Modbus master for testing Monarco HAT as Modbus TCP slave
This example is a Modbus TCP master for testing the Monarco HAT as Modbus slave. The Modbus TCP slave device (Raspberry Pi + Monarco HAT) is supposed to have the IP address 192.168.1.100.
Modbus registers
Monarco HAT input signals
| Register No. | Meaning | Data range |
|---|---|---|
| 0 | Digital inputs (LSB=DI1) | 0..15 |
| 1 | Analog input 1 (0..10V, 12-bit) | 0..4095 |
| 2 | Analog input 2 (0..10V, 12-bit) | 0..4095 |
Monarco HAT output signals
| Register No. | Meaning | Data range |
|---|---|---|
| 2048 | Digital outputs (LSB=DO1) | 0..15 |
| 2049 | Analog output 1 (0..10V, 12-bit) | 0..4095 |
| 2050 | Analog output 2 (0..10V, 12-bit) | 0..4095 |
