Using OPC Server Direct Access
To directly access function blocks from the OPC server, the OPC Server direct
access tags must be output to the SCADA tag file or the RS View tag file. Use the
following procedure to output the OPC Server direct access tags.
1. Select Setting – Option.
2. Select the Enable OPC Server direct access tag option on the General Tab
Page.
3. Select Execute – Create Tag File – CSV Tag or Execute – Create Tag File
– RS View Tag. The SCADA or RS View tag file will be output.
Step 1: Registering Function Blocks to Exchange Data with SCADA Soft-
ware
Loop Control Units: Register Send All Blocks (462) and Receive All Blocks (461)
(and if required, Expanded CPU Unit Terminal and CPU Unit Terminal function
blocks).
LCBjj: Set ITEMS related to HMI functions in the System Common Block
(000) and register tags for user link tables as required.
Loop Control Units: Send All Blocks (462) and Receive All Blocks (461) function
blocks must be registered together. Expanded CPU Unit Terminal and CPU Unit
Terminal function blocks can be registered as required for ITEMs not handled by
Send All Blocks (462) and Receive All Blocks (461) function blocks.
To set CSV tags for an ITEM that cannot be set with the CSV tag settings, regis-
ter the Expanded CPU Unit Terminal or CPU Unit Terminal function blocks and
input/output the ITEM.
Note With Loop Control Units, a CSV tag file cannot be compiled unless
both Send All Blocks (462) and Receive All Blocks (461) function
blocks are registered.
For LCBjj, set System Common Block (000) ITEM 059 (HMI Function Disable
Switch), ITEM 050 (EM Area Bank Allocated for HMI Function), and ITEM 051
(Operation Cycle for HMI Function). To set CSV tags for any other ITEM, register
the tags in the user link table and input/output the ITEM.
Step 2: Setting CSV Tags
Set the CSV tags for each function block as described below. CSV tags can be
set for the following function blocks.
• Loop Control Units: Control blocks, operation blocks (except for Contact
Distributor (201) and default registration TR internal switches), External
