Operation cycles of 10 ms, 20 ms, and 50 ms cannot be set for the CS1D-
CPU@@P.
High-speed I/O Refreshing with the CPU Unit Using User Link Tables
User link tables can be set to refresh cycles of 10 ms, 20 ms, or 50 ms, and
the Loop Controller with refresh data with the CPU Unit at the specified cycle.
With this speed, the Loop Controller can quickly (within one cycle time)
refresh contact and analog values.
With the Loop Control Unit, there was a delay of up to 2 cycle times for field
terminal blocks (e.g., Di, Do, Ai, and Ao).
Designate I/O Memory in the CPU Unit Using Registered Tags
User-specified tags and CPU Unit data exchange conditions (such as I/O
memory addresses) can be registered in user link tables on the CX-Process
Tool. The tags registered in a user link table is used to perform data exchange
with the CPU Unit on the specified refresh cycle. In sequence tables and other
function blocks, tags can then be used to specify CPU Unit I/O memory (or bit
or analog I/O values).
User link tables can also be pasted into block diagrams as virtual blocks, or
tags can be automatically registered in the user link table when a field termi-
nal block is pasted.
User link tables provide the same type of functionality as expanded CPU ter-
minals do in Loop Control Units. With the previous method, however, it was
necessary to use expanded CPU terminals or CPU terminals to achieve data
exchange with the CPU Unit, making it necessary to keep track of I/O memory
addresses in the CPU Unit and function block ITEM numbers in expanded
CPU terminals or CPU terminals.
Execute Sequence or Step-progression Control Using Sequence Tables
(CS1W-LCB05 Only)
In process control, the commonly used sequence control operations are often
written in sequence tables. With a LCB@@, you can select either step ladder
programming, the same method used by Loop Control Units, or use sequence
tables, whichever you prefer.
Process progression for step transition (even to other tables), timer/counter
functions, wiring to function block ITEM variables, or comparison operations
using relational expressions are also supported for sequence tables.
Simulated Software Connections between Function Blocks
CX-Process Tool allows you to simulate wiring between function blocks in the
software by joining lines on your computer's screen.
Specify the Order of Operations in Function Block Diagrams
ITEMs can be set in function blocks in block diagrams to specify the order of
processing control and operation blocks. (Blocks are processed left to right
and then top to bottom by default.) With Loop Control Units, operation blocks
were processed first followed by control blocks in the order of block
addresses.
Easily Create a SCADA Interface with the HMI Function
Space for HMI data for control, operation, and external controller blocks is
automatically allocated in the specified bank of the EM area. The bank num-
ber is specified in the System Common block.
With SCADA software, the HMI data in the control, operation, and external
controller blocks can be read and written by specifying the CSV tags.
