Notice
When a new OPC item at the SINAUT MICRO SC OPC server is created, at the
first time 64 bytes will be readout of the CPUs memory to optimize GPRS data
volume. If the memory address is at the memory edge of the CPU, error messages
may occur at the SINAUT MICRO SC. These error messages can be ignored.
Stationname:
The station’s name to access. This name is part of the station’s configuration.

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
