Features:
- A 16-bit ISA interface connects the CP 1413 hardware to an AT-compatible host.
- One ITP Ethernet port links the host application to the SINEC H1 network.
- Jumper-selected I/O addresses, IRQ, and dual-port RAM must be reserved before driver startup.
Siemens C79458-L2343-A2 provides the CP 1413 hardware path between a host PC and SINEC H1 communication.
Resource settings on C79458-L2343-A2 keep its ISA I/O space and interrupt separate from other host adapters.
The SIMATIC NET configuration for C79458-L2343-A2 binds the hardware resources to the required application access point.
Verify the complete Siemens C79458-L2343-A2 SIMATIC NET CP 1413 SINEC H1 Communication Processor article number and interface configuration before matching the installed unit.

Host Address and Interrupt Assignment
- I/O range: One of three eight-address ISA ranges is selected before installation.
- Interrupt: IRQ 5, 10, 12, or 15 must remain free for the processor.
- Conflict check: SCSI, sound, network, and other cards are checked for overlapping resources.
- Restart: Changed resource values take effect only after the documented host restart.
Shared Host Memory Window
- RAM role: Dual-port RAM exchanges commands and data between the host driver and communication processor.
- Memory size: The configuration selects a 64 KB or 256 KB window.
- Address boundary: The chosen memory area must not be used by another host component.
- BIOS limits: Older hosts can restrict which ISA memory ranges are accessible above 16 MB system memory.
SINEC H1 Communication Chain
- ITP port: The network connector carries the CP 1413 industrial Ethernet path.
- Host application: SIMATIC NET software routes application requests through the configured processor.
- Access point: The PG/PC interface assignment links the application name to the CP 1413 parameter set.
- Address identity: The configured Ethernet address must agree with the project and network database.
Driver and Hardware Setup Order
- Jumper setting: X3 is set to the selected I/O range before the card is installed.
- Driver resources: The configuration tool records I/O range, IRQ, and dual-port RAM values.
- Hardware install: Power is removed before inserting the ISA card in the host slot.
- Diagnostic review: Windows event messages and PG/PC interface status identify startup resource conflicts.
