Hi,
When I want to test the Realtime Group followed the tutorial –Realtime Group, I found this error. Motor02 is Errored. （I cannot find more info from the gateway log. it only shows info below.
I confirm the problem is caused by update/select “key/value pairs”
Because if I select insert new row, … They all worked.
Can you explain why. I did what the tutorial told me to do.
Is it a bug or I did something wrong. (I am using 8.1.48)
Thanks.
I've never used the key/value pairs option. Have you tried using the "custom" option?
You are telling the Transaction group to update the row of data based on the fact that the column motors_1_ndx is a value of 2. If there is no value of 2 in that column for the data to update, what do you expect the group will do?
I should really have another cup of coffee. Sigh.
I'm with @jordanCclark. I have better luck with custom.
He has Insert row when not present checked.
I usually have better luck getting it to work using custom vs key/value
I did try the Custom, it works. I am just curious why it doesn’t work based on the tutorial.
