Control Codes for LCD display

[mauricetclarke]

Hi

Just wondering if anybody knows the control code for resetting the LCD display (not just blanking it), in case of corruption due to noise??

Tried the full manual from the website, but doesn't make much sense.  Doh!  

Thanks

If the LCD display controller is still working then sending it a SETLCD 0,0,CHR$(1) would clear the screen.

If you reset the PLC by executing a "RESET" command or [MaRST] ladder function or by clicking on the RESET button on the online monitoring it will also issue command to reset the LCD display.

But if the LCD controller hang (due to noise coupling on the LCD cable) then there is not much you can do except to power on reset the PLC which will also power on reset the LCD display.
