4.3 Time-based IO
High-precision input/output with Time-based IO
Function Manual, 08/2014, A5E33454822-AB
35
The table below shows the parameters of the TIO_SYNC instruction.
HWID_1 ...
Input HW_IO -1 Hardware identifier for TIO module from HWCN
SendClock* Input LTime LT#0ns Send clock of the sync domain.
Apply the send clock from the PROFINET configuration.
PIP_Mode* Input USInt 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
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 57).
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
** The IPO model (PIP_Mode = 2
) provides the shortest response times, but it also places the highest demands on system
performance. Processing of all TIO instructions and other program sections must be completed within one send clock.
