VIPA CPU 314SB 314-2AG13 – High-Performance Standalone PLC CPU | SPEED7 Platform
Engineering Background
The VIPA CPU 314SB (314-2AG13) is a standalone programmable logic controller CPU built on VIPA’s proprietary SPEED7 architecture, delivering processing performance that significantly exceeds standard Siemens S7-300 CPUs of the same class. Designed for demanding industrial automation environments, this CPU combines high-speed instruction execution with broad compatibility with the Siemens STEP 7 / TIA Portal programming ecosystem, making it a preferred choice for system integrators and OEM machine builders seeking performance upgrades without full platform migration.
Product Positioning
The 314SB is positioned as a drop-in performance replacement for Siemens S7-314 class CPUs in existing S7-300 rack installations, while also serving as a standalone controller in new builds. Its onboard I/O capability, extended memory, and SPEED7 execution engine make it suitable for mid-to-large scale discrete and process control applications across manufacturing, energy, and infrastructure sectors.

- Siemens S7-300 Compatibility: Accepts existing STEP 7 programs with minimal or no modification — zero retraining cost
- Onboard I/O: Integrated 16 DI / 16 DO eliminates the need for a separate SM module in small-to-mid configurations
- Extended Memory: 512 KB work memory vs. 128 KB on standard CPU 314 — supports larger, more complex programs
- Standalone Operation: Can operate without a rack in standalone mode, reducing BOM cost for compact machine builds
- Long-term Availability: VIPA maintains production continuity for industrial lifecycle requirements (10+ year availability)
System Architecture & Signal Flow
The CPU 314SB mounts in slot 2 of a standard S7-300 UR rack. The SPEED7 core executes the user program cyclically, scanning onboard DI inputs, updating the process image, executing logic blocks (OB/FB/FC/DB), and writing outputs to onboard DO and any downstream SM expansion modules via the S7-300 backplane bus. MPI/DP interface supports programming, HMI communication (e.g., Siemens TP/OP panels), and peer-to-peer PLC networking. An MMC card slot provides non-volatile program storage and load memory extension.
Signal flow: Field sensors → DI (onboard/SM) → Process Image Input → CPU SPEED7 Core (OB1 cycle) → Process Image Output → DO (onboard/SM) → Field actuators

Technical FAQ
Q: Is the CPU 314SB (314-2AG13) a direct replacement for Siemens 6ES7 314-2AG23-0AB0?
A: Yes. The 314SB is designed as a functional replacement for the Siemens CPU 314-2 DP class. Existing STEP 7 programs can be downloaded directly in most cases. Verify hardware configuration settings in HW Config before going live.
Q: Can I use TIA Portal to program this CPU?
A: VIPA recommends SPEED7 Studio (free download) or Siemens STEP 7 v5.x. TIA Portal support is available via VIPA’s TIA compatibility layer — consult the VIPA manual for the specific firmware version.
Q: Does the onboard I/O require a separate power supply?
A: The CPU logic is powered via the S7-300 backplane (PS 307). The onboard DO outputs require a separate DC 24 V load supply connected to the front connector.
Q: What is the maximum number of expansion modules?
A: Up to 8 SM/FM/CP modules per rack, with up to 3 expansion racks (ER) via IM 360/361 interface modules — identical to standard S7-300 architecture.
Q: Is a warranty provided?
A: Konmask.com provides a 90-day functional warranty on all modules. Extended warranty and exchange programs available for volume B2B orders.
