Omron CS1W-LC001 Operation Manual page 6

New Version Features: Ver. 2.0 to Ver.2.5
x
The following features had been added to the CS1W-LC001 Loop Control
Unit in upgrading from version 2.0 to version 2.5.
New Function Blocks
The following function blocks have been added: Fuzzy Logic (Block Model
016), Range Conversion (Block Model 127), Ramped Switch (Block Model
167), Level Check (Block Model 210), Ai4 Terminal (DRT1-AD04) (Block
Model 588), and Ao2Terminal (DRT1-DA02) (Block Model 589).
Notifying the CPU Unit of Function Block Changes
The CPU Unit can be informed when function blocks are downloaded by
block from the CX-Process Tool software to the Loop Control Unit. (See
note.)
*1: Similar to online editing for the Loop Control Unit.
Notification is achieved by monitoring the Function Block Change Flag (bit
15 in word n) allocated to the Loop Control Unit as a CPU Bus Unit.
Changes in the status of this flag can be used to trigger required
processing, such as notification that function blocks have changed.
Operation Specifications for Contact Type Control Target Operation
Blocks when Changing from AUTO to MAN or from Site to Central
Operation
For the ON/OFF Valve Manipulator block (Block Model 221), Motor
Manipulator block (Block Model 222), Reversible Motor Manipulator block
(Block Model 223), and Motor Opening Manipulator block (Block Model
224) only MAN status was switched to previously, but now the MAN input
is made to agree with the AUTO input to enter MAN status.
Also when the Site Manipulation Switch was changed from site to central
for these blocks, only operation was changed to the site, but now the
status is changed to MAN and the MAN input is made to agree with the
answer (feedback) input to switch to maintain status at the site while
allowing central operation.
Shorter I/O Refresh Cycle for Analog I/O Units
Although previously the external I/O refresh cycle for Mixed Analog I/O
Units was one cycle longer for Ai/Ao Terminals, specifications have been
changed so that the additional cycle is no longer required.
A Periodic Initialization Function Added to the Receive All Blocks
block (Block Model 461)
ITEM 030 (periodic initialization) and ITEM 031 (initialization interval) have
been added to the Receive All Blocks block (Block Model 461). These
ITEMs can be used to periodically initialize function block ITEM data in the
I/O memory of the CPU Unit.
ITEM Additions and Specification Changes for Other Blocks
Á
A Block Registration Flag (ITEM 039) and the Tool Version (ITEM 110)
have been added to the System Common block (Block Model 000).
Á
A Warning Limit (ITEM 012) has been added to the Basic PID block
(Block Model 011, Advanced PID block (Block Model 020), 2-Position
ON/OFF block (Block Model 001), 3-Position ON/OFF block (Block Model
002), Indication and Setting block (Block Model 031), Indication and
Operation block (Block Model 032), Ratio Setting block (Block Model
