How do I examine a number of equivalent data points in several different devices ( ie each at different modbus address) simultaneously.
Reading datd sources
add the points to a watch list and look at them with your eyes to perform the 'examination'
add the points to a report and look at the plots to perform the 'examination'
@Chromeaccent to craigs point, what do you mean by Examine?
If you want to read data from different slave IDs then you simply add more data points under the data source and change the Slave ID to match.
Note, on Modbus serial all data points on the same serial line need to be in the same data source ( you can't have more than one data source using a serial port).
Let us know if that helps.
