The 1768-L4x CompactLogix system combines a 1768 backplane for communication and motion support and a 1769 backplane for I/O support. The 1768 controller is designed for integrated motion and more complex communication requirements than the other CompactLogix controllers.
The 1768-L4x system provides
- both a 1768 backplane and a 1769 backplane.
- 1768 backplane support of the 1768 controller, the 1768 power supply, and a maximum of four 1768 modules.
- 1769 backplane support of a maximum of thirty 1769 I/O modules.
- one RS-232 serial port.
