Do not allow the area to which user link table data is written to overlap with any
other area used by the CPU Unit or other Units. If areas overlap, the system may
operate in an unexpected manner, which may result in injury.
When using a user link table to write bit data to I/O memory in the CPU Unit.
Never allow ladder programming or communications processes in the CPU Unit
to write to any bits in the words in which bits are written from a user link table.
Depending on the timing, any attempts to write to these words from ladder
programming or communications processes may be ignored.
Example: If tag A in a user link table writes to bit 00 of W000 and an OUT
instruction in the ladder program in the CPU Unit write to bit 01 of W000, the write
from the ladder program may be ignored.
Confirm the status of connected devices before transferring the setting for the
MV tight shut function and MV analog output reverse function to the Loop Con-
troller. Devices and equipment may perform unexpected operations if the data
destination is mistaken.
Use one of the following methods to create a user link table.
• Method 1: Registration on the User Link Table Edit Screen
• Method 2: Registration from the Block Diagram
• Method 3: Batch registration on the User Link Table Edit Screen
• Method 4: Automatic Registration when Pasting Field Terminal Block and
Creating Software Connections
1. Method 1: Registration on the User Link Table Edit Screen
1) Select Edit/User Link Table from the Settings Menu.
2) Right-click on the User Link Table Edit Screen and select Add from the
pop-up menu.
2. Method 2: Registration from the Block Diagram
1) Right-click on the block diagram and select Register/User Link Table/
Link Input (Read from CPU Memory) or Register/User Link Table/
Link Output (Write to CPU Memory) from the pop-up menu. A user link
table block will be created.
2) Select the block that was created, right-click, and select Register/User
Link Table/Register Block Cell from the pop-up menu.
