P51 is an embedded CPU, based on AMD Am186CU microprocessor at 48 MHz, especially designed by Leomatic for its real-time control systems based on SYSTEM5 modules.

It acts like a PLC and a CNC together, so allowing the complete control over an automatic machine or line.

On board resources: RAM, FLASH memory, 2 serial and 2 USB ports.
These communication ports, configurable and versatile, make P51 an ideal front-end for connections with external devices, such as host PC and/or User's Panels.

P51 may be connected to the other SYSTEM5 modules by mean of a parallel bus (local) or in a CANBus network architecture (remote).
Local connections need a low-cost 20 pins flat-cable (very compact);
remote connections need a simple twisted pair (very reduced wiring).

The control logic (PLC) is totally user-programmable; it has instructions to handle any resource (hardware and firmware internal variables) of the connected SYSTEM5 modules, included commands for motor-axes.

Leomatic supplies P51 modules with a free-of-charge software suite, including technical manuals, which allows a quick and easy development of a custom software for a Windows PC.
A programmer may use the
procedures/methods of the Dll, or directly include some of the ActiveX supplied; he may so handle all of hardware resources and/or realize a software user's interface for the specific application.

The software suite also includes the following utilities:
- Automation Builder: a PLC programmer to edit/compile/download a PLC control  logic;
- PncTool: a supervising tool to configure/inspect/test the whole PNC
               system or any of its modules.

    Embedded multi-tasking scheduler with the following tasks:

  PLC: executes a logic PLC, totally user-programmable on a standard PC and the SW utility Automation Builder

     CNC: work-cycles in ISO language, allowing interpolations up to 6 motor-axes together.

     Data and parameters storing: machine data, user data, recipes, electronic cams, work-cycles, ...

     Data exchange with the other SYSTEM5 modules and with external devices (host PC and/or User's Panel), by mean of selectable protocols: LEOMATIC BPMU or XFer, MODBUS RTU, MEWTOCOL, user definable under PLC control, ...

     Machine status monitoring.

  Test and diagnostic functions, also in run-time, for on-field technical assistance with a standard PC and the SW utility PncTool

     The on-board firmware, stored on Flash memory, may be changed  (downloaded) also on-field through a standard PC and the SW utility PncTool

     In case of malfunctions, you may activate a special boot firmware, stored on a protected page of flash memory.
It grants a recovery startup: some functions are reduced but the Leomatic protocol on
third CANBus port is fully operative, so you can run the software tool in order to download the on-board firmware or to test the card itself.

     P51 CPU, once configured, at each start-up will send automatically all application data to the other SYSTEM5 modules.
This feature allows a very easy replacement of a damaged module, because it doesn't need any preliminary configuration but the setting of the on-board dip-switches (they must be the same as the replaced module).

     It is possible to ask Leomatic for a customized Firmware version, even if a new communication protocol is needed.


Technical characteristics


      AMD186CU microprocessor at 48 MHz

      On-board memory:

      512 kbyte of volatile   RAM

      512 kbyte of retentive RAM

       2  Mbyte of FLASH  (to store the on-board firmware
                              and application data)

    Parallel bus (10 MByte/s) for high-speed local connection to other SYSTEM5 modules with the same bus (P53S, P58S, P57S)

    2 serial ports, each configurable as RS232,RS422,RS485 or CANBus for connections to other SYSTEM5 modules or to external devices (host PC and/or User's Panel).
The signals of different electrical level are carried out on different clips/pins.

    2 USB ports for connections to: host PC, User's Panel, service PC.

    P51 may be connected to other SYSTEM5 modules by mean of a parallel bus (local) or in a CANBus network architecture (remote).

    It's possible to realize multi-CPU systems (up to 32 P51 modules on a same network, under one only host device).



    Power requirements:
+24 Vdc nominal (min. +15 Vdc, max. +30 Vdc)
95 mA on +24 Vdc



    The module is ready to mount on a standard DIN guide.

    Dimensions: 101 × 120 × 17,5 mm

    Front panel is a transparent, elevating cover, so allowing the view of on-board leds and the access to the configuration dip-switches.

    6 leds to monitor module status and communication activities.

    Removable clips, screw type, for communication ports and power supply.
