Parameter
The table below shows the parameters of the TIO_IOLink_IN instruction.
Parameter
Declaration
Data type
Default
Description
S7-1500
HWID*
Input
HW_IO
0
Hardware identifier for TIO module from HWCN
Port*
Input
USInt
0
Port number (1 to 4) of the connected IO-Link Device
TIO_SYNC_
Data*
Input "TIO_SYNC_
Data"
System time provided for the TIO instructions of the TIO
modules by the TIO_SYNC instruction. See UDT
"TIO_SYNC_Data" (Page 57).
Connect this input parameter with the "TIO_SYNC_Data" output
parameter of the TIO_SYNC instruction.
TO* Input LTime LT#0ns T
o
: Time for output of isochronous output data.
Apply T
o
from the ET 200 station (properties of the PROFINET
interface).
SA_Bit0 Output Bool False Display of a process data change (bit 0 of SA_Data).
SA_Bit0 is event-oriented. As long as no valid time stamp has
been acquired (EventCount = 0), the process data are invalid.
SA_Bit1 Output Bool False Display of a process data change (bit 1 of SA_Data).
SA_Bit1 is event-oriented. As long as no valid time stamp has
been acquired (EventCount = 0), the process data are invalid.
SA_Data
Output
DWord
16#0
Process data SA_Data (Sensor Application Data)
TimeStamp Output LTime LT#0ns Time stamp: Time when a change of the process signal SA-
Data took place at the IO-Link Device.
EventCount Output UInt 0 Counter: Is incremented with each new, valid time stamp. The
counter is reset with each CPU startup.
Status
Output
DWord
16#0
Status of the instruction: see description of Status parameter
Error Output Bool False If True, this output indicates that an error has occurred. For
detailed information see Status parameter.
Error is reset as soon as the error is remedied.
* Checked once at startup of the CPU
