Experimental Physics and Industrial Control System
Hi Donny,
thanks for the files.
I wanted to check if and how your records are connected. If you are FLNKing the devices or if they are SCANned
independenty or I/O Intr or anything else.
What you have looks "normal" to me.
I see that all devices use the same (serial?) port, thus a timeout for one device delays the others.
Check your LockTimeout against your ReplyTimeout. I would make LockTimeout > ReplyTimeout * number of devices.
Otherwise your other queued device lose patience while one or more device wait for timeout.
Make ReplyTimeout not much longer than necessary or you waste too much time when d device goes offline. I would measure
how long a device typically takes to reply on the slowest commend and multiply that by 2. If you then get timeouts from
a running device increase it a bit (e.g. by 25% or so). Then multiply this by the number of devices sharing the same
port (here 12).
