Commissioning
8.1
Function check
Perform the following checks prior to commissioning the measuring point:
1. Perform the post-mounting check using the checklist.
2. Perform the post-connection check using the checklist.
8.2
Switching on the device
During the switch-on procedure, the transmitter runs through internal test functions. The
following sequence of messages appears on the display:
Step Indication
1
Text "Display" and firmware version of the display
2
Device name with firmware, hardware version and the IO-Link device ID in hexadecimal format
3
Information on the sensor configuration (sensor element and type of connection)
4
Displays the switch points
5a
Current measured value or
5b
Current status message
If the switch-on procedure is not successful, the relevant diagnostic event is displayed, depending
on the cause. For a detailed list of diagnostic events and the corresponding troubleshooting
instructions, see the "Diagnostics and troubleshooting" section.
The device works after approx. 5 seconds. Normal measuring mode commences as soon as
the switch-on procedure is completed.
8.3
Configuring the device
IO-Link functions and device-specific parameters are configured via the device' s IO-Link
communication. Special configuration kits are available, e.g. the FieldPort SFP20. Every IO-
Link device can be configured with it.
IO-Link devices are typically configured via the automation system (e.g. Siemens TIA
Portal + Port Configuration Tool). The device supports IO-Link Data Storage, which enables
easy device replacement.
8.3.1
Switching signal channels and switch output
IO-Link switching signal channels (SSC)
SSCs are specified by the IO-Link Smart Sensor Profile. The device has two independent
SSCs (SSC. 1 and SSC. 2). Based on the measured process temperature, each of the two
channels issues a binary switching signal (OFF or ON) which is transferred to the IO-Link
process data as Switching signal channel 1 and Switching signal channel 2. Both
channels can be configured with the parameters: SP1/SP2, Logic, Mode and Hysteresis;
see section on System Integration. In addition, the output values can be set to a fixed value
using the Simulation switch output .1/.2 parameter (' H igh' becomes ON and ' l ow' becomes
OFF).
In addition to manual configuration for switch points SP1/SP2, a teach mechanism is also
available in the Teach menu. This mechanism writes the current process value to the
selected SSC via a system command.
