HMI value to 16bit DO

Hi everyone

I am trying to get values that are set on hmi to digital out as 16 bit.  

there is no problem to do it with a value on hmi up to 255 and move this to QB0, but that only gives me 8 bit, i have values up to 42000 so i need 16bit.

how can i move "hmi_value" to use QB0 and QB1 so that i have 16bit out ? 

Using Simatic manager  step 7, plc S7-400

Hi Sonderso,

Suggestion, try to use BYTE elements to the outputs direclty.  

Hello Sandersa,

use at the HMI a variable as a INT.

At the PLC move the INT to a WORD (e.g. FW100), (it's "not" necessary)

Then move the Bytes to the output.
Important is that you must change the Bytes.

e.g.
HMI value to FW100
FB101 -> QB 0
FB100 -> QB 1

 How about QW0?
