For a 16 firmware

[admin]

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

[admin]

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.
