11.4 Functional Safety Functions

HW1485509
HW1485509
When performing a setting as marked with the red square, the condition of
signal 1 line is defined as satisfied. because “ON” is set to {Condition} at
the input signal {MSOUT01}, and
(=ON)} is set to {Status}.
Up to 5 signals can be set to a setting (up to 4 for the tool change monitor
function).
Conditions of the lines from signal 1 line to signal 5 line are judged by the
safety input signal respectively, the setting is enabled only when all the
conditions are satisfied.
The line “----” (undefined) is disregarded for this judgement
Based on above mentioned judging methods, settings can be enabled/
disabled by the multi signals.
For example, there are following methods when Enable/Disable settings
by 3 signals (MSOUT1, MSOUT2, MSOUT3).
Example 1: Switching one file using 1 signal
Enable/Disable the setting individually by one signal.
There can be a time difference after the first signal and
before the last signal. In the functional safety function, an
interval of 32 [ms] is equipped to the system to be totally
switched to internally settled after the last signal change.
For this reason, please take this into consideration when
performing the following operations.
• When switching several signals, do not take more than
32 [ms].
– The signals may be settled with half-specified values.
• Do not use signals that continue shifting ON/OFF within
the interval of less than 32 [ms].
– Signals will not be settled.
