Frequently Asked Questions

Q: What's the difference between the 1756-L62 and 1756-L63 controllers?
A: The primary distinction is memory capacity—the L62 provides 4MB user memory while the L63 offers 8MB. Both share identical I/O capacity and processing speed, so selection depends on program complexity and data storage requirements.

Q: Can this controller support safety-rated I/O modules?
A: The standard 1756-L62/B handles conventional I/O. For integrated safety applications up to SIL 3/PLe, consider the GuardLogix safety controller series which maintains the same chassis compatibility.

Q: How many EtherNet/IP devices can connect to this controller?
A: The integrated EtherNet/IP port supports up to 250 TCP connections, accommodating extensive distributed I/O networks, HMI panels, and third-party devices on a single controller.

Q: Is the controller compatible with legacy 1756 chassis and power supplies?
A: Yes, the 1756-L62/B maintains full backward compatibility with all ControlLogix chassis (1756-A4 through A17) and power supply modules, protecting existing infrastructure investments.
