H0d.18 is used to set the forced DI level. The keypad displays the value in
hexadecimal. After the hexadecimal value is converted to a binary value, the
value "1" indicates high level and "0" indicates low level.
The DI logic is defined by parameters in group H03. H0b.03 is used to monitor
the DI level status. The keypad displays the level, and the value of H0b.03
(Monitored DI signal) read in the software tool is hexadecimal.
