Just wondering is it better to use scheduled or triggered messages in DH485 network. I have 6 slave stations and one master slc. Now slaves are writing to SLC when they need (no scheduling). At some point network becomes clogged and two scada computers are performing very slowly. Now I want to switch program in SCL to call one station every three seconds. This I can do if one message triggers another or timer triggers another message every three seconds. I think first method uses lot more bandwidth. Does anyone have better idea!



Thanks.
