More Information

Overview Manuals PROFIBUS Roles Service Paths Power Paths Engineering Limits

Features:

  • The CP 342-5 connects an S7-300 station to one electrical PROFIBUS DP segment.
  • The processor supports DP, S7, PG/OP, open and S5-compatible communication services.
  • A single-width rack format combines backplane access with a separate 24 V DC power connection.
The processor places PROFIBUS communication work outside the CPU while exchanging configured data through the S7-300 backplane.

DP master and DP device modes determine whether the module coordinates remote stations or exposes transfer areas to another master.

Connection resources are shared across DP, S7 and open communication, so the selected network role defines the available multi-protocol capacity.

The Siemens 6GK7342-5DA03-0XE0 CP 342-5 Communication Processor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Master and device operation

  • DP master: The processor coordinates configured field devices and maps their data into the S7 station.
  • DP device: The processor can instead present defined input and output areas to another DP master.
  • Bus connection: A 9-pin Sub-D RS485 socket provides the electrical PROFIBUS interface.
  • Baud range: The interface supports the documented PROFIBUS rates through 12 Mbit/s.

Communication resource sharing

  • S7 services: S7 communication exchanges controller data through configured connections.
  • PG/OP access: Programming devices and operator panels use the supported service path.
  • Open communication: SEND/RECEIVE jobs use dedicated connection and payload limits.
  • Mixed operation: Active-connection capacity changes when DP and other protocols operate together.

Rack and external supplies

  • Backplane path: The S7-300 rack supplies 5 V DC to the module electronics.
  • External path: A four-pole terminal block accepts the 24 V DC field supply.
  • Dual-source structure: Both sources are part of the operating power arrangement.
  • Rack position: The compact processor occupies one S7-300 module width.

Configuration boundaries

  • Engineering tools: The processor is configured with the supported STEP 7 or TIA Portal release.
  • CPU allocation: Up to four CP 342-5 units can be assigned to one CPU.
  • DP capacity: A master configuration can address up to 124 DP devices.
  • Payload mapping: Per-device and total address limits govern how DP data is allocated.
Description
Siemens 6GK7342-5DA03-0XE0 is a SIMATIC NET CP 342-5 communication processor for linking an S7-300 station with a PROFIBUS DP network. It transfers process and diagnostic data between the controller backplane and devices connected to its RS485 bus port.

At the fieldbus side, 6GK7342-5DA03-0XE0 uses a 9-pin Sub-D socket and can organize the configured address areas as a DP master or present its own transfer areas as a DP device. PG/OP and S7 communication share the processor's supported connection resources.

Power for 6GK7342-5DA03-0XE0 enters through two paths: 5 V DC comes from the S7-300 backplane and an external terminal accepts 24 V DC. The processor combines these sources with a single-width module format in the controller rack.

Engineering 6GK7342-5DA03-0XE0 assigns the DP role, connected devices and communication jobs in STEP 7 or the supported TIA Portal version. The configured connection limits determine how open communication, S7 services and DP traffic share the processor.

Technical notes
Siemens 6GK7342-5DA03-0XE0 uses one 9-pin RS485 PROFIBUS socket and receives power from both the S7-300 backplane and an external 24 V DC supply.
