RS485 communication

[mweisbr]

Hello,

I have some problems with the RS485 interface and hope you can help me.

in the following code:

https://github.com/CONTROLLINO-PLC/CONTROLLINO_Library/blob/master/MAXI/DemoRS485/DemoRS485.ino

describe the use of the RS485 interface. How would I have to change the code so that I first send a data byte

for example

Code:

byte a_reset[] = { 0xAA, 0x02, 0x06, 0x00, 0x02, 0x4D, 0x00, 0x01, 0x00, 0x8F, 0xE1, 0x55 };

via the Controllino/Master via RS485 and only then receive the answer from the device/slave?

Thank you

Yours sincerely

Martin
