Chapter 11 Transmission Time; Transmission Cycle Time; Transmission Cycle Time Of The Nz2Aw1C1By; Effects Of The Double Check System - Mitsubishi Electric CC-Link-AnyWire Bitty Bridge User Manual

CHAPTER 11
This section describes the transmission cycle time and transmission delay time of AnyWire Bitty.
11.1

Transmission Cycle Time

The transmission cycle time is the time required for a bridge module and all the slave modules to update I/O data.
11.1.1

Transmission cycle time of the NZ2AW1C1BY

The transmission cycle time of the NZ2AW1C1BY is listed in the table below.
Number of occupied stations

11.1.2

Effects of the double check system

(1) Input
Unless the same data is received twice successively on the NZ2AW1C1BY side, the input area data is not
updated. Therefore, a minimum of one-transmission cycle time and a maximum of two-transmission cycle time
are required as the data response time.
Therefore, when a 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.

(2) 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.
