Device Driver/device support modules and Interfaces

    EPICS DIM interface

    The basic idea of this device support module for EPICS is to provide an interface to the DIM protocol in order to read/write EPICS data seen from the DIM world and to act from EPICS as client/server for services and commands in the DIM regime.

      DABC extension to the EPICS DIM interface

      Based upon the existing EPICS DIM interface several data structures provided by DABC (Data Acquisition Backbone Core) transporting values together with additional attributes, similar to EPICS records, via the transport mechanisms of DIM should be able to be accessed from EPICS via an extension to the above mentioned original interface.

    HADCon(trol) / TRB based controls

    The HADCon(trol) general purpose board provides access to many external interfaces and devices. This section is about interconnecting those with the EPICS technology.
      Temperature measurement HADCon(trol)

      The HADControl general purpose board provides access to many external interfaces and devices.
      The task is to replace the already running ansatz of the HADES MDC Gas Monitor temperature measurement by a pure EPICS based design.

      CANbus implementation on HADCon(trol) and control via access

      The objective of this project is the implementation of a software on the HADCon(trol) board's AVR micro controller. This software enables the control of AVR micro controller's CANbus Interface using an (ASCII based) Application Programming Interface (API). Integrated via streamDevice driver into EPICS the control of CANbus devices will be possible within EPICS.

      Multi-purpose control implementation on HADCon(trol) for HADES

      edit

      HadCon is a general purpose IO module for detector and experiment control as well as for small data acquisition systems.

      hadcon

      (HADControl general purpose board) Since its first application has been a power monitor for the Hades Shower Detector it has been formerly introduced and well known as HadShoPoMo (Hades Shower Power Monitor (HADControl/HadShoPoMo general purpose board).

      HadCon has an SoC on-board, ETRAX 100LX MCM 4+16 from AXIS (Wikipedia: en/de) - which will be discontinued, see the new HadCon2.

      Running a standard Linux the Etrax provides "Connectivity to the world" via TCP/IP.
      On the other side it connects via its internal serial interface to an ATMEL AT90CAN128 microcontroller and optionally to an Xilinx CPLD.
      Via this junction the ATMEL provides a multitude of possible connections to field buses and general I/O ports.

      EPICS base and its applications, modules, and extensions can be cross-compiled to run on Etrax Axis' CRIS architecture (see section Architecture: ETRAX's CRIS by AXIS

      • Summarizing:
        • CPU: AXIS ETRAX 100LX MCM 4+16
        • Microcontroller: ATMEL AT90CAN128
          • I2C (internal)
            • 2 × 4-channel 8-Bit DAC - Digital-to-Analog Converter
          • CANbus
            • galvanically isolated CAN - High-speed CAN Transceiver
              • optional external power supply
          • SPI
          • ADCs
          • RS232
          • 32 digital I/Os
        • CPLD: Xilinx XCR3064XL-6CS48C
        • 2 × Rotary Code Switches, hexadecimal coding
        • Ericsson PME 5218TS switching regulator for up to 6A 3.3V power usable for other boards
        • full EPICS support

      This projects' objective is to combine all existing HadCon (HADControl general purpose board) implementations into one μController code for its ATMEL AT90CAN128:
      • CANbus (based on the thesis and work of L.Fouedjou, see Project Page)
      • One-Wire bus implementation
        • ADC
        • DAC
        • Temperature
        • Switches
      • HadCon's internals
        • DACs
        • ADCs

      Multi-purpose control implementation on HADCon(trol) 2 for HADES

      HadCon2 is a credit-card sized general purpose I/O module for detector and experiment controls as well as for small data acquisition systems.

      hadcon2

      It is the successor of the discontinued first version HadCon ( HADControl/HadShoPoMo general purpose board, HadCon @ Epics Wiki).

      The module has an ATMEL AT90CAN128 microcontroller providing a multitude of connectivity:
      I2C (8/4 fold (intern/extern) multiplexer), 6 channel 1-wire master, 8-channel 8bit DAC, galvanically isolated CAN - high-speed transceiver, 8-channel 10-bit SAR ADC, byte-oriented SPI, in total up-to 53 programmable I/O lines and optionally a Lattice MachX02 FPGA for fast data processing tasks.

      While the discontinued precursor HadCon had an SoC on-board, its successor HadCon2 has broken up this concept in favour of a more open access:
      It doesn't have any CPU on board, but a USB connector to directly allow communication with any type and size of computer (e.g. PC, raspberry PI, dreamplug, ...) having an USB port on one side and at the other end the microcontroller and the FGPA. This communication is based on an ASCII-based protocol in view of easy implementation in detector control systems like e.g. EPICS and LabVIEW.

      • Summarizing:
        • Microcontroller: ATMEL AT90CAN128
          • I2C
          • CANbus
          • SPI
          • ADCs
          • ...
        • FPGA: Lattice MachX02-1200-HC
        • FTDI USB to serial UART interface
          • USB 2.0 connector
          • Power over USB
        • I2C devices
          • 6 × Single-Channel 1-Wire Master
          • 1 × 8-channel I2C-bus multiplexer with reset
          • 2 × 4-channel 8-Bit DAC - Digital-to-Analog Converter
        • galvanically isolated CAN - High-speed CAN Transceiver
          • optional external power supply
        • 2 × Rotary Code Switches, hexadecimal coding
        • Reset Button for ATMEL
        • 11 × LED's, free programmable

      This project's objective is to adopt the project specification made for the Multi-purpose control implementation on HadCon to the new but very similar hardware of HadCon2. This includes the access to the different devices via an ASCII based protocol. This provides:

      • ATMEL's internal
        • ADC, SPI, CANbus, I2C, Registers
      • Communication with MachX02
      • I2C
        • 1-Wire bus implementation via I2C
          to access 1-wire sensors and actuators:
          • ADCs
          • Temperature sensors
          • Switches
        • DACs
      • Relay applications

    PLC Industrial Control devices

    In this section several industrial control devices running PLC or SPS programs are addressed
      SattCon 200, ABB, HADES cryo control

        There is a request of HADES to be able to integrate readings from the control system of their cryo system control into the EPICS control system of HADES Maybe, in a second step, also changing of values is of interest.
        Right now the system runs a PLC on an ABB SattCon 200 system, which can be accessed by a Windows based control PC, via the ABB Automation PC-based programming tool DOX 10.

      Beckhoff Device Access via EPICS ModBus
      - CBM RICH test mirror positioning system
      - Summer Student Project 2011

        As part of the summer student program 2011 at GSI this projects objective is to develop, evaluate an exemplary motor control, on basis of basic existing components which will
        • use Beckhoff devices
        • be accessed via modBus
        • be controlled via EPICS
        • be displayed, e.g. with CSS
        • (offered to be) used for TASCA, CBM, HADES

        UPDATE
        Meanwhile the project became more detailed, since CBM showed interest to have a RICH mirror setup motor controlled. This setup requires to have 2 servo motors with a gear reduction to tilt a gimbal mounted planar mirror element (400 mm × 400 mm) in 2 directions. It is foreseen to use this setup during CBM's next test beam time.
        TASCA
        Until the ordered parts have arrived, we could use spare equipment of TASCA to develop and test. Thank you.
