Omron Analog input AD041 scaling problem

[rudra]

Dear All,

I require valuable suggestion for solving below mention problems.

I’m using Omron PLC Analog module AD041 for scaling pressure switch (0-15PSIG = 0.5-4.5VDC)

I’m using SCL scaling instruction

SCL : S = Source word = Analog Input Add ( 5)
P1 =Scaled value for point A ( 0 PSIG)
P1+1 =Unscaled value for point A ( 603 Analog counts at 0.5VDC)
P1+2 =Scaled value for point B ( 15 PSIG )
P1+2=Unscaled value for point B ( 5500 Analog counts at 4.5VDC)

But I’m not getting scaled output from the SCL (Result word )

Please let me what could be the problem in program…

Attached is the program ladder fro your reference..
Thanks!

Hi. look in the manual some of the P1x have to be in HEX format

Hello,

Thanks for the reply,

I tried in Hex format problem remains same..

But if i put 50 value in P1+2 =Scaled value for point B it will work .. but i can't understand if 15 in P1+2 scaled output will be constant..

Have a look at this - it appears to work correctly in the simulator - I will try it on site later this week.
It scales 4-20ma to 4.00/9.00.
The description of the tags will indicate what you need to do.
This is for a CJ1 set to 0-4000 = 4-20ma.
