6GK7342-5DA03-0XE0 Siemens SIMATIC S7-300 CP 342-5 PROFIBUS DP Communication Processor

Product Overview: Siemens 6GK7342-5DA03-0XE0

Parameter Specification
Brand Siemens
Order Number 6GK7342-5DA03-0XE0
Product Name CP 342-5 – Communication Processor PROFIBUS DP
Product Family SIMATIC S7-300 (add-on communication module)

Application & Fault Scenarios

Typical Uses: Adds PROFIBUS DP connectivity to S7-300 CPUs without an integrated DP port — connecting ET 200 remote I/O, SINAMICS/G120 drives, MM440 inverters, weighing/packaging machines and third-party devices via GSD files. Also used for master-to-master DX exchange and replacing failed CP 342-5 cards in brownfield plants.
Common Field Issues:
  • BF (Bus Fault) LED red / SF red → check bus cable continuity, terminating resistors at both ends, station address conflicts and baud-rate mismatch; verify the SUB-D plug is fully seated.
  • Module not recognised / STOP after insertion → ensure firmware/HW revision matches the STEP 7 hardware catalogue; update catalogue or re-download hardware configuration.
  • I/O data inconsistent / placeholders "???" → confirm FC1/FC2 call parameters (LEN, ANY pointer) and consistent data area settings match the slave configuration; check watchdog timeout.
  • Intermittent faults after cabinet work → inspect shield bonding at the connector (screen clamp, not pigtail), earth potential differences between cabinets, and cable routing away from power lines.

FAQ

Q1: What is 6GK7342-5DA03-0XE0?
A: It is the Siemens CP 342-5 PROFIBUS DP communication processor for SIMATIC S7-300, configurable as DP master or slave, 9.6 kbit/s–12 Mbit/s, with one SUB-D 9-pin RS-485 port and support for direct data exchange (DX).
Q2: Can it replace my failed CP 342-5?
A: Yes — the base order number matches. Check the hardware/firmware revision and re-download the hardware configuration after fitting; you may also need to update the STEP 7 hardware catalogue.
Q3: Does it work with S7-1200/1500 or TIA Portal?
A: No. It is an S7-300 module designed for STEP 7 V5.x (SIMATIC Manager). For S7-1500 use CM/CP 1542-5 instead.
