IndraControl S20 Module With Safe Digital Inputs S20-PSDI-8/4
The individual input pairs of a module can be parameterized differently, which
means that different safety integrity levels (SIL, SILCL, Cat., PL) can be achieved.
The fixed assignment for two-channel operation of the inputs is as follows:
•
IN0_Ch1 to IN0_Ch2
•
IN1_Ch1 to IN1_Ch2
•
IN2_Ch1 to IN2_Ch2
•
IN3_Ch1 to IN3_Ch2
The input information of both inputs is mapped to one bit. The unused bits are al-
ways set to "0".
For single-channel assignment, the inputs can be parameterized so that they op-
erate independently of one another.
The safe inputs are parameterized in pairs for each connector.

Remark
Parameterize the input pairs in pairs.
For unused inputs, the data is filled with "0".
In two-channel operation, the inputs have a fixed assign-
ment to one another.
The filter time is used to suppress interference for the input
signals.
Select the filter time so that the duration of the input signal is
greater than the filter time.
The filter time affects the response time of the
safety function.
Parameterization is only active if the input is parameterized
for two-channel operation.
