PG routing from a SINAUT ST7cc control center with SIMATIC STEP 7
In this case, PG routing does not extend from a PG in the master station but from a central
SINAUT ST7cc control system connected to the MPI bus of the master TIM. The routing path
shown here is basically the same as described in the basic configuration with a centrally
configured PG.
A SINAUT system configuration equipped with SINAUT ST7cc as the central control system
already has the full range of functions of PG routing if SIMATIC STEP 7 is also installed
alongside the SINAUT ST7cc software. PG routing is then activated in any case. This means
that no further preparations are necessary for PG routing to be able to use the parameter
assignment, diagnostics, and service functions for remote subscribers over SINAUT
networks.
For this configuration, PG routing extends from the PC with the STEP 7 software over the
master TIM and a SINAUT network to a SINAUT station where both the station TIM and the
CPU can be accessed.

Indirect PG routing over remote PC / laptop with remote access
The configuration below is initially the same as with the central SINAUT ST7cc control
system. PG routing, in this case, is used with a remote PC connected over the
telephone/ISDN network. With the aid of remote access software, a connection is
established to the PC in the master station so that this can be controlled by the remote PC /
laptop over the telephone/ISDN connection. From there, PG routing extends over the master
TIM and a SINAUT network to a SINAUT station where both the station TIM and the CPU
can be accessed.
Various products, such as Symantec pcAnywhere are available on the market and can be
used as remote access software.
