The LP30 and the LP31, which are ARM-based panel PACs (Programmable Automation Controllers) by Asem (Italy), combine visualization, control and remote assistance functions. The LP31 features a CAN interface and CANopen.
THE PANEL PAC FAMILY IS CHARACTERIZED by its range of sizes. The 16-million colors LED backlight TFT LCDs are available with aluminum or aluminum true flat front panels with IP66K. They are available as 5,7 inch, 8,4 inch, 10,4 inch, 12,1 inch, and 15 inch LCD sizes in 4/3 aspect ratio and with 7 inch and 15,6 inch LCD sizes in 16/9 aspect ratio. Both PAC families can manage Ethercat, Modbus TCP/IP, Modbus RTU (serial), while the LP31 can also manage CANopen master fieldbuses to control automation I/Os and devices. On Windows Embedded Compact 7 Pro, they integrate the features of PHMI4 visualization software in Basic or Advanced versions, Codesys SoftPLC 3.5, and Asem Ubiquity.
The LP31 systems feature an isolated power supply with galvanic isolation to prevent common mode noise at low and medium frequencies on the power supply line, as well as ground loop noise, extra-voltage caused by lightning and for power supply with a grounded positive terminal. They have FlexCAN integrated controller, one optoisolated channel (500 V), and one DB9M connector.
The systems are based on a motherboard with an ARM Cortex A8 1 GHz/800 MHz processor (Freescale i.MX535 or Freescale i.MX537) and the Asem Smart Memory System, with 512 MiB system RAM (DDR3-800), 256 MiB Nand-Flash, write-protected, for the operating system and runtime of PHMI4 and Codesys SoftPLC, a 2 GiB eMMC memory for management and storage of HMI project data and a slot for a removable SDHC memory card. The motherboard also has an RS-232/422/485 configurable serial port with MPI support, two USB 2.0 interfaces and two Ethernet interfaces. The systems also have external-access SD slots.
