6 Starting
►
NOTICE
Starting
Before switching on ensure that the unit was stored at the ambient temperature (-20… + 50 °С)
at least 30 minutes.
– After switching on the device starts booting. The process takes 25 seconds.
– After the boot process has been completed the message TAP 3 TIMES TO SERVICE
MENU appears for 3 seconds.
– If you touch the display 3 times within 3 seconds, the service menu will appear.
Fig. 6.1 Start screen
– Then the most important parameters can be set and the basic functions of the device
can be used. For the detailed description of the service menu see sec. 6.
– If you don’t touch the display within 3 seconds or you left the service menu, and there
is a user program on the PLC, it will be immediately executed.
– If no user program is on the PLC, the display looks after booting as follows:
Fig. 6.2 Display without user program
– The PLC must be connected via Ethernet cable to the PC with CODESYS to load a
user program. For details see Appendix C.
– Once the user program has been loaded to the PLC, it will be executed.
– For the programming instructions refer to the CODESYS documentation.
