P41: Am186CU CPU

Integrated communication peripherals
IPC bus

  • Embedded CPU, based on the AMD Am186CU microprocessor, RAM, FLASH memory, two serial ports for connection to external devices, one USB port.
  • Designed to manage Leomatic Rack PNC systems.
  • It manages Leomatic cards for Bus IPC and integrates the functions of a PLC and a CNC, thus allowing the complete control of automatic machines.
  • By connecting a service PC to a serial port, it is possible to download the executable firmware from the board (guaranteeing developers maximum flexibility in the use of the microcontroller and its functions), the firmware of the other cards Leomatic present in the PNC RackThe PNC system can be configured for specific applications and/or system status can be monitored.

Leomatic provides a software environment, complete with user manuals, that allows you to manage the interface between a PC and the P41 CPU board. To manage the PLC functionality, a PLC programmer (LeoPlc or LAB utilities) is available.
