Mov *dm (omron Plc)

Dear All,

There is a MOV logic instruction in a Omron PLC where I dont understand the relation of *DM moved to HR.

See the attached file for example.
If I enter #433 into my *DM90, why is my HR value is #800?

Please advice, thank you.

*DM90 - the * indicate the addressing is indirect. In actual fact it is moving the contents of channel 433 to your HR.

Just to be clear...

It will move the contents of "DM433" into HR80.

If indirect addressing is your goal then I suggest reading this tutorial on Indirect Addressing in Omron PLC's.
