Appendix 1 Precautions for Accessing Redundant CPU System
This section explains precautions for accessing a redundant CPU system using the CC-
Link IE Controller Network board.
Access to redundant CPU system
(1) Redundant CPU specification
When the system (control system, standby system, system A, system B) of the
Redundant CPU is specified to access the Redundant CPU, the Logical station No.
set on the "Target setting" screen of the CC IE Control utility is used for access.
For the Logical station No. setting, refer to the following section.
Section 8.4.8 Target setting screen
POINT
When a CC-Link IE Controller Network board with a serial number whose first five
digits are 10091 or lower, or an SW1DNC-MNETG-B with the software version
1.04E or earlier is used, the redundant CPU system cannot be accessed directly
with the CC-Link IE Controller Network interface board.
Relay the MELSECNET/H network system to access the redundant CPU system.
