Name P type
1)
error OUT BOOL
errorID OUT WORD
Parameter types: IN = input parameter, OUT = output parameter, IN/OUT = in/out parameter
1)
Note: The periOut parameter must be provided with an array of type ARRAY [0..3] of BYTE or ARRAY [0..7] of BYTE.
2)
Create a local or global array in your program under VAR (do not create a temporary array under VAR_TEMP). After the
FB has been called, this array must be assigned to the I/O variable for the I/O outputs of the module. See call example in
chapter "Calling the function blocks"!
For error information, refer to SIMATIC manuals

Task integration (call)
The _ET200S_SIxx_flowRts FB must be called cyclically in the BackgroundTask or the
TimerInterruptTask. Calling in the SystemInterruptTask is not permitted. Calling the function
block in the IPOSynchronousTask is not recommended for runtime reasons.

Task
The _ET200S_SIxx_flowV24 function block enables you to modify parameters on the module
independently of the parameter assignment interface if the "Automatic use of V24 signal" data
flow control has been specified for the module.
Depending on which data interface you have chosen in the hardware configuration, you use
the _ET200S_SI04_flowV24 function block for the 4-byte data interface, the
_ET200S_SI08_flowV24 function block for the 8-byte data interface, and the
_ET200S_SI32_flowV24 function block for the 32-byte data interface of the serial interface
module.
