A vb 485 issue

Time:09-16

I rookie, industrial control would do database development
Now is the unit of production on the temporary help me catch
Is the ship's equipment, monitoring software, is not very friendly to independently develop a software used to monitor the running parameters and alarm,
But the original software and hardware equipment can't move (exemption)
Main idea is by getting the original monitoring software to get data, develop a set of system displays real-time parameter values and alarm,
The original system was developed by vb, to find a database for the basic configuration information of the system, how can want to get to the real-time data?
If read data from the serial port parse again, one is too difficult, but can't cooperate with the original manufacturers,
Masters do you have any other good idea you implement this idea? Please give advice or comments

CodePudding user response:

Hope you said about the ideas and to solve the existing problems, and have a bit can not affect the original system is running, is very important!

zhoushan, ningbo side of the ship?

CodePudding user response:

Collection devices are generally modbus rtu protocol

CodePudding user response:

If you want to "real time", only reading data from the serial port,
Transmit data as long as it is not "encryption", then "sample analysis" basic is easy,
I think the "most difficult" point here or is it the "check code algorithm of the agreement,
If it is not "standard method", do you want to "pretend" original software instructions, can be very difficult,
But if you just "read data" (direct point is to "steal" ), and ignore its check code line,

CodePudding user response:

Visual data can only use a serial port debug tool to grasp, and then each packet is analyzed,
