Designator / Data type Info / Setting options

The address must be transferred with the ADR operator.

Example: "… pbyData_address:=ADR(%MB0) , …"

wLength_of_telegram / WORD Number of bytes to be transmitted starting from the start address

"pbyData_address". The valid length is between 1 and 1024 bytes.

wNumber_of_IOBytes / WORD Number of bytes available in the process image. The valid values

depend on the bus system used and the module configuration:

CAN: 8 bytes

Profibus: 8, 16, 32, 60 bytes

EtherCat: 60 bytes

Outputs (VAR_OUT)

Designator / Data type Value / Meaning

xDone / BOOL The bit is set if a transmit request or a reset has been executed

correctly.

xBusy / BOOL The bit is set as long as a request (transmit/reset) is being processed.

After the processing has been completed or if an error occurs, the bit

is reset and xDone or xError is set.

xError / BOOL The bit is set if an error occurs. "wStatus" provides detailed

information about the error.

wStatus / WORD No error (xError not set):

0x0000: no request being processed / request executed correctly

0x8181: transmit request being processed

Error ("xError" set):

0x0202: invalid value for wNumber_of_IOBytes

0x0517: invalid value for wLength_of_telegram

0x070A: transmission failed

0x0301: no addresses transferred (pbyInput_address, pbyOut-

put_address, pbyData_address)

Note: Pointers to wrong addresses or to data areas with insufficient length can

cause program errors or even a crash of the PLC!
