i have a couple of RTU based I/O units which i reach via a MODBUS TCP/IP 485 gateway device.
using another modbus master and a polling interval set to say 1 sec, you can see the COMM LED indicators cycling nicely and all is well.
if i then disable that master and try mango as the MASTER, with a 1 sec update, the polling is very erratic and quite often misses the beat/rhythmn and shortly after comms falls over, with data source might not be updating etc.
i then have to disable and enable to source.
i never did get to the bottom of this but as it was the mango wasnt resilient enough to use.
but i have need to use mango this time so need to nail this issue.
any pointers as i try to revive this and repeat the problem?
could the polling be compromised by other sources being lazy?
if this was the case, i'd still like to see datasource polling by cron, that way the user can segregate sources completely.
