I’m using the async option and a trigger on an action item. In fact it take a couple of condition before starting this group. More specificaly, an action item is reading a value in the database and an OPC item is confirming that the table use by the group is ready to operate. The trigger is on an other action item who’s checking if both condition are good. The table in the database read by the first action item is the same used to write in the PLC and it is the one builded previously by the stored procedure. Can that cause the problem?
I found that if I don’t select the “Only execute group once…” option I can write in the PLC but the group is execute three to five times and I still have the startup error.
Is anything else I can try?
Thanks in advance
