Thanks. Honestly it's obvious.
If there were no restriction (or 247 as upper limit) for slaves in Modbus TCP Master - I would have no questions.
But my question not about specification Modbus TCP or TCP, I just wonder is this correct to use many Modbus TCP Master under same Ethernet Adapter node.
Maybe it's unexpected-from-user solution and it will create problems for IO-drivers or something other...
So I just want to get some advice from developers.
Whooa,no response from Dev?
I have a simmilar newbie question….. How many slaves/channels can be assigned to a Codesys device ?
(Docs and googling did not reveal this in a second or two.)
From the above posts I get hint of 64 slaves per master.
Multipple masters are possible.
But how many channels per slave?
And what is the total max? Depending on system memory or what?
Probably a number that will fit in a ip subnet of 200+ device will be sufficient. Then again there may be multipple device ids behind an ip.
