3.2.1Calculating the pressure

Devices with metallic process isolating diaphragm

The process pressure deflects the metal process isolating diaphragm of the sensor and a fill fluid transfers the pressure to a Wheatstone bridge (semiconductor technology). The pressure-dependent change in the bridge output voltage is measured and evaluated.

Installation	Cerabar PMP23 IO-Link

5Installation

5.1Mounting dimensions

For dimensions, see the "Mechanical construction" section in the Technical Information.

5.2Installation conditions

•Moisture must not penetrate the housing when mounting the device, establishing the electrical connection and during operation.

•For M12 plug made of metal: Do not remove the protection cap (only in IP69) of M12 plug connection until shortly before electrical connection.

•Do not clean or touch process isolating diaphragms with hard and/or pointed objects.

•Do not remove process isolating diaphragm protection until shortly before installation.

•Always tighten the cable entry firmly.

•Point the cable and connector downwards where possible to prevent moisture from entering (e.g. rain or condensation water).

•Protect housing against impact.

•For devices with gauge pressure sensor, the following applies:

NOTICE

If a heated device is cooled in the course of a cleaning process (by cold water, for example), a vacuum develops for a short time causing moisture to penetrate the sensor via the pressure compensation element (1).

Device could be destroyed!

In the event of this happening, mount the device in such a way that the pressure compensation element (1) is pointing downwards at an angle or to the side, if possible.

6.4Post-connection check

Is the device or cable undamaged (visual check)?

Do the cables comply with the requirements?

Do the mounted cables have adequate strain relief?

Are all the cable glands installed, firmly tightened and leak-tight?

Does the supply voltage match the specifications on the nameplate?

1)100 mA can be guaranteed over the entire temperature range for the switch output 1 x PNP + 4 to 20 mA output. For lower ambient temperatures, higher currents are possible but cannot be guaranteed. Typical value at 20 °C (68 °F) approx. 200 mA. 200 mA can be guaranteed over the entire temperature range for the "1 x PNP" switch output.

2)Larger currents are supported, thus deviating from the IO-Link standard.

7.1Operation with an operating menu

7.1.1IO-Link

IO-Link information

IO-Link is a point-to-point connection for communication between the measuring device and an IO-Link master. The measuring device features an IO-Link communication interface type 2 with a second IO function on pin 4. This requires an IO-Link-compatible assembly (IO-Link master) for operation. The IO-Link communication interface enables direct access to the process and diagnostic data. It also provides the option of configuring the measuring device while in operation.

Physical layer, the measuring device supports the following features:

•IO-Link specification: version 1.1

8.1Process data

The measuring device has a current output and a switch output. The status of the switch output is transmitted in the form of process data via IO-Link.

•In the SIO mode, switch output 1 is switched at pin 4 of the M12 plug. In the IO-Link communication mode, this pin is reserved exclusively for communication.

•The current output at pin 2 of the M12 plug is always active or can be optionally deactivated via IO-Link.

•The device's process data are transmitted cyclically in 32-bit chunks.

Bit	0 (LSB)	1	...	28	29 (MSB)	30	31
Measuring device	Pressure value					OU1	res.

Bit 31 is reserved. Bit 30 provides the status of the switch output.

Here, 1 or DC 24 V corresponds to the logical "closed" state on the switch output. The remaining 30 bits contain the analog raw measured value of the device. This value has yet to be scaled by the target system to the nominal operating range of the existing measuring device.

Bit	Process value	Value range
30	OU1	0	= open
		1	= closed
0 to 29	Raw value	Int30

The decimal separator must be set with a gradient. The gradients depend on the unit in question. The following units are available:

•bar: 0.0001

•kPa: 0.01

•MPa: 0.00001

•psi: 0.001

Examples:

Pressure value	Transmitted	Scaled with gradient
–320 mbar	–3 200	–0.32
22 bar	220 000	22
133 Pa	13 300	133
665 psi	665 000	665
399.5 bar	3 995 000	399.5

8.2Reading out and writing device data (ISDU – Indexed Service Data Unit)

Device data are always exchanged acyclically and at the request of the IO-Link master.

Using the device data, the following parameter values or device statuses can be read out:
