Product Description

The 4PP045.IF24-1 is a 3-in-1 interface module designed by B&R Automation for power panels under the PP45 product series. It has three communication interfaces that extend the available communication ports of compatible PP45 power panels. The 4PP045.IF24-1 offers one Profibus DP slave interface, RS232, and RS485/RS422. Overall, this interface module provides two 9-pin DSUB connectors. The first 9-pin DSUB connector provides an interface for both the RS232 and RS485/RS422 communication protocols. The second 9-pin DSUB connector is for the Profibus DP slave. In terms of transfer rate, both IF1 (RS232) and IF2 (RS485/RS422) may reach a maximum transfer rate of 115.2 kbit/s, while IF3 (Profibus DP slave) may reach a higher maximum transfer rate of 12 Mbit/s.

Like other interface modules by B&R, the 4PP045.IF24-1 offers status indicators during data transfer. For this module, each interface has an assigned status indicator. Interfaces one and two share the same 9-pin DSUB connector, and they are not electrically isolated. The second DSUB connector is for the Profibus DP slave, and it is electrically isolated from other interfaces. Aside from the connectors, the 4PP045.IF24-1 also features two hex switches that set the node number for the Profibus DP slave interface. It also has two terminating switches at its back for toggling IF2 (RS485) and IF3 (CAN bus).

Although both RS232 and RS485/RS422 share the same DSUB connector, both communication interfaces can be used simultaneously when correctly wired. B&R Automation's manual for IF24 details the pin assignments for both interfaces, including the one implemented for the third interface. Among the three available communication interfaces, the third supports longer transfer distances and faster transfer rates. B&R Automation's manual elaborates on other technical details and information relevant to the 4PP045.IF24-1.
