Frequently Asked Questions
- Q: What can the high-speed counters be used for?
A: They are perfect for counting pulses from encoders on conveyors or tracking product speed. - Q: Can I connect thermocouples directly to this controller?
A: Yes! The built-in analog inputs support many thermocouple types (J, K, T, etc.) without extra modules. - Q: How many additional I/O modules can I add?
A: You can expand the system with up to 4 additional 1769 series I/O modules. - Q: Is this controller good for simple motion control?
A: Yes, it can control up to 2 axes of motion over Ethernet for basic positioning. - Q: What is the advantage of having two Ethernet ports?
A: One port can connect to your factory network, and the other can daisy-chain to other devices, saving on switches.
