I need to use the 0x14 command of Modbus Protocol in order to get some “historical data” from my device. This command is the only way provided by my device to obtain those registers.
Hi,
The current version of Modbus driver can not send custom (non standard) commands.
Imagine it is implemented. What format of the response will be received? How to decode the response and process it?
I came across similar situation:
a device uses Modbus, but the device provides events. I can receive binary data of those events. So I had to implement a separate driver to process received events and store them.
Thanks for the answer.
We’ve decided to implement a driver for that issue in the future. We’re focusing on the real time acquisition and it goes great with the software.
