The valve spool position is returned on all Bosch valves. The message "Valve
spool is not responding" is output if the valve spool position exits the tolerance
field of 10 % of maximum stroke around the setpoint for longer than the time set
in MD 5614 when the power is enabled. This error message cannot be output if
no checkback signal is configured for the valve spool position (MD 5530).
Input bit field for controlling the variable signalling function.
Minimum: Maximum:
0 7
Note
Bit 1 is effective only if signal number 0 is selected in MD 5621: PROG_SIG-
NAL_NR.
A random memory location from address space X or Y in the data RAM is moni-
tored for violation of a parameterizable threshold for the variable signalling func-
tion. A tolerance band can be set around this threshold; this is taken into ac-
count when the threshold is scanned for violation in either direction. Any
violation of the tolerance band is signalled to the PLC. This violation message
can be linked to a pickup and/or dropout delay. The signalling function operates
in a 4 ms cycle.
