Title: F 2424 and MD-HMI
Post by: cch1955 on March 25, 2010, 09:28:06 AM

I am using this F2424 for the first time. The display is working fine but I am not seeing the keypad inputs when pressed using online monitoring. I am using the same key routine from your samples that I have used with the T100MD2424+.

I see no mention to the base address for the F2424 when using the MD-HMI Am I correct that it is the same as the T100MD2424+ ?

The zero key starts at input 25 and input 40 is the last input for the F4 key.

My program works fine in simulation, just not with the hardware.

Possibly I have a hardware problem with the keypad that does not effect the LCD?

Thanks

Did you plug in the 10 way connector into the Expansion socket (on the right edge of the PLC). It is a common tendency for F-series user to plug into the socket next to the LCD display. I know it may sound logical but that socket next to the LCD socket is reserved for future implementation of CANbus and is not currently used.

A simple solution. Another guy plugged in the cables and I did not notice the location.

I moved the cable and all works well.

Thanks for the prompt reply.
