8.16 CC-Link IE Field Network Synchronous Communication Function
8.16 CC-Link IE Field Network Synchronous Communication
Function
This function performs A/D conversion with a synchronization period of the master station that supports the CC-Link IE
Field Network synchronous communication function.
This enables the A/D converter module to operate at the same timing of other slave stations on the same network.
(1) Supported versions of the modules and software
The table below lists modules and software required to use the CC-Link IE Field Network synchronous
communication function.
(2) Restrictions
This section describes restrictions to use the CC-Link IE Field Network synchronous communication function.
(a) Restrictions to use this function with other functions
(b) Restrictions on the number of A/D conversion enabled channels
There are restrictions on the number of conversion enabled channels for the A/D converter module depending
on the settings of the synchronization period of the master station and "Conversion speed setting" of the main
A/D converter module. For details, refer to the following:
Page 140, Section 8.16 (4)
(c) Restrictions on the network parameter settings (RWw/RWr)
In the RWw/RWr settings of network parameters, set the network parameters so that RWwF/RWrF are
assigned.
Module and software Serial number (first five digits)/version of GX Works2
Simple motion module 15092 or later
GX Works2 Version 1.525X or later
RJ71GF11-T2 or RJ71EN71 (no restriction)
GX Works3 Version 1.005F or later
Function name Restrictions
Averaging processing
Performs the sampling processing.
The setting of "Averaging process setting" will be ignored.
Conversion speed
switch function
The conversion speed is determined by the value of "Conversion speed setting" as in the following:
• With "Conversion speed setting" set to a value of 100μs: 100μs/channel
• With "Conversion speed setting" set to a value of 400μs or 1ms: 400μs/channel
The conversion processing of the A/D converter module synchronizes with the synchronization period set in the
master station.
For the conversion timing, refer to the following.
• Page 136, Section 8.16 (3)
Shift function
Cannot be used.
The setting of CH Shifting amount to conversion value (RWw2 to RWw5, RWw12 to RWw15) will be ignored.
Difference conversion
function
Cannot be used.
Turning on CH Difference conversion trigger (RY14 to RY17, RY24 to RY27) from off does not allow difference
conversion to start.
Extension I/O function
The extension I/O module can be used, but input and output of the extension I/O module is not synchronized with the
operation cycle of the simple motion module.
Cyclic data update
watch function
The setting of Cyclic data update watch time setting (address: 0007H) will be ignored.
