Standard Function Blocks
•
VTyp:
Type of valve to be monitored
VTyp = 0:
Monitoring a directional control valve
VTyp = 1:
Monitoring a poppet valve
(see also under “Function”)
•
RSET:
Error reset
RSET = 0/1 pulse edge: Reset fault
It will only be possible to reset an existing fault if
the valve is in its start (off) position (valve de-
energised and acknowledgement from valve is
present) and no start signal is present (
ON •1).
Output parameters
•
ENBL:
Enable flag bit
ENBL = 0: Enable locked
When the valves are switched off (input parameter
ON = 1/0 pulse edge), the enable is locked until
the valves return to their start position (input
parameter
S1 = 1 and S2 = 1). This is not an error.
The block will cancel the enable immediately if it
detects a fault.
ENBL = 1: Enable
The block will set the enable if no fault has been
found and the valves are either in operation or in
their start position.
•
Y1:
Output parameters for operating valve Y1
Y1 = 0:
Valve Y1 off
Y1 = 1:
Valve Y1 on
•
Y2:
Output parameter for operating valve Y2
Y2 = 0:
Valve Y2 off
Y2 = 1:
Valve Y2 on
•
ERR:
This output parameter is set as soon as a fault is discovered.
ERR = 0:
No fault found
ERR = 1:
Fault found
