| Standalone operation | No: requires a Modbus RTU master |
What it is
moduleX is an industrial modular I/O expansion platform. It adds distributed digital and analog I/O to any controller with a Modbus RTU RS485 port. It is not a controller: it has no control logic of its own.
Can moduleX work without a PLC?
No. moduleX requires a Modbus RTU master (such as M-Duino, ESP32 PLC, Raspberry Pi PLC or GateBerry) to function. It cannot execute control logic independently.
Compatibility
| Compatible with | M-Duino, ESP32 PLC, Raspberry Pi PLC, GateBerry, any Modbus RTU master with RS485 |
| Communicates through | Modbus RTU over RS485 daisy-chain |
| Typical role | Remote I/O expansion: master reads and writes moduleX points as distributed I/O |
