Entry ID: 109480894,
V1.0,
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 CM PtP RS422/485 communication module to the SIMATIC S7-1500
station.
Physically establish the USS bus connection between the 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 right of it (2).
Program extension in TIA Portal
In the project tree, copy the code blocks ...
Cyclic_interrupt
UssCyclic
The copies are automatically created with index _1:
Cyclic_interrupt_1
UssCyclic_1
The name of the copied blocks can be changed in the block properties.
Open the Main OB (OB1). Now drag the copied block, UssCyclic_1, to a network
and supply it with a new instance data block.
