Whenever a fault is diagnosed in the input information for the
module, the reaction depends on the module operating mode
selected:
– With the operating mode "Module-based passivation"
(PAA byte 0, bit 1 = 0) that module passivation is per­
formed in accordance with the PROFIsafe specification.
– With the "Channel-wise passivation" operating mode
(PAA byte 0, bit 1 = 1) the affected channel bits (Ex, Qx) in
the input image (PAE bytes 0 and 1) are set to logical
zero.
With a diagnosed internal module error, module passivation
is based on the PROFIsafe specification.
In the event of a massive stochastic failure of the module
hardware, the system responds with a PROFIsafe timeout.
The input module can be used for the following tasks:
– Connection of different switches and sensors to the safety
chain
– Use of multi-channel sensor applications with up to 8 se­
cure inputs, groupable and suitable for configuration with
the help of 11 different function modes
– Use as an input module for a primary safety controller.
Several input modules can be used together and these
monitor mutually independent sensors.
The following overview constitutes a selection and lists some
but not all possible applications.
