Figure 4-11 Procedures for forced DO signal setting
H0D-19 (Forced DO value) is used to set whether the forced DO function is valid. The keypad displays the
value in hexadecimal, after being converted to binary, the number "1" indicates the DO function is valid
and "0" indicates the DO function is invalid.
Parameters in group H04 are used to set the DO logic. H0B-05 is used to monitor the DO level status. The
keypad displays the level, and the value of H0B-05 (Monitored DO signal) read by the software tool is a
decimal number.
Example: To activate the DO function allocated to DO1 and deactivate DO functions allocated to DO2 and
DO5, set as follows:
As the number "1" indicates the DO function is valid and "0" indicates the DO function is invalid, the
binary value will be "110", which corresponds to the hexadecimal number "6". Therefore, set H0D-19
(Forced DO value) to 6 through the keypad.
