FAQ
Q: How many I/O points can the 2MLI-CPUH control?
A: It supports up to 6,144 installable points. Contact memory reaches 131,072 points.
Q: Can I migrate existing ladder code to this CPU?
A: Yes. It supports Ladder, SFC and ST under IEC. Review function block mapping before you migrate.
Q: Which scan mode suits fast machine cycles?
A: Constant scan gives fixed cycle time. Use direct command mode for time-critical outputs.
Q: Is 3.5MB memory enough for large projects?
A: It fits large ladder and ST programs. Plan retain areas early for recipe and recipe backup data.
Q: How do I choose a spare CPU for an obsolete line?
A: Match the exact part number 2MLI-CPUH. Check rack type and firmware level first. Ask us for cross-reference help.
