## What is S7Scout?

S7Scout is the little pocket knife for the Siemens S7 specialist.

With this tool you are able to connect to a Simatic S7-300 or S7-400 PLC, and read or write data to the PLC. The communication is done over TCPIP using the RFC1006 protocol.

All you need is the hostname or ip-address of the PLC and its TSAP.

Get data access to memory, data blocks, inputs and outputs. The variable table has to be filled out with the common S7 conventions like MX0.0, MB0, DB10.DBW5 and so on. For any variable you can change its display format like 
- binary
- bool
- decimal
- hexadecimal
- real
- ASCII
- time
- SIMATIC time (S5Time)
- daytime
- counter

The connection will work via WLAN or mobile connection!
