Hi Gak,

There are couple of ways to communicate with ADAM 4024:

1. ADAM 4024 provides .NET class library in http://www.advantech.com.gr/Support/sr_detail-5032.asp.htm. You can install it and call .NET class library via LabVIEW. You can check http://zone.ni.com/reference/en-XX/help/371361D-01/lvconcepts/using__net_with_labview/ on how to call .NET in LabVIEW.

2. As discussed in http://www.advantech.com.gr/support/sr_detail-5035.asp.htm, ADAM-4000 series can communicate via ADAM OPC server. Therefore, you can use LabVIEW DSC module, http://sine.ni.com/nips/cds/view/p/lang/en/nid/1010, to communicate with ADAM-OPC Server to show data in LabVIEW.

3. If ADAM-4024 can communicate with Modbus like you mention, you can use Modbus LabVIEW Library from http://sine.ni.com/devzone/cda/epd/p/id/4756 to communicate with Modbus device. However, you need to check with Advantech which address to acquire data.

HI Gak

Have gone through the data sheet of the adam daq 4024. if u have gone through the data sheet there u will find the column called type code. this type code is nothing but it will specify the particular channel and u can write the range code to that address. for reference u can see the pic below in the 1st write block u should specify the type code and in 2nd write block u need to specify the channel register address. in the 2nd write block u need to give the values that is No. of holding register values.

Thank you and regards
