The evolution of Modbus on devices with universal I/O
- Available isolated digital and analog I/O
- RS485 high-speed interface
- Enhanced – Modbus RTU protocol
- Configurable on fieldbus
- Device identification on bus
- CoDeSys integration for Web-PLC
- Advanced management tool on PC
- Dimensions 17.5 mm on DIN rail
The modules of the EX series are compatible with all devices with Modbus standard protocol. Used as I/O expansion of the CoDeSys Web PLCs, it can be achieved extremely higher communication performance to what is normally possible to obtain with other Modbus devices. Also, the modules, while being compact in size, have a high density of I/O and a great flexibility of use, thanks to their characteristics of configurability.
I/O modules – EX series
Modbus-Tool software for PC
The Modbus-Tool software is an indispensable tool for the configuration and the I/O modules tests. The system of automatic recognition of the module, on a given slave address, allows to have available a ready page to test the specific I/O resources. The tool also has a test mode of the individual codes of the Modbus protocol functions. It requires an RS485 interface on the PC and operates as an RTU master, managing Overdigit modules and any other slave device with Modbus protocol.
Modbus-Tool is a software developed by OVERDIGIT. The full version is activated by using it, at least once, on one of our I/O modules.
Analysis tool for Modbus registers
Modbus-Tool also features a sophisticated analyzer with 32 channels, individually configurable on different addresses of slave and Modbus register, which allows the acquisition and editing of values. The analyzer also has the Plot function to visually track the trend over time of the values of the selected channels. The graph thus obtained can also be saved to a bitmap file. Enabling the Log function, the values of the analyzed registers are also stored in a logging file for later importing the data into an Excel spreadsheet.
