m.UInt8Value(2) = 0 // some data...
m.UInt8Value(3) = 0
m.UInt8Value(4) = 0
m.UInt8Value(5) = &h21
m.UInt8Value(6) = 0 // checksum comes here
m.UInt8Value(7) = 0
m.UInt8Value(8) = 4 // end of package

dim Data as string = m.StringValue(0,6)
dim CheckSum as Int16 = ModBusCalculateRTUMessageCRCMBS(data)

m.UInt16Value(6) = checksum
