I have a counter, every object will add one, I want to see on the computer on the counter now how many records in the data, how to implement;

CodePudding user response:

This we know
You have to ask manufacturers to counter communication protocol

CodePudding user response:

But I there is no interface on the counter, so I don't know how to do, not to say that the agreement of the problem

CodePudding user response:

Individual ask us, this is your equipment, ask purchasing and let them contact

Not your equipment, seek nameplate, according to the nameplate contact manufacturer,

CodePudding user response:

This does require communication protocol, otherwise how to commune with counter

CodePudding user response:

Write a serial communication software

CodePudding user response:

That you can consult a hardware engineer, he LED display signal using a device, take a thread and then buy a ADAM4055 current signal can be converted to a computer or other equipment can be identification signal equipment, you can do the PC serial communication using count

CodePudding user response:

If there is no communication interface counters, that you only use the machine vision method to implement.

CodePudding user response:

If there is no communication interface counters, that you only use machine vision method to implement.

CodePudding user response:

I think their transformation under the counter, connect line and data version of the counter, and then the data edition through the front-end ports and computer connection above, but specific how to achieve not too clear, someone has done

CodePudding user response:

The key is we don't know what you said the line is a line

Is digital or analog signal

Suggest you understand the first question, at the same time, suggest you find someone who learn automation professional look
