The Web PLCs, WP240 series, are extremely compact devices with unique features for a PLC. In fact, in addition to performing the automation control functions, typical of a PLC, this device can also be programmed to interact with the outside world via the Web. The libraries, included in the CoDeSys programming tools, allow numerous TCP/IP networking features with which the PLC can exchange information with any other system on the Internet.

Web PLCs – WP240 series

The CoDeSys programming tool, included in the price, allows the PLC application development using IEC61131-3 standard language and the creation of graphical pages viewable by the web server.
The I/O expansion can be done via RS485 and CAN serial ports. The interfaces are isolated and can be used with communication speeds up to 1Mbit/s.
To connect the I/O modules it is available the Modbus protocol (master/slave) and the CANopen protocol (master/device). In addition on TCP/IP network it can also be used Modbus protocol (client and server).
The Web PLC is equipped with an internal hard disk (8MB) to which can be added two disks (SD card and USB memory). All disks can store the PLC program, the HMI graphic pages and any of the application data files.
Real Time Clock
The Web PLC is equipped with an internal clock with back-up system in case of power failure. The clock can also be synchronized to an atomic time server thanks to the NTP client function.
TCP/IP communication
The Ethernet port is used for the CoDeSys programming and for the application communication over TCP/IP network. Library function blocks, with various client and server capabilities, are available.
Web visualization
The graphic pages developed within the CoDeSys programming tool are a powerful HMI graphic interface of the application. The pages are made accessible on the local network or the Internet by the web server integrated in the PLC.
FTP and Telnet
The Web PLC includes an FTP server and a Telnet server for the management of files and the device. Both the application program that the data files, configuration and logging are accessible safely on LAN network and Internet.
Radio modem
The Web PLC is available with built-in options such as the second serial port (RS485/RS232) and the UMTS or GSM radio modem. The versions with radio modem allow the data connection on the Internet and the handling of SMS and number calls.
The PLC Web modules are compact in size and require only 22.5mm of DIN rail.

The Web PLCs of WP240 series are DIN rail modular product with PLC and gateway functions for the complete management of automation and remote control with Ethernet connectivity.

Programmable with CoDeSys environment, the most widely used IEC61131-3 development system, available at no additional cost. Graphic and textual languages for quick creation of applications.

Optoisolated and fast (1Mb/s) CAN interface with CANopen master/device protocol for the connection to the I/O devices and the control of systems with this communication standard. Optoisolated RS485 interface with libraries for direct access to the port and Modbus master/slave protocol.

Easy and direct integration of I/O modules inside CoDeSys tool with Modbus extensions for the complete update at 1Mb/s in a single frames exchange.

Included libraries for TCP/IP protocols as Modbus TCP/IP (client and server), SMTP for E-mail sending with attachment, HTTP client with SSL, FTP client, DNS client, NTP client.

Integrated Web Server for viewing via LAN and Internet of the HMI pages created by CoDeSys with graphic objects that can interact with all program variables.

FTP Server for managing and updating the files of operating system, application and data/parameters. Two storage units (SD card and USB key) can be added to the internal disk allowing GBytes of memory available for storage and data logging.

Real Time Clock with automatic daylight saving time and NTP client function for time synchronization with the atomic clock.

Internal connector for the expansion of functionalities and interfaces. Available versions with the second RS485/RS232 port and the GSM/UMTS radio modem for the permanent connection to the Internet, the access to portals, SMS sending/receiving functions and phone calls handling.
