Hi
I am designing a pressure controlled vacuum tank.
Software of ESP32 and
Nextion screen is OK

But I have problem when
I get digital input from (TMCB)
thermal magnetic circuit protector( schneider gv2me14)
When red fault contacts close I want to get information of fault of motor.  But esp32 reset itself .

32- ModBus Adapter Protocol

In some 3rd-party applications the terms "PNP" / "NPN" are used to describe the polarity of the control signal (whether positive +12V or ground 0V voltage is used as the control signal). The KC868-H32BS outputs +12V (or +24V) per each output channel to control the relay. If a relay module is used, it gets a 0V as a common control line and +12V signal per each channel. Is this configuration considered as "PNP" or "NPN" connection from the point of view of the relay module?

improvement:

1. add MQTT topic include "post password" function. Improved security for controller

   

2. add 8 channel sensor input ports for effective pulse width options. Such as a sensor trigger signal time, from 10ms ---1 second.

Hello! 

I installed KC868-H32B with our mqtt server.

Sometimes TCP Client Led(white color) is blinking. what is that mean? 

thank you!

improvement:

support send MQTT command control multi output by one command:
such as if you want to let KC868-D8 dimmer output1:50% output2:60% output3:70% you can send:
{"dimmer1":{"value":50},"dimmer2":{"value":60},"dimmer3":{"value":70}}
   

update BIN file firmware by "KC868 Controller Network Bootloader" tool.
