        • PRODUCT OVERVIEW

          What is this product?

          The 6GK7342-5DA02-0XE0 CP 342-5 adds a PROFIBUS communication interface to a compatible SIMATIC S7-300 station. Its nine-pin RS-485 connection links the controller to an engineered fieldbus network, with the DP role selected as either master or slave. The documented communication services also include S7 functions and FDL exchange, subject to the configured project and resource limits. As a DP master, the archived DA02 specification supports up to 124 slaves and separate input and output areas of 2160 bytes. These system limits do not remove the per-slave and CPU-program constraints. Replacement planning should retain the exact order suffix, hardware revision, firmware, bus address and engineering configuration. The later DA03 model has its own specifications and replacement restrictions, so it must not be treated as identical. This product is a PROFIBUS processor, not an Ethernet interface or an optical CP 342-5 FO.

          Source boundary

          Technical figures are taken from Siemens C79000-G8978-C146, edition 01, June 2000, explicitly identifying DA02. The linked three-page excerpt is in Spanish and is labeled as an excerpt, not a complete installation manual.

      Information

      Overview Manuals DP Master/Slave Setup PROFIBUS Wiring DA02 Revision Check

      Features:

      • PROFIBUS integration: Provides an RS-485 fieldbus connection for compatible SIMATIC S7-300 stations.
      • Configurable DP role: Supports DP master or DP slave operation according to the engineered project.
      • Documented DA02 capacity: Up to 124 slaves and 2160-byte input/output master areas, subject to per-device and project limits.
      The CP relieves the S7-300 station of specific communication tasks while the application remains dependent on its CPU, program blocks and network configuration. Engineering should account for the selected bus rate, segment design, termination and data-area allocation.

      Check the existing DA02 project before ordering a spare or considering a newer CP. Preserve the hardware and firmware records, confirm the required communication services and review the manufacturer’s legacy-device security guidance before commissioning.

      Siemens SiePortal lists 6GK7342-5DA02-0XE0 as discontinued and identifies DA03 as a successor. Moore Automated can check installed-base supply; any successor proposal still requires the OEM compatibility and project review.
      Siemens 6GK7342-5DA02-0XE0 CP 342-5 — archived OEM excerpt, Spanish, June 2000 (pages 1, 8 and 23), LinkImportant Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

      Master or slave configuration

      The CP can operate as a DP master or a DP slave. These roles are mutually exclusive. Other documented communication services and resource limits must be evaluated within the configured S7-300 project.

      RS-485 PROFIBUS

      A nine-pin female D-sub connects the electrical PROFIBUS interface. This DA02 execution is not the optical CP 342-5 FO and is not an Ethernet CP. Match bus rate, termination, shielding and segment layout to the installation.

      DA02 is not DA03

      The archived specification used here identifies DA02 hardware from version 1 and firmware V4.0.0. Later DA03 documentation includes differences; use the applicable OEM replacement notes and the installed project when considering migration.

      Technical notes

      Confirm the DA02 hardware and firmware revision, S7-300 CPU, STEP 7 project and configured DP role before replacement. DP master and DP slave operation are alternatives, not simultaneous roles. This RS-485 CP must not be confused with the CP 342-5 FO optical version or CP 343-1 Ethernet hardware. The linked archived June 2000 document explicitly covers DA02 from hardware version 1 / firmware V4.0.0; it does not establish the revision of the offered unit. Siemens security advisory SSA-763427 lists DA02 among affected legacy devices with no fix planned; apply the manufacturer’s network-protection recommendations and project-specific security review.

      Project Matching Checklist

      Provide the complete 6GK7342-5DA02-0XE0 marking, hardware/firmware revision, S7-300 CPU and STEP 7 version. Identify the configured DP role and any FDL or S7 services so the offered processor can be assessed against the actual project.

      Replacement Acceptance Scope

      Confirm condition, quantity, diagnostic evidence and included connectors in writing. Record the network address and configuration backup before replacement. A DA03 proposal requires the OEM replacement-compatibility review, not an assumption based only on the CP 342-5 family name.

      Customs & shipping dimensions / weight

      • Packed shipping dimensions
        Confirmed after final packing
        Siemens DA02 manual C79000-G8978-C146/01 lists device dimensions of 40 x 125 x 120 mm. These are not packed shipping dimensions; the final package is measured after packing.
      • Packed shipping weight
        Confirmed after final packing
        The archived June 2000 Siemens manual gives approximately 300 g device weight; the current exact-order SiePortal record gives 0.334 kg net. These are product references, not packed gross weight; the actual shipment is weighed after packing.
      • HS / customs code
        Confirmed before dispatch
        The customs declarant confirms classification for the supplied goods and destination.
      • Country of origin
        Verified on the supplied unit
        The nameplate and applicable origin documents are checked for the actual unit; the brand alone is not proof of origin.
      • Ships from
        Xiamen, Fujian, China
        The dispatch location is confirmed in the written quotation.

      PRODUCT & ORDER FAQS

      Questions buyers ask about 6GK7342-5DA02-0XE0

      • Is 6GK7342-5DA02-0XE0 an Ethernet processor?

        No. It is a CP 342-5 PROFIBUS processor with a nine-pin RS-485 interface. CP 343-1 Ethernet models and the CP 342-5 FO optical version are different hardware.

      • Can it be a DP master and DP slave simultaneously?

        No. The DP master and DP slave roles are alternatives selected in the configuration. Review other communication services separately against the project and resource limits.

      • How many DP slaves are documented for DA02?

        The archived exact-version manual lists up to 124 slaves in DP-master operation, with 2160-byte input and output areas. Per-slave limits and CPU/application constraints still apply.

      • Why are DA03 specifications not copied to this page?

        DA03 is a later execution with documented differences and replacement conditions. The DA02 data here is anchored to the Siemens manual that explicitly identifies 6GK7342-5DA02-0XE0.

      • Which installation and security checks matter?

        Match the CPU, STEP 7 project, firmware, bus rate, address, shielding and termination. Review Siemens SSA-763427 and the OEM network-protection recommendations for the affected legacy DA02 device before commissioning.

      • How do I confirm availability and supplied revision?

        Request a quotation against the complete order number and required revision. Current quantity, physical condition, included connectors and acceptance-test evidence are confirmed for the offered unit.

      • What warranty applies to the order?

        Moore Automated offers a one-year warranty subject to the written sales terms. Confirm supplied condition, coverage and the claims procedure before purchase.

      • Are the published dimensions the final shipping size?

        No. The 40 x 125 x 120 mm and approximate 300 g values describe the device in the archived OEM manual. Final package dimensions, gross weight and dispatch timing are confirmed for the order.
