Combining PLC and HMI gives users the opportunity to operate on a minimum of budget, programming time and wiring. The units can support up to 256 I/O, as well as 24 auto-tuned PID loops to control temperature, level, and pressure. The graphic LCD, 2.4-inch 128 x 64 pixel operator interface supports more than 1024 user-designed screens with 400 images per application and a 20 key keypad, and can display trend graphs and a text string library. Internal memory holds 512K of application logic, plus 128K for fonts and 256K for images. Communication options include Ethernet, cellular, and industrial protocols such as MODBUS, DF1 slave, J1939, CANopen and more. In addition, the units can be 'taught' to communicate via almost any ASCII protocol. The controller is also capable of time based and immediate interrupts, making it a suitable for rapid response applications such as packaging machines.
