Basic Concept

Siemens Protocal is derived by Profibus and Profinet.

Address Mapping

Modbus.Net.Siemens has two types of AddressMapping -- Modbus.Net way or Siemens way.

But Modbus.Net already decleared the type in AddressUnit, so all of the formatting ways will ignore the address type.

The following table shows the differences between them.

Standard Siemens Address Modbus.Net Address Format Siemens Address Format
I0.0 I 0.0 I0.0
IB0 I 0 I0
V10.5 V 10.5 V10.5
VB19 V 19 V19
DB1.DBD22 DB1 22 DB1.DB22
DB2.DB35.1 DB2 35.1 DB2.DB35.1
