- EtherNet/IP Compatible Network Unit DL-EP1 User’s Manual (SK-1000) -
A value to be read or written is specified as on/off status of the bits
representing the value converted into binary.
When the read data is "6":
The decimal number "6" is represented in binary as "0110".
As a result, the sensor amplifier of the read data is set to "NPN output" and
"analog output of 1 to 5 V".
*8 Operates as "off" only when input off (0) is written and the external input is off
for both cable and cyclic communication.
*9 When a value is written to an expansion unit, a writing error occurs.
*10 To reflect the settings written for the function selection of external inputs 1 to 4
(0392H (914) to 0395H (917)) to the sensor amplifier, you need to set the
external input setting (0391H (913)) to 1 (User setting) or to operate the sensor
amplifier's button to set the external input to "User setting".
