x = 1 ... 8
Input
Data type
Value/meaning
TPx_bEnablePosEdge
BOOL
Enable response to rising edge
Note:
• If several positive edges occur within the basic cycle time (HighLine: 1 ms), only
the first positive edge initiates the touch probe event and no status signal "touch
probe(s) lost" are generated.
TRUE A touch probe event is activated by a positive edge at the digital
input DIx.
TPx_bEnableNegEdge
BOOL
Enable response to negative edge
Note:
• If several negative edges occur within the basic cycle time (HighLine: 1 ms), only
the first negative edge initiates the touch probe event.
• If a positive and negative edge occur within the basic cycle time (1 ms) and if the
response to both edges is enabled, only the positive edge initiates the touch
probe event.
• In both cases no status signal "touch probe(s) lost" is generated.
TRUE A touch probe event is activated by a negative edge at the digital
input DIx.
Output
Data type
Value/meaning
TPx_dnTouchProbeTimeLag
DINT

• 1 ms ≡ 20 bits
TPx_bTouchProbeReceived
BOOL
Status signal "Touch probe detected"
• Status is only set for one task cycle.
TRUE Touch probe event has been activated.
TPx_bTouchProbeLost
BOOL
Status signal "Touch probe(s) lost"
• Status is only set for one task cycle.
