• These registers are used to specify data for analog output from the
analog control boards of the D/A converter boards or analog I/O boards.
• The range of digital value to specify analog output depends on the type
of analog control boards as follows:
<When D/A converter boards is installed>
Range of digital data for specifying analog output (10 bits): K0 to K999
(0 to 20 mA/0 to 5 V/0 to 10 V)
Note:
• Be sure to specify data within the range of K0 to K999.
- If data K1000 to K1023 is specified, analog data a little bit more than
the maximum rated value (20 mA/5 V/10 V) is output.
- If data outside K0 to K1023 is specified, data is handled
disregarding data in bit positions 10 to 15.
<EXAMPLE>
If K-24 is input, analog data is output regarding it as K999.
Data configuration when K-24 is input:
Bit position
15 12
• •
Binary data
1 1 1 1
Data in bit positions 10 to 15 is ignored.
<When Analog I/O board is installed>
Range of digital data for specifying analog output (8 bits): K0 to K255
(0 to 20 mA/0 to 5 V/0 to 10 V)
Note:
• Be sure to specifying data within the range of K0 to K255. If data
outside K0 to K255 is specified, data is handled disregarding data in bit
positions 8 to 15.
<EXAMPLE>
If K-1 is input, analog data is output regarding it as K255.
Data configuration when K-1 is input:
Bit position
15 12
• •
Binary data
1 1 1 1
Data in bit positions 8 to 15 is ignored.
