z Operation
With the CX-Programmer, open the PLC Setup's FINS Protection Tab and select the Validate FINS
write protection via network Option. When this option is selected, it will not be possible to execute
write operations for that CPU Unit with FINS commands sent through a network (except a direct
serial connection). To permit write operations from particular nodes, enter network addresses and
node addresses for the node under Nodes excluded from protection targets. (Up to 32 nodes can be
excluded from FINS Write Protection).
