Writing Software Drivers for legacy equipment,Īnd as a troubleshooting tool for existing systems. This is very handy when setting up new equipment or software, Use an '=' and '#' as the first character of the message.
This ALSO works for the 'special' RS-232 devices that
The KEY is that the Serial Parameters must all be the SAME:īaud, Parity, Bits, Stop-bits, etc. The use of 1-WIRE digital sensors eliminates the influence of cable length on the measurement process that. Parse them, and, if desired, provide a Hard-Coded response. Measuring Module 1-WIRE to MODBUS-RTU ADA-401WP. Just listen on a Serial Port and capture the Requests, I've come up with an "RS_232-485 Slave Simulator" in LabVIEW that will YES, this can be done, but it helps if you have the exact equipment to Verify the operation as you are developing the code. I think you'll have to try it and perform a realistic test that's long enough to see whether it works well enough for your purposes. How bad this will be depends on the robustness of the modbus slave implementations and alternating between 7 bits and 8 bits character formats may help mitigating this problem. This can trigger them to reply with an error message, which can effectively knock out your communication. This can lead to slaves being triggered by a byte transmitted in the other protocol they mistakenly interpret as their slave address.
