Note 1. Input mode setting allows selection between 16-point input and 15-point+1 error input.
2. Input mode setting allows selection between 32-point input and 30-point+2 error input. Refer to 2-2
Switch Settings.
3. The maximum transmission distance of the B7A Interface Unit varies with the transmission delay time
and the method of wiring. Refer to 3-1 Connections to B7A Link Terminals for details.
4. Minimum input time is the minimum required time to read an input signal from the CPU. The ON/OFF
signal range from the CPU to the B7A Interface Unit's output bit should be larger than the minimum input
time.
