RUN (channel passivation and reintegration)
PROFIsafe communication is up and running. The safe application is running with detected channel errors.
Channel error (e.g., no expected test pulses, discrepancy time, etc.) is identified in at least one of channels.
The fail-safe value ("0") is transferred to the PROFIsafe F-Host for the passivated input channel(s). The
related PROFIsafe diagnostic bit(s) are also set to "0" to indicate the usage of fail-safe values.
A passivated output channel has a state of "0" and the related PROFIsafe diagnostic bit(s) are also set to "0"
to indicate the usage of fail-safe values.
As soon as the channel error is gone (e.g., wiring error was corrected; this is valid only for those errors which
are acknowledgeable), the reintegration request bit for the given channel switches to "1", which indicates the
safety application running on the Safety CPU that a reintegration of the channel is possible. Setting the
acknowledge reintegration bit from "0" to "1" initiates a reintegration of the given channel. A positive edge
from "0" to "1" is required to acknowledge channel reintegration.
As soon as all channel errors are gone and acknowledged, the RUN (ok) state is reached.
PROFIsafe status bits in the F-Host for Safety I/O module:
OA_Req_S = 0
FV_activated_S = 0
Device_Fault = 0
Process data bits in the Safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0 if an error is still present; 1 if the channel can be reintegrated.
