Using Industruino as a Modbus RTU slave
Has anyone used Industruino as a modbus slave using the RS485 comm port ? I have seen a Modbus Simple Master on the blog, and been trying with "simplemodbus_slave", and "Modbus" libraries since, with no success.
Any input on the use of the RS485 comm port appreciated.
Hi Didier, i've tested communication between 2 IND.I/Os over RS485, with Modbus RTU, one as Master, one as Slave, using those same libraries. Please see this blog post for details.
Yeah ! Just works fine as a slave ! that was one of the last remaining issues to use Industruino in BMS projects. Thanks Tom !!!

Great. This will save me a lot of trial and error sessions. I'll have a try as soon as I come back from vacation.
