Through the input image, in addition to the current status,
the module signals the channel error status to the controller
(
Tab. 1/8, channel error status).
Input data The output module in byte 0 returns the logical actual
statuses as well as the statuses of the monitoring flags as
input data to the F-Host (
Tab. 1/8). This enables control
of the status of the monitoring flag.
In byte 1, setting of the parameter “channel-wise passivation”
can be returned. If channel-wise passivation is switched on,
through the bits “Channel fault status channel ... ” are
signaled the channel errors detected by the module. These
can be evaluated by the F-Host.

1) These bits return the logical actual statuses. The statuses are not determined through
measurements. No external voltages are evaluated at passivated or switched-off outputs. In case
of passivation of the complete module, these bits supply 0-signals. In case of passivation of an
output channel, the corresponding bit supplies a logic 0.
