From the function table to the logic diagram

Creating a logic diagram
In the next step, a simple logic diagram is made from the function table. The fail-safe inputs
of the TM54F must be connected and this diagram serves as the basis for this.
The logic diagram has a few functions that are not listed in the function table:
● Emergency stop is executed with SS1.
● In order to acknowledge SI alarms, a safe input as acknowledgment is necessary.
● Only SLS2 and SLS4 are used for SLS.
SLS1 active
SLS2 active
SLS3 active
SLS4 active
SLS selection bit 0 is set permanently to "1" when configuring the TM54F, i.e. "Statically
inactive" in STARTER. The inputs for the TM54F can be assigned as follows:
Input
F-DI 0
F-DI 1
F-DI 2
F-DI 3
