19.2.2 Other representation variants
In addition to the above, there are also the following variants for representing the
diagnostics:
•
Safety code sequence:
Sending of the code sequence, with no evaluation of the data; the current
state is sent for each bit. Sending of a code sequence for safety input slaves
results in a continuous changing between states "1" and "0".
• Substitution values:
Substitution of the code sequences by the state of the input (Safe Subst
Val), where the following values are sent:
19.2.3 Changing the default setting
The diagnostics type is set or changed using the device display (Safety -> AS-i
Safety -> Safe subst Val)
Another method for setting the diagnostics type is by using the GSD/GSDML pa-
rameters:
Old GSD files do not affect the setting; new GSDs do not change the mode by de-
fault (default setting: "no change"):
