Commissioning Cerabar PMP23 IO-Link Prerequisite The pressure value present is automatically adopted as the zero point. An offset is possible (parallel shifting of the sensor characteristic) to correct the orientation and any zero point drift. The accepted value of the parameter is subtracted from the "raw measured value".
Cerabar PMP23 IO-Link Commissioning Configuring process monitoring For process monitoring, it is possible to specify a pressure range which is monitored by the point level switch. Both monitoring versions are described below. The monitoring function allows the user to define optimum ranges for the process (with high yields etc.) and deploy a point level switch to monitor the ranges.

Description of device parameters Cerabar PMP23 IO-Link Description The simulation affects the process data only. It does not affect the physical switch output. If a simulation is active, a warning to this effect is displayed so that it is obvious to the user that the device is in the simulation mode.
Description of device parameters Cerabar PMP23 IO-Link Prerequisite An offset is possible (parallel shifting of the sensor characteristic) to correct the orientation and any zero point drift. The set value of the parameter is subtracted from the "raw measured value". The requirement to be able to perform a zero point shift without changing the span is met with the offset function.
Cerabar PMP23 IO-Link Description of device parameters Example 1 • Measured value = 0.002 bar (0.029 psi) • Use the Zero point adoption (GTZ) parameter to correct the measured value with the value, e.g. 0.002 bar (0.029 psi). This means that you are assigning the value 0 bar (0 psi) to the pressure present.
Description of device parameters Cerabar PMP23 IO-Link Current output Value for 4 mA (STL) Navigation Parameter → Application → Current output → Value for 4 mA (STL) Description Assignment of the pressure value which should correspond to the 4 mA value.
Cerabar PMP23 IO-Link Description of device parameters Description The pressure value present is automatically adopted for the 4 mA current signal. Parameter for which the current range can be assigned to any section of the nominal range. This occurs by assigning the pressure lower range value to the lower measuring current and the pressure upper range value to the upper measuring current.
