H32BS and COLB communication

[autind]

1st - To use KCB868-H32BS connected to KCB868-COLB, with RS485 - Modbus communication, what network configurations are necessary?

2nd - Using the COLB with mqtt protocol, how to read the analog values?

3rd - To use COLD using SCADA software, which mosbus is it possible to use, RTU or TCPip?
Is it possible to configure the master-slave mode and the controller Id?

1: if you let H32BS connect to COLB by RS485, without network is no problem. if H32BS connect with network cable, that is in order to KinCony's software.

2: if use by MQTT, what application do you want to use?

3: if you integrate COLB with 3rd software platform, use TCP or MQTT is avaible. COLB not support integrate with MODBUS protocol, H32BS support integrated by MODBUS by "slave" mode.

1: se você deixar o H32BS se conectar ao COLB por RS485, sem rede não há problema. se o H32BS se conectar com o cabo de rede, isso é para o software da KinCony.

2: se for usado pelo MQTT, qual aplicativo você deseja usar?

3: se você integrar o COLB com a 3ª plataforma de software, o uso de TCP ou MQTT está disponível. COLB não suporta integração com protocolo MODBUS, suporte H32BS integrado por MODBUS pelo modo "escravo".

Estou usando o Kincony Smart Board Controller, com comandos IFTTT, mas o H32BS não responde....

can you take a video of your question?

pode fazer um video da sua pergunta?

does not respond to modbus command....
What is the calculation used for CRC code?

[admin]

KC868-COLB's RS485 use for KinCony's RS485 energy meter, now you use RS485 connect to H32BS, do you want use COLB automatic control H32BS output? here is video tour: https://youtu.be/Obo3YHj2A6k
i don't know what function do you want? can you say clearly?

[autind]

In the demo video you get an example of a modbus command, what is the calculation used for the CRC value, this heat changes with each command...?
To use mqtt and Node-red with COLB controller, how to read analog values?
To control the outputs of the H32BS through the logical values of the COLB, via rs485, must the ethernet and wifi network be disconnected?

[admin]

1. by CRC16 modbus RTU. there are some modbus tool will auto add the CRC code for command.
2. see this document about read analog data for COLB by mqtt: https://www.kincony.com/download/KC868-C...ommand.pdf
b. Read all analog input sensor data payload={State=A_FF}
feedback: “{ A1”:“{ value”:0.0},”A2″:“{ value”:0.0},”A3″:“{ value”:0.0},”A4″:“{ value”:0.0},”A5″:“{ value”:0.0},”
A6″:“{ value”:0.0},”A7″:“{ value”:0.0},”A8″:“{ value”:0.0},”A9″:“{ value”:0.0},”A10″:“{ value”:0.0},”
A11″:{“value”:0.0},”A12″:{“value”:0.0},”A13″:{“value”:0.0},”A14″:{“value”:0.0},”
A15″:{“value”:0.0},”A16″:{“value”:0.0}}
3. if your H32BS automatic control by COLB via RS485, not need ethernet or wifi.

example: if the controller is connected to the network and receiving commands through Node-red (mqtt),
does this interfere with rs485 communication?

qual a tensão para entradas análogicas?

[admin]

if use MQTT by network, not need to use RS485, only use ethernet cable is ok.
