I'm trying to find out the maximum number of slaves a modbus RS485 network can support. I saw this:
The maximum Nodes on one RS-485 network is 32. Maximum distance will depend on the applied speed as well as the cable type.
The maximum Modbus Slaves per one multi-drop network is 255.
What's a modbus node? I thought it was only masters and slaves...
I thought the max number of slaves is 247 (?). Here it says 255...

Please advise. Thanks.
