FINS Protection
Settings for FINS Write Protection via Network
Validate FINS Write Protection via Network
This parameter determines whether write protection is used for FINS commands over a network.
This parameter is used to prevent accidentally writing memory via a network connected with a con-
nection other than a serial connection. If this parameter is enabled, writing will be possible only from
nodes set for the Nodes excluded from protection targets parameter.
Parameter

Nodes Excluded from Protection Targets
Set the nodes for which writing will be enabled even when protection is enabled.
Set the nodes and networks from which FINS write operations will be enabled even when protection
is enabled. The total number of nodes set to be excluded from write protection will be automatically
set.
A maximum of 32 nodes can be set. If these settings are not made (i.e., if the total number of nodes
is 0), write operations will be disabled for all nodes but the local node

Questions and answers
How do I retrieve fault codes from plc: CJ2M-CPU35
To retrieve fault codes from an Omron CJ2M-CPU35 PLC, use the following method:
1. Go online with the PLC using either:
- The known device and CPU type via the "Change PLC" dialog box, or
- Auto Online if the device and CPU type are unknown but connected via serial line.
2. Once online, select the menu option: PLC → Edit → Information.
3. This opens the PLC Information Dialog Box, where you can view information such as fault codes and unit version.
Additionally, check the Battery Error Flag (A402.04) and the ERR/ALM indicator on the CPU Unit, which may signal errors like low battery.
