OMRON CJ1W-PTS52  Process Simulation I/O Module

Operations from CX-Programmer (including CX-Net) through the Network

The following CX-Programmer (including CX-Net) operations are restricted by

FINS write protection when performed on the CPU Unit through the network.

Operations not

allowed through the

network when FINS

write protection is

enabled.

• Changing the Operating Mode

• Transferring the ladder program to the CPU Unit

• Transferring parameter area data (PLC Setup, I/O table, and

CPU Bus Unit Setup) to the CPU Unit

• Transferring memory area data (I/O memory data) to the

CPU Unit

• Transferring the variable table, comments, or program index

to the CPU Unit

• Forced Set/Reset

• Changing timer/counter set values

• Online editing

• Writing file memory

• Clearing the error log

• Setting the clock

• Releasing the access right

• Transferring the routing table

• Transferring the data link table​

1. FINS write protection does not prevent CX-Programmer operations from a

computer connected through a direct serial connection.

2. FINS write protection does not prevent the following file memory write op

erations.

• Automatic transfer from the Memory Card at startup

• Simple backup function (including backup operations to selected

Units/Boards)

• Writing files with the FWRIT (WRITE DATA FILE) instruction

Operations from Other Support Software

FINS write protection also prevents the following operations performed

through the network by the CX-Protocol and CX-Process.

• Changing the CPU Unit’s operating mode, writing memory areas,

transferring PLC Setup settings, transferring the I/O table, forced set/

reset, and clearing the CPU Unit’s error log

Operations from Applications That Use FinsGateway

FINS write protection prevents all write operations addressed to the CPU Unit

from applications that use FinsGateway, such as PLC Reporter and Compo

let.

1-6-4 Online Network Connections without I/O Tables

Summary

With CJ-series CPU Units, the CPU Unit can recognize a CPU Bus Unit (such

as a Network Communications Unit, see note) even if the I/O tables have not

been created and there is no registered I/O tables as a result of using auto

matic I/O allocation at startup.
