Detection on an Analog Input, DAC and P2C Updates
Update Mode: Update on True and False
Criteria: Ch 5 example: Below Limit; Ch 4 example: Inside Window
In this example Channel 5 has been programmed with reference to one setpoint [Limit A], defining a low
limit; and Channel 4 has been programmed with reference to two setpoints [Limits A and B] which define
a window for that channel.
Channel Condition State of
Detect Signal
Action
True When Channel 5 analog input voltage is below the limit A,
update DAC1 with Output Value 0.0V.
5 Below Limit A
(for Channel 5)
False When the above stated condition is false, update DAC1 with
the Output Value of minus 1.0V.
True When Channel 4 analog input voltage is within the window,
update P2C with 70h.
4 Within Window
(Between Limit A
and Limit B) for
Channel 4
False When the above stated condition is false (Channel 4 analog
input voltage is outside the window) update P2C with 30h.
