Hello,
After several reading and rereading of the RSI notice, I still have trouble understanding the hardware and communication part.
Let's take a concrete example: I need to maintain a distance of 1cm between the TCP (where the sensor is placed) and an irregular surface ( Z axis correction only).
I have an acquisition unit that makes sensor data available on a computer.
A plugin from the manufacturer of the datalogger is responsible for making the data available in any form on the computer (we will request and pay for the development of the plugin).
The control panel is connected by USB to the computer.
The computer is connected in Ethernet to the RSI.
The RSI needs to recover a single external information: the sensor data generated by the acquisition unit (between 0 and 50mm, analog data).
Already if I understood correctly the diagram of principle is attached.
I should also write two XML models:
Send.xml
<SEND>
<ELEMENTS>
<ELEMENT TAG = "Distance" TYPE = "DOUBLE" INDX = "1" />
</ ITEMS>
</ SEND>
Receive.xml
<RECEIVE>
<ELEMENTS>
<ELEMENT TAG = "Distance" TYPE = "DOUBLE" INDX = "1" HOLDON = "0" />
</ ITEMS>
</ RECEIVE>
Where to place these files? Who shares what and how (computer and RSI) or (RSI and KRC4) ?
Who is the sender? Who is the receiver?
How can the RSI recover information from the computer ? Need I developp my proper serveur ?
Thank You !
