Delta Tau Power PMAC EPICS Device Support Manual

8 February 2013

3 Introduction

The Power PMAC EPICS software module contains a low level SSH driver, asyn

driver and device support code for the Delta Tau Power PMAC motion controller.

The software has been written to closely match the already existing PMAC EPICS

support code where possible and to provide the standard motor record interface as

used by many installations.

A small test application is present within the module that can be used to communicate

with the Power PMAC from a terminal shell, and can be used to verify the SSH driver

is functional and that the Power PMAC is responding as expected. The module also

contains a test application with EPICS database files and startup scripts to quickly get

started with a test EPICS IOC. There are some EDM screens that can be used to

interact with the motor records and a very simple set of CSS BOY files to provide a

basic interface using CSS.

4 Requirements

This section details the hardware and software requirements for using the Power

PMAC EPICS device support code.

4.1 Hardware Requirements

The following hardware is required to run the device support code:

- Standard PC with an ethernet port.

- Power PMAC present on the network. For operation with the EPICS device

support code the Power PMAC should be configured to have a static IP

address and this address must be specified in the start-up script.

4.2 Software Requirements

The following software must be installed to run the driver and device support code:

- Linux operating system. The device support code has been written using

general asyn, motor and EPICS base function calls and methods and as a result

will be fully functional on any system that can compile the required versions

of EPICS base and the asynDriver and motor modules. The device support

code was developed on Debian 6 (32 bit) but has also been tested on CentOS

5.7 (32 bit) and CentOS 6.3 (32 bit and 64 bit).

- EPICS Base (version 3.14.12 or later)

- EPICS module ‘AsynDriver’ (version 4.17 or later)

- EPICS module ‘motor’ (version 6.7.1 or later).

- MSI extension for EPICS (version 5 or later). Required if building the

supplied test application

- EDM to run engineering screens, if they are required.

- CSS BOY to run the opi screens, if they are required.

- libssh2 library (not an EPICS module, see installation instructions below).
