Omron CX-INTEGRATOR - V1.1 Operation Manual page 18

• Because the devices are reset in order, communications errors will
temporarily occur in the master and slaves. For this reason, do not
download the network configuration while the master-side PLC (CPU Unit)
is operating.
• When downloading the network configuration, each of the devices is reset.
If the Master Unit is reset first, it may cause errors in writing parameters to
the subsequent slaves. For that reason, this method (downloading the
network configuration) should be used only when the Master Unit has been
given the highest address.
• Downloaded device parameters will be valid only after the devices are reset
unless they are the OMRON CVM1-DRM21-V1, C200HW-DRM21-V1,
CS1W-DRM21(-V1), or CJ1W-DRM21.
• When the devices are reset, communications errors will temporarily occur.
For this reason, do not reset the devices while the master-side PLC (CPU
Unit) is operating.
Data Links in Controller Link or SYSMAC LINK Networks
• The data link mode (manual setting or automatic setting) and data link
method are determined according to the data link setting in the startup node.
In the startup node, set a data link table for manual settings and data link
automatic setting parameters for automatic settings. If the settings are
incorrect, the data links will not start.
Check the following items before starting data links.
(1) Manually Set Data Links
Check the data link tables in each node participating in the data link to
see that they are correct.
Be sure that data link tables are deleted from nodes that are not
participating in the data links.
(2) Automatically Set Data Links
Be sure that the correct DM parameters have been set in the data link
startup node.
• If incorrect data link tables or parameters are set, injury may result due to
unexpected operation of the system. Even if the correct data link tables and
parameters have been set, do not start or stop data links before verifying
that there will be no adverse influence on the system.
Routing Tables
CPU Bus Units are reset when routing tables are transferred from a
Programming Device to a PLC to allow set routing tables to be read. Make
sure that resetting CPU Bus Units will not cause equipment damage or
dangerous system behavior before transferring tables.
