Logo VM parameter mapping
#3

There seems to be a "bug" in the Siemens Logo8.3.

When a parameter has the address Word :0 the modbus address is 0
When a parameter has the address Word :2 the modbus address is 1
When a parameter has the address Word :4 the modbus address is 2

So you always have to divide the address by 2.

The same happens with a Dword.

I figured this out by checking the values with qModMaster

Hi, I've found out that this is right, always divide by 2 the VM address. I'm now struggling with another issue; I have a timer B003 VM address is 48, values are hh:mm I can change the mm value by writing the address 24 but I have no clue on how to change the hh value.
Basically I can change the minute, in fact if I write 63 in minutes from Virtuino  I have 01:03 on the LOGO that is correct but I need to set the time in the format hh:mm, any suggestions?

I hope I have been clear
