Field
Description
CMInitiator
ActivityTimeoutFactor
The remote device timeout between the Connect response and
receipt of new service requests from the PROFINET Controller.
The IO device application stops this monitoring when IOCR
operations start. This value is fixed at 60.0 seconds.
RedundancyDataHoldTime
The remote device timeout between loss of the Primary AR and
recognition of a new Primary AR. (Loss or Primary AR may occur
when the AR is terminated, or the AR switches to Backup.) If
another AR does not become Primary within this timeout interval,
the IO device aborts all related Backup ARs. This timeout is
used and displayed only when Redundancy Type is “System
Redundancy AR”.
<<< IOCR 0x0001-(Input CR)-
Update Period: 1 ms >>>
0x0001 in this example header represents the IOCR reference
number to uniquely identify the IOCR within the AR.
(Input CR) in this example header is the type of IOCR. The two
possible values are (Input CR) and (Output CR).
Update Period – is the rate at which cyclic IO associated with this
IOCR is updated between the PROFINET Controller and the IO
Device. The Update Period is calculated by multiplying the
SendClk value times the Ratio value.
IOCR
Properties
The binary value of the IOCR Properties field for the AR. The
actual properties are decoded in the indented fields just below
the ARProperties field (MediaRedundancy, RTClass.).
IOCR Tag Header
See PROFINET Application Layer Services for Decentralized
Periphery and Distributed Automation Specification, Version 2.2,
October 2007.
Current Data Status
The data status value from the IOCR. The individual fields of the
status are decoded in the lines below. Station Problem Indicator
can either be Problem detected or Normal operation. Provider
State can either be Stop or Run. Data Valid can either be Invalid
or Valid. State can either be Primary or Backup. For the Input
CR only, Redundancy can either be “Primary Present” or
“Primary Not Present”.
Len
The data length in bytes of the RTC Frame associated with this
IOCR.
FrmId
Contains the identifier of the data within the RTC frame and tells
the producer what frame Id the consumer wants to use when the
RTC data transfer occurs.
SendClk(us)
SendClockTime is the base interval for IOCR timing.
SendClockTime is calculated as: SendClockTime =
SendClockFactor x 31.25. See
PROFINET Application Layer
Services for Decentralized Periphery and Distributed Automation
Specification
, Version 2.2, October 2007, for definition of
SendClockFactor.
Ratio
Reduction Ratio where IOCR Update Period = SendClockTime x
ReductionRatio. See
PROFINET Application Layer Services for
Decentralized Periphery and Distributed Automation
Specification
, Version 2.2, October 2007, for definition of
Reduction Ratio.
