modbustcp

Hi

Is a modbus TCP or RTU slave device API available?

Also I noticed that the modbustcp link appears to be dead at developer.sierrawireless.com/en/ … _API.aspx#

Is the modbus library used proprietary to Sierra or is it based on open source code?

Kind regards

Edward

Hi,

Thank you for noticing the dead link for modbustcp doc, I’ll forward that to people working on ALEOS AF web resources.

Regarding modbustcp, it is an implementation of modbus TCP, TCP/RTU and TCP/ASCII made by Sierra Wireless.
I’ve attached a raw version of the modbustcp API doc, but the official one should be up again soon.

Thanks for the information.

Is modbus slave (server) functionality available from the API?

I can only find master functionality in the API manual

Kind regards

Hi,

For now, only modbus master is available in the API, in modbus TCP as well in modbus “serial”.
