Digital I/O and serial Com-Server in a single device
The W&T 57731 connects 12× DI + 12× DO to a 10/100BaseT Ethernet network. It enables monitoring and control via a web interface and integration into higher-level systems using OPC UA, MQTT, REST or Modbus TCP.
Do you need to select or order W&T 57731?
Please send us the required quantity and a description of the wiring configuration. We will check availability and suitable accessories.
Usage
The module is used for collecting status signals, fault reporting and remote control within industrial or technical infrastructure. Statuses can be displayed in a browser, transferred to a visualisation system or used in pre-defined actions.

Signals, communication and events
- In addition to digital signals, a separate RS232 port with Com-Server functionality is available. It supports virtual COM ports, Box-to-Box, TCP/UDP, FTP and Telnet; the serial port has a DTE configuration and a baud rate of up to 230,400 Bd.
- The web interface supports HTTP/HTTPS. OPC UA, MQTT Publish/Subscribe, REST and Modbus TCP are available for integration; individual services and the necessary permissions are configured on the device.
- Up to 30 actions can be configured, such as an email, an SNMP trap, an output switch or an HTTP request. SNMP supports versions V1, V2 and V3.
- Box-to-Box mode transfers switching states between suitably configured Web-IO devices over the network. Correct mapping of inputs and outputs is part of the configuration.
- The inputs support 32-bit event counters. The parameters for input voltage, switching threshold and current consumption are governed by the table for this model.
Commissioning and accessories
Check the module’s power supply, common conductors, polarity and output loads. Once connected to the network, configure the IP address, access rights, required protocols and event responses. Before connecting the load, check the wiring in accordance with the manual for the specific model.

Frequently Asked Questions
How many physical channels does this model have?
In addition to digital signals, a separate RS232 port with Com-Server functionality is available. It supports virtual COM ports, Box-to-Box, TCP/UDP, FTP and Telnet; the serial port has a DTE configuration and a baud rate of up to 230,400 Bd.
Do I need a special programme to operate it?
A web interface is available for basic monitoring and control. A supported protocol and its access rights are configured for the host system.
Does ‘Box-to-Box’ refer to a fixed response time?
No. The typical response times shown in the table do not guarantee the overall response of the entire network. The result also depends on network communication and the configuration of both devices.
