Bit 1 = 0: Only send an output diagnostic message if the
output is being controlled. A check is not done to see which
solenoids are available when the system is switched on. If
an output is being controlled where there is no solenoid, a
diagnostic message will be generated.
Bit 1 = 1: A check is done once to see which solenoids are
available when the system is switched on. This information
is transferred to the controller via a diagnostic message.
This message can be compared with a stored system
configuration in the controller. (This function is only
supported with Profibus DP, the diagnostic data is cyclically
transferred in other fieldbus systems.)
Missing solenoids can be determined when the system is
switched on. In cyclical operation, diagnostic messages are
only sent if there have been any changes. "Open load" is
reported immediately and the valve does not have to be
controlled.
