do you want KC868-A16 work as "MASTER" or "SLAVE" ?
just want to know A16 connect to what device? A16 read data from device? or device control A16?
Read data from other modbus devices hvac alarm point temperature humidity thanks
new "KCS" will let A16 work as "SLAVE" , controlled by third device, if you want A16 work as "MASTER", you need to write arduino code by yourself, because different RS485 device have different protocol.
I need to read data point from hvac device how to read data how I define alarm points modbus address
To relay 1 to 16
I have data point list just want to know how to use in kcs
i have said, "KCS" not support use by this way. A16's RS485 address can set by A16's config webpage.
