6-150 Modular Block System: Hydraulic Presses
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 position (valve de-energised
and acknowledgement from valve is present) and
no start signal is present (
Y1On = 0, Y2On = 0).
Output parameters
• ENBL: Enable flag bit
ENBL = 0: Enable locked
When the valve is switched off (input parameter
Y1On / Y2On = 1/0 pulse edge), the enable is
locked until the valve returns to its start position
(input parameter
S1 = 1 / 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 parameters for operating valve Y2
Y2 = 0:
Valve Y2 off
Y2 = 1: Valve Y2 on
• ERR: The output parameter is set as soon as a fault is detected.
ERR = 0:
No fault detected
ERR = 1: Fault detected
