ASCII to ModBus

ASCII to ModBus

ASCII to ModBus

(OP)
I have a small problem.  We have a device that outputs a simple alarm via ASCII code, but my Plant Network is ModBus RTU.  Does anyone know of some Local (N. American) products that are tried tested and true?

RE: ASCII to ModBus

The output of your ideal device is Modbus RTU, the input is ? ? ?

RE: ASCII to ModBus

I read the post to indicate that he has a device that outputs a text string and would like a device that upon recieving the text string prepares some sort of Modbus RTU message.  I say prepares a message because Modbus RTU is a master slave protocol and the device would need to be polled by the master. This won't be a problem since he is using a BMS.

I don't know of any devices that can be purchased off the shelf to accomplish this, but it wouldn't be too awful difficult to design one with a little microcontroller.
