6 Modbus.Net.Siemens(E)
Siemens protocol is based on Profibus and Profinet by Siemens, including PPI, MPI and TCP.
Modbus.Net.Siemens has two ways to describe address, Modbus.Net method and Siemens standard method.
But there is already had a property called DataType that shows the data type of an address in AddressUnit, so data type alphabet has been removed from both Modbus.Net method and Siemens standard method.
Following table shows the difference between them.
| Standard Siemens | Modbus.Net Method | Siemens Standard Method |
|---|---|---|
| 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 |
