Ladder Diagram
As shown in the ladder diagram below, when initialize pulse special internal relay M8120 is used for the ANST macro in
parallel with another instruction, load M8120 again for the other instruction.
Note: The above ladder diagram is only an example and should be modified as required.

I/O M
M8120 is the initialize pulse special internal relay.
When the CPU starts to run, ANST stores parameters to
data registers to configure analog I/O modules and Q30
is turned on.
When I0 is turned on, analog input data is moved from
D676 to D1000.
The temperature is compared with the alarm tempera-
ture of 100°C.
When the temperature is higher than 100°C, Q30 is
turned off.
When the temperature is not higher than 100°C, Q30 is
turned on.
Analog input data of –500 to +1500 is converted to 0 to
2000.
Analog input data of 0 to 2000 is converted to 0 to
4000.
Analog input data of 0 to 4000 is moved to D772 (ana-
log output data) of the analog output module.
