Configuration of Function Blocks
Connecting analog signals (variables) and accumulated value signals
Example
Connecting contact signals
Specify in the analog input ITEMs which analog output ITEM and its block
address are to be used to introduce analog signal function blocks on the
input side.
To introduce ITEM006 (PV) of the Basic PID block of block address 001 from
ITEM011 (Y1) of the Square Root block of block address 100.
Block address: 100
Square Root
011
Note Connection of analog signals or accumulated value signals can be executed
on CX-Process Tool separately from setting of ITEM data as wiring of
function blocks. (Connection of analog signals or accumulated value signals
can also be set as ITEM data.)
Contact signals are connected via the Step Ladder Program block (Block
Model 301) or the Contact Distributor Block (Block Model 201). *1
Specify both contact inputs (Step Ladder Program block or Contact
Distributor block to specified function block) and contact outputs (specified
function block to Step Ladder Program block or Contact Distributor block) in
the Step Ladder Program block (Block Model 301) or the Contact Distributor
Block (Block Model 201). Do not specify these contact signals to ITEMs in
the specified function block.
Note On CX-Process Tool, connection of contact signals is executed at setting of
ITEM data.
Â
1: As an exception, with some of the ITEMs (PV error input of ITEM018
and MV error input of ITEM090 of the Basic PID block or the Advanced
PID block) contacts are input specified as the source designation.
