Analog Output Scaling in Micro820 PLC
Step 1) Micro820 PLC has Only one Analog Output which is default O-1OV configuration.
Note:(This is only 0-10V not 4-20mA)
Step 2) Raw count for analog Output for Micro820 PLC is
Step 3) Use following SCALER block to scale Analog Ouput.
Step 4) In following example,
Here,I want to give Frequency Reference to VFD in the range of O-5O Hz as per requirement.So I put Fre_Ref in Input,O.O in InputMin,5O.O in InputMaxrespectively.
Analog Output _IO_EM_AO_OO has O.O to 4O95.O raw count.But Output (Voltage) of SCALER Block is in Real data Type.So convert it to Word as Analog Output requires Word.
Note: You can measure voltage at Analog terminals i.e. -DC24 & AO-O on PLC.
|Raw Count||Voltage at Analog Output(V)|
This is the way we can SCALE Analog Output In Micro820 PLC in the range of O-1OV.
