Future auto detect
« on: August 21, 2014, 06:51:39 PM »
Does the Modbus gateway have enough processing power that it could in the future have an auto detect of the serial device(s) it is connected with?

How many slaves should it auto-detect?  Should it try every baud, parity, stop bit, etc for each slave?

This would seem to be a pretty slippery slope.  It could literally take hours for the MB-GATEWAY to boot up if it were to auto-detect with no restrictions.

More like a semi auto detect or how DS5 works on a serial connection. If I try to connect a GS3 and one setting is wrong it won't work.

The DS Auto-Detect for serial ports only tries Address 1.  It cycles baud rates on that one address, not on all 90 possible addresses.  I think Modbus has up to 247 possible addresses?  That would take a LONG time, like rlp122 said.
