Memory Rule: Divide ControlLogix memory by 2 for Siemens program memory. Safety PLCs require a Safety Partner.
Pro Tip: For high-I/O applications, S7-1516 processors offer robust performance. Check our Siemens S7-1500 Controllers for availability.
Siemens to Allen Bradley PLC Conversion
Upgrading from Siemens S7-300/400 to Allen Bradley Logix5000 requires careful mapping due to architectural differences. Below are general recommendations:
- S7-300 (e.g., CPU 315-2 PN/DP): Aligns with CompactLogix L30x or L33x for mid-range applications with moderate I/O and Ethernet needs. Browse CompactLogix.
- S7-400 (e.g., CPU 416-3 PN/DP): Matches ControlLogix L73 or L75 for high I/O counts and advanced processing. Browse ControlLogix.
Key Considerations:
- Allen Bradley’s tag-based memory differs from Siemens’ fixed blocks—allocate tags strategically to avoid fragmentation.
- Convert Siemens Organization Blocks (e.g., OB1 for cyclic execution) to Logix tasks (e.g., Continuous Task).
- Ensure EtherNet/IP compatibility with Allen Bradley systems by adding appropriate modules. Shop Network Modules.
Expert Advice: S7-400 systems with large I/O setups benefit from ControlLogix’s rack-based architecture. Contact our team for a custom migration plan.
I/O Module Cross-Reference
Upgrading PLCs requires replacing I/O modules. Below are cross-references from Allen Bradley PLC-5 to Siemens S7-1500 I/O modules.
