Hi,
I'm new to modbus and i need some help.
I have to implement a modbus slave and master application in order to write more than 65353 coils.

any ideas?

You wouldn't be able to use the "standard" Modbus spec. You'd have to make some vendor-specific extension to the spec, or distribute the coils across multiple "virtual" devices or something like that...

Hello,

Does it have to interface to others (using the MODBUS specification) or only your custom applications?
