Last version: v0.0.4
The library is a wrap of internal library Modbus_Master.
In the library, requests are grouped for each network device separately, and devices are sequentially polled. Each network device has a local data buffer.
If you need to poll several devices, this library will help you reduce the amount of code, organize the polling order.
Before diving into the library I recommend to read: Description of Modbus_Master: Overview of the Modbus RTU communication (S7-1200, S7-1500)
Example: link How do you establish MODBUS-RTU communication?
