Siemens 620 Risk of damage to the Simatic Box PC, Connection Using the PROFIBUS/MPI Interface

Setting Up and Operating the SIMATIC Box PC 620

3.7Connecting the SIMATIC Box PC 620 to a SIMATIC S7 Network (PROFIBUS/MPI)

Connecting an S7 Programmable Controller via PROFIBUS/MPI Interface

You can connect the SIMATIC Box PC 620 to a SIMATIC S7 automation system or to a PROFIBUS network via the potentially isolated*) PROFIBUS/MPI port**). The MPI cable (5m) for connection to SIMATIC S7 CPUs (order no.:

6ES7901-0BF00-0AA0) is supplied with the SIMATIC Box PC 620. Only transfer rates of up to 187.5 kBit/s are possible with this cable connection. The 12 Mbit/s PROFIBUS connecting cable is required for baud rates from

1.5 Mbit/s ( order no. 6ES7901-4BD00-0XA0).

Figure 3-14 Connection Using the PROFIBUS/MPI Interface

Proceed as follows when connecting to a SIMATIC S7 programmable logic control- ler:

1.Disconnect the PC from the power supply.

2.Connect the cable to the PROFIBUS/MPI interface.

!	Caution
	Risk of damage to the SIMATIC Box PC 620!

Before plugging in the cables, the static charge on your body, the unit, and the cables must be equalized. You can do this by briefly touching the metal mounting plate for the interfaces on the left-hand side panel.

* Electrical isolation in the saftey extra-low voltage circuit (SELV circuit). ** Optional product feature
