### 4. Functionality and Applications

Operating Principle:
The EX9051‑MTCP connects directly to an Ethernet network and acts as a Modbus/TCP slave device. It exchanges I/O data with SCADA systems, PLCs, or PCs using standard Modbus function codes. Each digital input can be read as a discrete bit or configured as a counter. The two dedicated counter/frequency channels provide precise event counting or frequency measurement up to 4.5 kHz. Digital outputs can be controlled individually or used to generate pulses for actuators or alarms.

Typical Use Cases:
- Factory automation and machine monitoring.
- Remote digital signal acquisition (switches, sensors, proximity detectors).
- Event counting and frequency measurement (flow meters, encoders).
- Control of indicator lamps, relays, or solenoids via digital outputs.
- Integration with HMI/SCADA systems over Ethernet.
- Distributed I/O expansion for PLCs using Modbus/TCP.

Compatibility:
Works with any Modbus/TCP‑compliant master, including Wonderware, iFIX, Citect, LabVIEW, and custom applications using ExpertDAQ DLL or ActiveX libraries.
