<![CDATA[Use Mango as MODBUS slave]]>Is it possible to setup a slave over TCP with the modbus module?

Because my devices cannot be contacted by the server (I am using GPRS so they don't have a IP that is visible externally) I was thinking I could get the device to poll a virtual modbus connection running on the server and set registers etc. I can also use this to read back setpoints etc.

Is this possible?

This would be a great addition to Mango as it would give an alternative option for devices that are on the internet but without a visible IP address, GPRS based devices for instance, to be able to send and retrieve parameters.

I use this very method with VTS for a commercial application I have with an oil company. The binary transmission is also smaller than using HTTP.

I can see some real potential uses for Mango in my commercial ventures, for some of the smaller projects were a full blown SCADA system is beyond their budget. Right now, it is purely for development and home automation.

Right now, Mango can not act as a modbus slave, only a master. We have it planned as a new feature to add but not sure exactly when it will be available.

Joel.
