Note: The rapid digital inputs have to be assigned to the parameters

S-0-0401 and S-0-0402 (default setting of P-0-0300, Digital

I/Os, assignment list etc.)!

See "Digital Inputs/Outputs" in the same chapter

A switching edge at the probe input can trigger the detection of a

measured value. Switching edges, however, only cause a measured

value to be detected when the following requirements have been fulfilled:

• The presetting for measured value detection with positive and/or

negative switching edge at the respective probe input was activated in

S-0-0169, Probe control parameter.

• The measured value detection was started via S-0-0170, Probing

cycle procedure command.

• The respective probe input for measured value detection was enabled

(S-0-0405, Probe 1 enable or S-0-0405, Probe 2 enable).

In parameter S-0-0169, Probe control parameter it is possible to set,

separately for probe 1 and 2, in which mode the measurement is to take

place. The measured value detection must have been activated.

The following enable modes are possible:

• Single measurement

After the respective probe has been enabled (S-0-0405 or S-0-0406) a

value is only detected at the first measured value trigger. Before every

other measurement a repeated probe enable is required!

• Continuous measurement

After the respective probe has been enabled (S-0-0405 or S-0-0406) a

new measured value is detected at each measured value trigger.
