data response.
Therefore, when input signal 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.

■Output
As the double check is performed 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.
