Complementary information
The testing of the logic program is not a safety test.
7.6.8
Logic execution time
Logic execution time
The logic execution time is the time required to execute one logic cycle.
The logic execution time depends on the type and number of function blocks used. It is
a multiple of 4 ms.
The status of the safety controller outputs only changes at the end of a logic cycle. A
change in the status of the safety controller inputs only becomes effective at the start
of the next logic cycle.
Complementary information
The configuration software displays both the logic execution time as well as the per‐
centage of this time that has actually been used under
FB group info
in the logic editor.
If the amount of time used exceeds 100% of the logic execution time, then the logic
execution time is automatically increased by 4 ms.
The logic execution time has an accuracy of ± 500 ppm (parts per million).
7.6.9
I/O matrix
The
I/O matrix
tab in the worksheet shows which inputs affect which outputs. You can
use the I/O matrix, for example, to check whether the logic program is complete.
•
Green field: Input affects output.
•
White field: There is no relationship between input and output.
The
I/O matrix
selection window lists all inputs and outputs in the CPU logic catalog.
Activated inputs and outputs are displayed in the matrix.
7.6.10
I/O summary page
The I/O summary page summarizes all logic pages into a single overview:
•
On the left, the input elements of a logic page
•
In the middle, the function blocks combined into a block
•
On the right, the output elements of a logic page
7.6.11
Logic access protection
Overview
The logic access protection prevents changing and optionally viewing of the individual
logic pages by unauthorized persons.
