Terminal point assignment of the RS-485 interfaces
Data is transmitted via the RS-485 interface in half duplex mode. In half duplex mode, sev
-
eral devices can be operated simultaneously via the serial bus.
In PC Worx, the interfaces are operated via function blocks. They can be downloaded as a
StartUpPackage in the product download area on the e-shop.
