Overview Manuals Host Fit Review MPI Operating Boundary Migration Decision Product Applications

Features:

  • Legacy MPI access: supports the documented online connection path to SIMATIC S7, M7 and C7 systems.
  • Isolated ISA hardware: combines a short ISA card format with optical isolation for the communication interface.
  • Defined migration boundary: Siemens documented a later PCI-format path, but software and host compatibility still require review.
The exact C79458-L7000-B315 label is the primary receiving reference for this legacy communication board.

The associated Siemens order record defines the card role, host-bus format and intended controller families without turning those facts into a substitute for installation verification.

Maintenance planning should preserve the current driver, cable and engineering-software record before the original board is removed.

Apter Power supports Siemens C79458-L7000-B315 SIMATIC S7 MPI Communication Card identity review, quotation and legacy sourcing after OEM discontinuation.

Important 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.
  • Bus requirement: confirm the maintenance computer has the required ISA expansion slot.
  • Physical comparison: match the edge connector, bracket and complete label before insertion.
  • Stop condition: do not use an unverified bus adapter to force installation in a different host architecture.
  • Supported systems: use the card for the documented online path to S7, M7 or C7.
  • Software record: retain the working STEP 7 and driver versions before service.
  • Cable scope: verify the actual cable supplied rather than assuming the original article bundle is complete.
  • Lifecycle trigger: the associated MPI-card article is no longer in the current Siemens range.
  • PCI alternative: Siemens documented CP 5611-MPI as a later path with software restrictions.
  • Approval boundary: validate the PC slot, operating system and engineering release before migration.
  • Legacy S7 service: provide the documented MPI online connection from a compatible engineering PC.
  • M7 and C7 maintenance: retain access for installed systems that depend on the original MPI-card architecture.
  • Controlled spare strategy: hold an exact, tested card for a verified ISA-based maintenance workstation.
Description
C79458-L7000-B315 is the Siemens hardware code confirmed from the supplied board label for the MPI communication card associated with Siemens order number 6ES7793-2AA01-0AA0. The short ISA format places it in legacy PG/PC hardware rather than modern PCI or USB architectures.

Siemens describes C79458-L7000-B315 through the associated official article as an optically isolated MPI card for online connection to S7, M7 and C7 systems. The official article scope includes a 5 m MPI cable, but buyers should verify the actual offered stock description before assuming that any cable is supplied.

Siemens removed the associated MPI card from its current product range in 1998, and the present product record shows the end of its lifecycle without replacement. Apter Power can assist with identity review and sourcing of C79458-L7000-B315 for documented legacy installations.

Technical notes
Before installing C79458-L7000-B315, confirm that the host computer provides the required short ISA slot and that the installed STEP 7 environment supports the intended MPI connection. Record the existing card, cable and driver arrangement before removal. Stop the replacement if the host interface, software generation or complete hardware identity cannot be reconciled.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can C79458-L7000-B315 be installed in a modern PC without an ISA slot?
No. Siemens identifies the associated hardware as a short ISA card. If the maintenance PC lacks the required slot, stop the exchange and assess a documented migration path instead of using an unverified adapter.
Which Siemens systems can C79458-L7000-B315 connect to for maintenance?
Siemens specifies online connection to SIMATIC S7, M7 and C7 systems. Confirm the installed engineering software, cable arrangement and target controller before scheduling maintenance access.
Should a buyer assume that C79458-L7000-B315 includes the 5 m MPI cable?
No. The associated Siemens article description includes a 5 m MPI cable, but surplus stock may contain only the card. Require the quotation and packing list to state whether the cable is included.
Can C79458-L7000-B315 be replaced directly by the later CP 5611-MPI?
Not without a compatibility review. Siemens presented CP 5611-MPI as the later PCI-format path, while also documenting software-version restrictions. Verify the host slot, operating system and STEP 7 release before approving migration.
What should receiving inspect before accepting C79458-L7000-B315?
Match the complete C79458-L7000-B315 label, Siemens identification, ISA edge connector and bracket condition to the purchase record. Quarantine the card if the identity is incomplete or the connector shows damage that could compromise insertion.
Why does lifecycle status matter when sourcing C79458-L7000-B315?
Siemens removed the associated MPI card from its current range in 1998 and now shows the article at end of lifecycle. Procurement should therefore verify the installed legacy environment and available testing evidence before purchase.
