The conversion of the different byte order between the PC and the PLC is
performed by the OPC server.
Address:
Byte-offset of the variable in the PLC. With strings additionally there has to be
given the length , separated by a point, e.g. <Byte-offset>.<stringlength>.
Example:
The integer value of variable VW100 in the S7-200 with the station name „S1“ e.g.
is addressed as:
MSC:[S1]DB1,INT100
The string with the length 12 at address 1500 of the S7-200 with the station name
„S1“ are addressed e.g. as:
MSC:[S1]DB1,STRING1500.12
Count:
(optional)
Number of array elements that have to be accessed starting with the offset given in
address. If no number is determined, a single variable will be accessed.
A data block in the remote station is always mapped to DB1.
