encoder input to analogue output

encoder input to analogue output

encoder input to analogue output

(OP)
Hi,
System
AB SLC 5/03.
1746 - HSCE Card for encoder 1024ppr encoder input.
1746 - N104V 2channel analogue input/output card.
Drive roller dia = 100mm (~4inch)
The machine drive roller pulls material through the machine at about 10m/min

I need to measure the speed of the machine via the encoder and send a 0-10V output to another drive card via the analogue output card.
I assume I will have to convert ppr to rpm and then to a value that the analogue card can use for the 0-10volt output.

I would appreciate any help / suggestions on how to achieve this using the above kit.

Regards,
mrbj

RE: encoder input to analogue output

"convert ppr to rpm" isn't exactly the solution.

It is a lot simpler. There should be (I do not know the AB system) an instruction that handles the encoder input on the HSCE card and puts it into a variable. It would then be a very simple thing to output that variable to an analogue output on the N104V card.

Ask your PLC programmer to do it. He knows how to.

RE: encoder input to analogue output

The Encoder count can be converted to an integer or DP Integer then you can do the needed scaling etc. Before outputing that to the Analog out card.
