Basic information
BK7500 15
Function type of the channel Assignment level
1. Analog outputs byte-wise assignment
2. Digital outputs bit-wise assignment
3. Analog inputs byte-wise assignment
4 Digital inputs bit-wise assignment
Analog inputs/ouputs are representative of other complex multi-byte signal
bus terminals (RS232, SSI sensor interface, ...)
