Communication Method
Single-send (communication cycle = transmission cycle) asynchronous communication
Transmission/communication error detection (hardware) provided.
Synchronous communication error detection not provided.
Automatic recovery function provided.
I/O Registers
Input/output using I/O registers and synchronized on the high-speed scan or low-speed scan
