Technical Specifications & Selection Guide

To facilitate engineering design and system configuration, we provide standardized technical parameters. Custom configurations are available to match specific project requirements.

Selection Recommendations: When specifying this CPU, consider total I/O point count (integrated + expansion modules), required Profibus network topology, program complexity, scan time requirements, and environmental conditions. For applications requiring safety functions, consider integrating F-modules with appropriate safety CPUs. Our application engineers can review your control narrative, I/O lists, and network architecture to recommend optimal configurations.

Extended Capabilities & System Integration

• Modular Expansion: Add up to 32 signal modules, communication processors (CP 343-1 for Ethernet, CP 342-5 for Profibus), and function modules (FM 350 counters, FM 355 controllers) to scale system capabilities.

Frequently Asked Questions (FAQ)

Q: How do I integrate the CPU 313C-2 DP with existing Profibus DP networks?
A: The CPU supports both DP master and DP slave modes. Configure the Profibus address, baud rate, and GSD files in STEP 7 hardware configuration. Ensure proper bus termination (active terminators at both network ends) and verify cable specifications (Type A for up to 12 Mbps). Our engineers can provide network topology review and commissioning support.

Q: What is the maximum number of I/O points this CPU can handle?
A: The integrated I/O provides 24 DI + 16 DO. With expansion modules on the S7-300 rack, the CPU 313C-2 DP supports up to 1024 digital I/O points and 256 analog I/O channels, depending on module selection and addressing configuration.

Q: Can this CPU communicate with non-Siemens devices via Profibus DP?
A: Yes, Profibus DP is an open standard (IEC 61158). The CPU 313C-2 DP can communicate with any Profibus-compliant device (drives, I/O blocks, sensors) from manufacturers like ABB, Schneider Electric, Phoenix Contact, and others, provided correct GSD files are imported into STEP 7.

Q: What programming software is required, and is it compatible with TIA Portal?
A: The CPU 313C-2 DP is natively programmed using STEP 7 V5.x (Classic). For TIA Portal compatibility, use TIA Portal V13 or later with S7-300/400 support packages. Migration tools are available to convert existing STEP 7 V5.x projects to TIA Portal format.

Q: What are the environmental and installation requirements?
A: Operating temperature range: -25°C to +60°C; storage: -40°C to +70°C. Install in a clean, dry control cabinet with adequate ventilation. IP20 protection rating requires enclosure mounting. For harsh environments (high humidity, corrosive gases), specify conformal-coated versions or use sealed enclosures with climate control.

Q: Does this CPU support remote monitoring and diagnostics?
A: Yes, via Profibus DP to SCADA systems, or by adding a CP 343-1 Ethernet module for TCP/IP connectivity. Remote access can be established using Siemens TeleService, VPN routers, or cloud-based IoT gateways for real-time monitoring, alarm notification, and remote program modifications.
