IO-Link interface description
39
teach values are only accepted after the second teach-in. With the teach-in of the single point mode,
the switching point results from the mean value of the two teaching points: SP = 1/2 (TP1 + TP2). The
keys [A], [B] and [Edit] are locked during the teach-in. The display flashes alternately ‘t-IN’ and ‘IOL’.
1. Set the first desired flow rate.
2. Send the teach-in command 0x4B.
3. Set the second desired flow rate.
4. Send the teach-in command 0x4B.
The teach process is aborted with the command 0x4C.
Recommendation: After teaching, read out the parameter set and check whether the settings match
the application.

Block parameterisation
Block parameterisation is used to prevent individual parameter values from being incompatible with
the values stored in the device. All parameters transmitted as a block will be simultaneously accepted
and activated.
