Frequently Asked Questions

Q: Does the 1769-L31 support Ethernet/IP?
A: No, this is a serial-only processor. For Ethernet/IP communication, use the 1769-L32E or 1769-L35E.

Q: How many I/O points can it handle?
A: Up to 16 local 1769 modules; the total I/O count depends on the module types used.

Q: Can I use it for motion control?
A: It supports basic motion via local I/O or serial devices but does not support Integrated Motion on EtherNet/IP.
