Example 2 This example shows a PID control program using PID(––).
Amplifier (See note below.)
Fan (Output word IR 111)
Heater (Output word IR110)
Temperature sensing element
(Output word IR 100)
Amplifier (See note below.)
#0 #1
AD001 DA001
CPU
Unit
Note Motors and heaters cannot be directly connected from an Analog Output Unit.
An amplifier (i.e., a current amplification circuit) is required.
