Are there any tips/tricks to get the best communications performance with an SLC 5/04 connected to Ignition via DH±->DHRIO–>ENBT/A? There are also a couple very old RSView HMIs on the DH+ network. There used to be more on it, but we’ve moved everything else off DH+.
We are gradually migrating from RSView to Ignition on this system and are now reading a lot of tags in Ignition.Presently, these are setup in a direct scan class at one second. Lately we’re noticing a few performance issues with the SLC 5/04 (does not affect other PLCs connected to Ignition):
1 - Some tags can take quite a while to show good quality when opening a new window
2 - Communication with SLC 5/04 via RSLogix 500 is slow (obvious when uploading values before save)
3 - RSLogix 500 has difficulty connecting to / staying connected to the SLC
In Ignition 7.9.8, the status page for this device is not very enlightening with status: “Hello world”
Any suggestions/guidelines before playing with scan class(es)?
