TD-240 PLC Touch screen Description

TD240 is a 320x240 pixel touch-screen with a 3.5" and 256 colours TFT display. This device integrates the range of Operator panels besides TD320 model. It has programmable PLC characteristics, the same Ladder language of DIN rail mounted PLCs and the graphics is programmable by TdDesigner, the same “drag and drop” development environment of TD320 terminal.
It enables to set and visualize data, images, help messages, flashing texts, as well as the alarms management on historical buffer and profiles storage for process/set-point variables. Through development environment PLProg (the same of Pixsys PLCs), it is possible to integrate the logic into the terminal.
It can be ordered with two different configurations, the first one (TD240-AD) can be used only for graphics and interface through serial output MODBUS with external modules of analogical and digital I/O by two serial port RS232/485 Modbus RTU protocol or free-port. The second one (TD240-11AD) integrates in the same product both visualization and the complete hardware interface with 4 universal analog inputs, 16 programmable digital I/O and 4 analog output. Memory-cards are available for the up-load of firmware.
Total memory is 512KByte, both firmware and programming memory flash (128KByte + 384KByte user memory for ladder and graphic programming). EEProm memory to store user data (2KByte EEProm area + 60KByte Memory area). RAM 2KByte with back-up battery. A memory card is available for program upgrade and/or data storage.
