    Dimetix laser distance sensor and the safe values of the device are activated. The “RUN/REM/PROG" switch must be set to RUN to set the RUN flag in the Run/Idle header of the process data frames. Otherwise the Dimetix laser distance sensor does not take over the output data and the safe values of the device are activated.

    LASER DISTANCE SENSORS 10 PLC application 10.4.4 Distance unit – Read The routines in figure 22 show the acyclic read service (MSG) to read the distance unit of the module. This read service can be triggered with the associated controller tag “Distance_Unit_Read_Ctrl”. So that this acyclic message instruction is only done once, the OSR (One Shot Rising) instruction block is used in addition.

There will be a warning to indicate that the access to the device will be lost. Remark: After the change of the IP parameter, the access to the device will then be lost because of different IP parameter in the PLC project and the device.
