Module Parameters - General; Module Parameters - Safe Inputs - Siemens SIMATIC ET 200SP Manual

Assigning parameters / Setting the address space
6.2 Explanation of the parameters
With STEP 7 (classic) the F-CM AS-i Safety module is configured independently of the
configuration of the module inserted on the left (as a rule: CM AS-i Master ST).
Connection of the BaseUnit only to safety extra-low voltage with limiting of output voltage to
max. 40 V under fault condition
Connect the BaseUnit only to AS-i power supply units that meet the requirements named in
Section Terminal assignment (Page 27), "Power supply units for AS-Interface". Connection
to higher voltage may result in death, severe injury, and serious property damage.
6.2.3

Module parameters - General

Behavior after channel faults
This parameter is permanently set to "Passivate the channel".
After channel faults have occurred, only the faulty PROFIsafe channels are passivated. The
PROFIsafe channel corresponds to the safe input and output address in the process image.
6.2.4

Module parameters - Safe inputs

Configuration status
A valid evaluation is only possible if a compatible safe AS-i slave is actively operating on the
network.
Input monitoring where there is a missing safe input or a missing AS-i slave causes a
passivation of the input address. If no configuration of the slaves is saved in the STEP 7
project, the settings of the AS-i master must ensure that the connected compatible safe AS-i
slave is actively operating, for example, using the "SET" button of the master.
Input monitoring activated
With activation of the input monitoring, you activate the corresponding AS-i slave as an input
channel for signal processing in the safety program. The AS-i address must be assigned to a
safe AS-i input slave.
When the input monitoring is activated, the value of the input channel is calculated based on
the input states of the assigned safe AS-i input slave and the evaluation conditions specified
by the parameter assignment. If a fault occurs, the substitute value "0" is transferred and the
channel is passivated.
