  1. PI sanitary pressure transmitter
  2. IO-Link benefits

IO-Link provides diagnostic and other data

Keep reading to learn how IO-Link adds more value to PI sanitary pressure transmitters with ceramic capacitive technology. Or, browse our line of PI1 models to find the right one for your application.

Via IO-Link digital communication, the PI family can provide:

High resolution digital process value with 20,000 steps

True digital signal of the process values improve accuracy and resolution due to no A/D conversion losses.

Multiple process values

With IO-Link, process sensors have the ability to transmit multiple sensor values (pressure and temperature) over a single wire.

Device status, diagnostic information, and internal memory

Operating hours, event history, and measuring cell observation available. While the minimum/maximum system pressure and temperature is available via internal memory on the device.

Remote parameterization and optical localization

Calibration offset adjustment and sensor identification via display flashing [IO-L]

Resolution of IO-Link signal

The digital IO-Link communication provides a very stable and accurate signal, which has more immunity to electrical noise than traditional analog communication. The PI1 series also provides precise measurements with exceptionally high resolution. Standard IO-Link architecture with your choice of IO-Link master and the PI1 sensor is all you need to unlock the digital power and diagnostics of this device.

Where can I find more information on sensor IO-Link performance?

More information such as the IO-Link version, cyclical data, and IO-Link resolution can be found under the “Interfaces” section of the data sheet.

Data structure and process values

Diagnostic and other information

Internal Memory

The PI1 series includes instrument and process monitoring indicators that can be used for machine maintenance, sensor health, and process tracking.

  • Hi – Maximum high pressure measured up to max of the IO-Link Measuring Range
  • Lo – Minimum low pressure measured down to min of the IO-Link Measuring Range
  • HIPS – User programmable pressure over limit point
  • HIPC – Pressure over limit counter (Number of times above HIPS limit for at least 0.5 ms)

Switching cycle counter is also available at output 1 and output 2 in the [OUT_Counter] parameter and stores this value every full 60 minutes.

Event Logging

The PI1 series with IO-Link has two logging mechanisms:

  1. Event History (parameter [Event_History]) – records and stores the last 20 events in the onboard sensor memory
  2. Event Counter (parameter [Event_Counter]) – records how often specific events occurred at the sensor

Operating Hours

The PI1 series has an operating hours counter (parameter [operating_hours]) that count the hours the sensor was active. This records automatically and cannot be reset.

Simulation function [SIM]

The sensor can simulate process values and error states. This function provides simple and easy means to test your system and programming without the need for real process values to drive an output. The function works for simulating IO-Link, switching, and analog outputs, removing the need for signal generators.
