Function Blocks _Et200S_Sixx_Getv24Sig - Siemens ET 200S 1SI Function Manual

The active transfer request can be aborted by setting the reset parameter to TRUE. This will
reset the _ET200S_SIxx_receive FB to its initial state. The receive operation will remain
disabled as long as the signal state at the reset parameter is TRUE.
Status and error display on _ET200S_SIxx_receive
The newDataReceived output parameter indicates that the request has been completed
without errors. The amount of data received is indicated in the dataLength parameter. The
error output indicates that an error has occurred. When an error occurs, the corresponding
event class/number is displayed in the errorID output parameter (see table "Parameter
_ET200S_SIxx_receive"). If no errors have occurred, errorID has a value of "0". The
parameters newDataReceived and error/errorID are also displayed on reset of the
_ET200S_SIxx_receive FB.
Parameters newDataReceived, dataLength, error, and errorID are present for one block pass
only.

Function blocks _ET200S_SIxx_getV24Sig

Task
When an ASCII driver is specified, the _ET200S_SIxx_getV24Sig reads the RS 232C
secondary signals and provides them to the user as output parameters.
Depending on which data interface you have chosen in the hardware configuration, you use
the _ET200S_SI04_getV24Sig function block for the 4-byte data interface, the
_ET200S_SI08_getV24Sig function block for the 8-byte data interface, and the
_ET200S_SI32_getV24Sig function block for the 32-byte data interface of the serial interface
module.
