Selecting Synchronous
Data Select the type of synchronous data to be sent by each Motion Control Mod-
ule in the System Setup for that Motion Control Module, as shown in the fol-
lowing table.
Note The time for synchronous data exchange can be shortened by selecting No
data.
Prohibit System
Interruption of the Sync
Mode Use this function to keep the timing of the calculation start for each Motion
Control Module as close as possible, when using Sync Mode.
!Caution Do not set this function to Prohibit system interruption of the sync mode when
the cycle time is 10 ms or longer. Doing so may cause the System Clock Bits
to malfunction.
Note Settings are made using the CX-Programmer Ver. 5.0 @ menus.
5-5 DM Data Transfer
5-5-1 Outline
Large volumes of any DM data can be transferred between the Coordinator
Module and a Motion Control Module at any specified timing.
• Only DM Area words can be used for transfer in both the Coordinator
Module and Motion Control Modules.
• Up to 499 words can be transferred.
Data is transferred in the specified direction between the specified DM Area
words in a specified Motion Control Module and the specified DM Area words
in the Coordinator Module when the DM Write Request Bit (A530.00) or DM
Read Request Bit (A530.01) in the Auxiliary Area of the Coordinator Module is
turned ON.
This function is used, for example, to manage data in the Coordinator Module
for use by Motion Control Modules when the data must be backed up.
DM data transfer is possible in PROGRAM, RUN, or MONITOR mode for the
Coordinator Module and Motion Control Modules.
