Example Set a high limit alarm (H) on alarm number 2 of
math channel 015. Set the alarm value to 85.0.
When an alarm occurs, output to the relay (DO
channel) at number 0105.

DO,0105
Description
• You cannot set this on a "Off" channel.
• If p3=Off, you cannot set p4 or subsequent
parameters.
• If p7 (p8 for logarithmic math) = Off, you cannot set p8
(p9 for logarithmic math).
• You cannot set DO channels or internal switches
whose output type is set to Manual as output
destination numbers.
