How to connect Delta DVP-12SC Type plc with Bar code scanner?

Best with electric wires (cable) and if need to be removable use also plugs.

Same answer for the next posts.

what type of output get through bar code Scanner?

Please see the documentation for your particular example (several output types are possible).

Also, please do not duplicate posts, unless you are building a fence.

Quintuplicate posts; I think this is a new record.

Maybe the Delta DVP documentation tells how to interface it with various devices?

Rather give more detail of your problem than giving the same skimpy detail many times.

What do you intend to achieve?

Do you intend to switch a relay when a specific or range of bar code stickers pass the scanner?

what type of output get through bar code Scanner?

There are different schemes but basically it returns the character/number string which the code represents follow by a line feed set.

If it is a USB one the output can be used as if you typed the string on a keyboard and hit enter. [Try it on a PC].

It could also be a keyboard wedge type (wedged between the keyboard an the PC)

In am not a PLC user , The way I see it you may have to use a PIC or CPU to translate the code to suitable signal lines to activate the PLC differently depending on the code.

If you look at the bar-code tag on products in the shop the number printed below the bars will be returned. The PIC or CPU will then have to identify the unique string and select the response.
