Frequently Asked Questions

Q: What’s the difference between the L36ERM and L33ERM?
A: The 1769-L36ERM offers 3 MB memory versus 2 MB on the L33ERM and supports up to 48 EtherNet/IP nodes, compared to 32 for the L33ERM, making it suitable for larger, more node-intensive systems.

Q: Does this controller require a battery?
A: No. The L36ERM uses an internal energy storage module to retain program data and SD card contents during power loss.

Q: How many motion axes can it control?
A: It supports up to 8 axes of Integrated Motion on EtherNet/IP without additional motion modules.
