IMAT: WPI Syringe Pump IOC & OPI

[kjwoodsISIS]

As an IMAT scientist, I need a driver so that I can use a WPI SP2XX Syringe Pump in my experiment.

Acceptance Criteria

1. Solution to be ready for 26th June.
2. Other acceptance criteria - TBD (depending on chosen solution)

Notes

1. Scientist requesting this work is Genoveva Burca.
2. LabVIEW VI for WPI SP2XX Syringe Pump already exists:
   1. Front Panel VI: C:\LabVIEW Modules\Drivers\WPI SP2XX Pumps\WPI SP2XX Pump - System.llb\WPI SP2XX Pump - System - Front Panel.vi
   2. Setup Dialog: C:\LabVIEW Modules\Drivers\WPI SP2XX Pumps\WPI SP2XX Pump - System.llb\WPI SP2XX Pump - System - Setup Dialog.vi
   3. Documentation: C:\LabVIEW Modules\Drivers\WPI SP2XX Pumps\Documentation
3. The work to be done for this ticket is as follows:
   1. Determine if support for WPI SP2XX Syringe Pump can be implemented via lvDCOM.
      1. If so, do it (create appropriate XML file, front-panel OPI & setup dialog OPI)
      2. If not, proceed to steps ii - iv.
   2. Examine existing VIs to discover which sub-set of commands are supported.
   3. Implement these as an IOC
   4. Create OPIs corresponding to the Front Panel & Setup Dialog.
4. For reference: WPI SP2xx Syringe Pump.
5. It would be worth discussing the functionality required with Gareth and/or the scientist .

Whoever picks this up: please estimate the number of story points.

WPI SP2XX Syringe Pump hardware now in office. Connected to MOXA - port 8. Device is talking so the cabling is correct. Documentation forwarded.

For anybody developing this device driver and uses LabVIEW as a reference, please ensure they are using the latest version from SourceSafe. It was modified recently.

Added the following features to the IOC:

• run: starts the device
• stop: stops the device
• dia: sets the diameter
• dia?: gets the present diameter settings
• run?: gets the current run status
• mode: sets the mode of the device
• mode?: gets the mode of the device
• dir?: gets the direction of the device
• dir rev: reverses the direction of the device.
• error?: queries for the error
• Also added mismatch for errors raised using "\r\nE".
• Added PV to check when NA is returned as a prompt when setting run, stop, dir rev or dia.

Note: the tests use parameterized 0.6.1. Please install this package to run the tests correctly.

Commands left to do (from the manual) looks like:

• del?
• ratei
• ratei?
• ratew?
• ratew
• voli
• volw
• voli?
• rev

Also tested #3275 as part of this. Issues I found were mostly just tidying up. In the interest of speed I will merge this and further issues are in #3287. Note that I could not get the device to produce any errors so had to rely on IOCTests for error cases.
