Online Network Connections without I/O Tables

Summary
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 • Changing the Operating Mode
allowed through the
• Transferring the ladder program to the CPU Unit
network when FINS
• Transferring parameter area data (PLC Setup, I/O table, and
write protection is
CPU Bus Unit Setup) to the CPU Unit
enabled.
• 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.
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.
