Function Block Programming
B-3 Operate Function Block
The Operate Function Block facilitates the transmission of aN OPERATE command to a specific temperature
Controller (refer to section 3-3-4 Free Communication Blocks ). The table below lists the specifics of this func-
tion block.
Item
Basic function Sends an Operation command to a specified Temperature Controller via PROFIBUS.
Symbol
Start Trigger
File name PRT1_SCU11_Operate.cxf
Function description Sends an operation command to the CS1/CJ1W-PRM21 PROFIBUS Master I/O addresses allo-
cated to the targeted Temperature Controller, specified by the Unit No. The command is specified
by the command code and related information.
Precautions
EN Input condition Connect EN to an OR between an upwardly differentiated condition for the start trigger and the
BUSY output from the Function Block.
Restrictions on Input • Always use an upwardly differentiated condition for the EN.
variables
• If the Input variables are out of range, the ENO flag will turn OFF and the Function Block will not
be processed.
Restrictions on Out- • This function block requires multiple cycles to process. Always connect an OR including the
put variables BUSY output variable to the EN input variable to ensure that the function block is processed to
completion (see Symbol)
• Do not turn the BUSY output variable ON or OFF outside the function block.
