environment: forte: 1.8.4, 4diac ide: 1.11.2
I am following the doc "OPC DA": https://www.eclipse.org/4diac/en_help.php?helppage=html/communication/opc.html,
especially, "fbInputItems/fbOutputItems: items to be added, items should be separated with a comma"
so I use the FB CLIENT_1,
set the ID as: opc[127.0.0.1:opcserversim.Instance.1:2000:0.01:T1,T2,T3:Q1,Q2,Q3]
set the SD_1 as: REAL#11,REAL#22,REAL#33
But the result I observed in OPC simulation server is: the item T1 was set to 11, but the other two items T2 and T3 was set to 0, not 22 and 33. Have you ever tested this function?
