Expansion to multiple drives
The application example operates one SINAMICS V20. However, up to 16 drives
can be operated via one port. To increase the number of drives, proceed as
follows:

Expansion to multiple ports
You can provide the CPU with a maximum of three communication modules and
one communication board. Up to 16 drives are possible on each module/board. In
the section below, you will learn how to expand the application by a port.

SINAMICS V20 at S7-1200/1500 via USS
Entry ID: 109480894, V1.0,
Add the number of desired drives to your configuration as shown in Figure 5-2.
Follow no. 1 to 10 of Table 4-1 to parameterize the added inverters using the
built-in BOP. From "2" onward, the drive addresses have to be assigned
continuously.
Change the program so that the USS_DRV block is called for each drive. In this
process, the appropriate address of the drive must be entered in the DRIVE input
variable.
Installing and wiring new hardware
As shown in Figure 5-2, add the drives to your configuration that are to
communicate with the controller via the new, additional port.
Add a new CM1241 (RS485) communication module to the SIMATIC S7-1200
station or insert a CB1241 (RS485) communication board into the CPU.
Physically establish the USS bus connection between the new drives and the
new port.
Parameterizing new drives using the BOP
Follow no. 1 to 10 of Table 4-1 to parameterize the added inverters using the
built-in BOP. From "1" onward, the drive addresses have to be assigned
continuously.
Device configuration in TIA Portal
In the device configuration, copy the existing communication module (1) and
paste it directly to the left of it into slot 102 (2).
