Hi,

You need to map a funktion block which supports the dataformat DW. Open the LOGO! Soft Comfort help and search for “VM”. In parameter VM-mapping you find any LOGO! function and the used dataformat for each parameter. 

For DW there are only a view functions blocks (Up/Down counter, Astro clock, Stop watch, OHC)

Only this FB's with the right paramter can be used in your way with VM-mapping.

Please note, LOGO! only support signed integer values. This means if you want to handle a DW value LOGO! is very limited.

If you just use LOGO! to forward such a value for example read a DW of the energy meter and forward it to cloud, then just transfere the value into the V-Memory of LOGO! and forward it to cloud. LOGO! doesn't change such values.

Hope this helps
