Programming
4.3 Time-based IO
High-precision input/output with Time-based IO
32
Function Manual, 11/2019, A5E33454822-AC
Functional description
In normal operation, the instruction ensures synchronization of all TIO modules configured at
the HWID input.
The calculated TIO_Time for the instructions of the TIO modules is provided at the
TIO_SYNC_Data output.
Reaction to error
The Error output indicates if the instruction was processed correctly. In the event of an error,
the cause of the error is displayed at the Status output.
Parameter
The table below shows the parameters of the TIO_SYNC instruction.
Parameter Declaration in
library version
Data type Default Description
< V2.0 ≥ V2.0 S7-1500
HWID_1 ...
HWID_8*
Input HW_IO 65535 Hardware identifier for TIO module from hardware
configuration
PIP_Mode* Input PIP 0 Mode for the data update**:
•
0: OIP model with internal update of the process image
by SYNC_PO and SYNC_PI.
• 1: OIP model without internal update of the process
image
•
2: IPO model without internal update of the process
image
PIP_PART* Input USInt 1 Only relevant if PIP_Mode = 0
Number of the process image partition which is to be
updated isochronously.
TIO_SYNC_
Data
Output "TIO_
SYNC_
Data"
Calculated system time for the TIO instructions of the TIO
modules and internal data used for synchronization. See
UDT TIO_SYNC_Data (Page 58).
Status Output DWord 16#0 Status of the instruction: see description of Status
parameter
Error Output Bool False Error = True: An error has occurred. For detailed
information see Status parameter.
Error is reset as soon as the error is corrected.
