The status of each output assigned to the controller is converted to the corresponding decimal data
and then is sent to the host computer. Convert the decimal data sent from the controller to the
corresponding binary data (bit image) to confirm the status.
Bit number Assignment terminal Output type Terminal status
b0 OUT1
b1 OUT2
b2 OUT3 Control output
b3 OUT4 or
b4 OUT5 Alarm output
b5 OUT6 0: Open 1: Close
b6 OUT7
b7 OUT8
b8 ALM1
b9 ALM2 Alarm output
b10 ALM3
In case of current output (0 to 20 mA DC, 4 to 20 mA DC), these data becomes invalid.
Example:
Bit images (Decimal number) (Binary number)
Open/Close status 1792 = 1 1 1 0 0 0 0 0 0 0 0
Bit number b10 b9 b8 b7 b6 b5 b4 b3 b2 b1 b0
If any defect (welding, etc.) is found in the relay located inside the instrument, the output
status may differ from the relay contact status.
2
The RUN/STOP terminal and memory area transfer contact input (DI) terminal statuses are
converted to the corresponding decimal data, respectively and then are sent to the host computer.
Convert the decimal data sent from the controller to the corresponding binary data (bit image) to
confirm the status.
Bit number Input type Terminal status
b0 RUN/STOP terminal status
b1 DI1 terminal status
b2 DI2 terminal status 0: Open 1: Close
b3 DI4 terminal status
b4 DI SET terminal status
Example:
Bit images (Decimal number) (Binary number)
Open/Close status 18 = 1 0 0 1 0
Bit number b4b3b2b1b0
