Overview
The XL4 programmable logic controller is in the same ¼ DIN form factor as our extremely popular XLE and XLT. XL4 has a full-colour LCD TFT Display with QVGA resolution. XL4 comes fully equipped with 100Mbps Ethernet built into every model. No additional Ethernet add-ons or accessories are needed. The XL4 Ethernet support includes an integrated Web Server, FTP Host, Email, Modbus/TCP Master/Slave, Programming and more.
The XL4 includes both a USB Host port and a USB On-the-go Port – each at USB 2.0 speeds (480Mbps). The Host Port allows the connection of removable FLASH drives, supporting drives up to 2TB. The On-the-go Port provides the fastest communications interface for Programme Change on Line (Online Change). XL4 I/O expansion is not limited to its Built-in I/O.
