The CP 443-5 Extended operates as DP-V1 master. It processes data transfer autonomously and allows slaves to be connected, such as CP 342-5 as DP slave, DP slaves of the ET 200 distributed I/O system, etc. This means that the CP 443-5 Extended is able to connect the S7-400 station to PROFIBUS DP and is the ideal expansion to the integral DP master interfaces of the S7-400 CPUs for establishing additional PROFIBUS DP lines.
The CP 443-5 Extended can also be used in the SIMATIC S7 H system as a redundant DP master.
The CP 443-5 Extended is a DP-V1 master, i.e. it also supports the acyclic standard services incl. interrupt handling.
The CP 443-5 Extended also supports the SYNC and FREEZE functions, constant bus cycle time, direct slave-to-slave traffic, data set routing and changes to the configuration of the assigned distributed I/O during normal operation.
During normal operation, it is also possible to activate or deactivate DP slaves. This supports the step-by-step start-up of subprocesses, for example.
A diagnostic repeater allows the line to be diagnosed during operation, enabling line faults to be detected at an early stage. The CP 443-5 Extended supports operation with diagnostic repeater (including activation of topology identification in the diagnostic repeater).
The distributed I/Os are handled like central I/Os from the user's point of view. This means that there are no differences between the CP 443-5 Extended and the integral DP master interface of the S7-400 CPU with regard to configuration and parameterization. Depending on the scale of the system, the CP 443-5 Extended has extremely short response times.
