I want to configure CI853. We are getting some 10 analog signals in an instrument.
This Particular instrument is connected to CI853. Inorder to read this 10 analog signals, can i follow the below procedure which i understood from reading some related manuals:
1) In Control Builder-> CI853->COM->Add Modbus
2) Define a Global variable of (datatype -dint)
3) Use MB connect, make enable as true and connect the global variable
4) Use MB read
Is this Procedure correct? Can someone help me with the steps in configuration of CI853?
Channel: Determine the position of your CI853 and then the port you are using on the CI853. Ex. If your CI853 position is 2 on the controller rack and you using port 1 then the Channel ID : 2.1 , for port 2 Channel ID: 2.2.
Partner: This should be the address set on the slave device from which you are trying to read the data.
MB Read: You need to look in to the register information provided by the device vendor from which you are trying to read data and define the start address and also the number of registers you need to read. Normally you need to read two registers for one analog signal and merge them using "floating integer to real" block to get the actual signal.
