Setting/status command parameters

• For the communication methods using setting/status parameters,

see

"Reading/Writing Settings or Status of a Sensor Amplifier" (page 3-23).

• To reduce the number of writes to the EEPROM, a write command is executed 2

seconds after it is received. If another command is received within 2 seconds, the
DL-DN1 waits for another 2 seconds before executing the two commands simulta-
neously. After the writing completes successfully, the "EEPROM writing result"
parameter becomes "successfully completed (1)". For example, if commands are
received continuously every second, they will not execute because the DL-DN1
remains "currently writing (0)". 2 seconds after the last command is received, the
commands received will be executed simultaneously.

• If data with a decimal point is used for a parameter range, ignore the decimal point

and read or write the data as an integer. For example, to write a HI setting value
(BANK 0) of "+1.235", write "+1235".

• Attribute R: Read; W: Write; R/W: Read/Write
• N: ID number of sensor amplifier; for example, if the ID number is 13, then N x 10 +

3 -> 133 (DEC).

• The data types are DINT unless explicitly specified.
