Q1: Is the 1756‑L62 still in production or has it been discontinued?
The 1756‑L62 was officially discontinued by Rockwell Automation on June 1, 2017 . It is no longer available for sale from the manufacturer and is now considered a spare/legacy part.
Q2: What is the direct replacement for the 1756‑L62?
The functional replacement is the 1756‑L72 controller. The replacement category is "Functional Replacement," meaning the L72 provides similar or enhanced capabilities, including larger memory and built‑in Ethernet ports .
Q3: What is the user memory capacity of the 1756‑L62?
The 1756‑L62 has 4 MB of integrated user memory and 478 KB of I/O memory .
Q4: What communication protocols does the 1756‑L62 support natively?
The controller includes a built‑in RS‑232 serial port that supports DF1 full/half‑duplex, DF1 radio modem, DH‑485, Modbus via logic, and ASCII protocols . Additional protocols (EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus) require separate communication modules.
Q5: Is there a safety version of the 1756‑L62?
Yes, the 1756‑L62S is the safety‑certified GuardLogix version, providing SIL3 safety control . The standard 1756‑L62 (non‑S) does not support safety‑related logic.
