Reading 2 consecutive DM with Omron Plc with 1Tag

[GVIntegrator]

SW:Bridgeview 2.1, IA Servers 4.0
HW: RS422 and OMRON PLC
I've configured an Item to read two consecutive DMs (with Serv. Explorer), but I get an error trying to define the corrisponding tag (I've used a Bit Array tag with Tag Configuration utility).
P.S.: if I set the itemcount to 1,the tag is OK. Setting the itemcount to 2 I get an invalid type error.

How should I read 2 consecutive DMs?

You can not read two consecutive DMs using one tag in Labview DSC. You will need to read each of them individually and then "AND" them together using labview code.
