  • Page 5: Cp 342-5/342-5 Fo Communications Processor

    CP 342-5/342-5 FO Communications Processor Application The CP 342-5/342-5 FO communications processor is intended for operation in a programmable controller of the SIMATIC S7-300 series. It allows the S7-300 to be connected to a PROFIBUS fieldbus system. Design CP 342-5 CP 342-5 FO (9-pin sub-D female (Duplex sockets for optical...
  • Page 6: Characteristics

    Characteristics Services The current version of the CP 342-5/342-5 FO supports the following communication services: S PROFIBUS-DP – as DP master class 1 and class 2 (PROFIBUS-DP complying with EN 50170, DP Master) – as DP slave (PROFIBUS DP complying with EN 50170, DP Slave) Note Note however, that the CP 342-5/342-5 FO can only be operated as DP master or DP slave but not both.
  • Page 7 Module Replacement without PG The CP supports the option of storing the CP configuration data on the CPU. If you use this option, you can replace a module without having to download the configuration data from the programming device. The configuration data are then stored in the load memory of the CPU. The non-volatile storage of the configuration data on the CPU is guaranteed by battery backup or by using an EPROM module card.

    1.2.5 Basic Data for S7 Communication The following characteristic data are important for operating S7 connections: Table 1-8 Feature Explanation / Values Number of S7 connections that can be operated 16 maximum 1) The actual number of S7 connections that can be operated depends on the CPU type you are using. There are further restrictions if you operate in mixed mode.
  • Page 13 Number of Connections in Mixed Mode If you use a connection configuration involving the maximum number of FDL connections (16) and the use of DP at the same time, the maximum number of S7 connections reduces from 16 to 12. Manual CP 342–5 / CP 342–5 FO C79000–G8976–C146/01...
