This project kicked off with Jakob Sagatowski, the author of the world renowned -renowned All TwinCAT Blog, and leading expert in all things Beckhoff/TwinCAT, in late March/early April. We're very excited to be working with Jakob to advance our PLC workflows, making it easier to achieve a high degree of quality.

We started testing the new TwinCAT BSD operating system for the Beckhoff PLCs. This OS will replace our Windows Compact Embedded 7 PLC image which is standard on all PLCs. Eventually all of our PLCs will migrate to this new OS, and it will be glorious.
TC BSD TCBSD is based on FreeBSD, a derivative of Unix, which makes it very similar to our typical linux operating environment. There are We get many enhancements we get from using TCBSD including:
Given the current focus on cybersecurity we expect to upgrade systems on an as-needed basis to TCBSD. All new projects using PLCs are directed to use the new CX5240 with TCBSD as the OS.

The LCLS-II-HE controlsteam continue continues to advance designs for the various instrument areas. CXI instrument PDR review review was conducted April 19th. FXT, FEE, and XRT Transport , Engineering Peer Review has also been was conducted April 28th. The team is awaiting the committee's report from those two reviews in order to address any recommendation and move forward into the next activity. Common Components EPR is targeted for mid- to late May. The team also finalized the BCR for Lasers with the XES lasers scope changes.
...
The MEC-U team is also looking forward to meeting with various rack vendors such as Rittal and Steven Engineering in May as well as future suppliers (tbd). The rack visits with Rittal and Steven Engineering will consist of an initial visit at SLAC where we will provide them with a tour to see our current rack implementations and discuss the best path forward to improving this for future projects. The second visit will happen onsite at Steven Engineering in South San Francisco where we will be able to play/tinker with their Rittal rack hardware to obtain hands-on experience with their various solutions. They are encouraging SLAC visitors to bring any hardware we wish to test fit or use to spec out their solutions.
NNSA, The National Nuclear Security Administration , are (NNSA) sponsors for an additional project, the Dynamic Material Properties Laser (DMPL) Project, to upgrade MEC-U's long pulse laser capacity. DMPL would add additional long pulse beamlines to the existing HE-LP laser in MEC-U scope, summing to four beamlines at 1.25kJ per beamline , (5kJ total). In April, Controls participated in a cost estimate for this additional scope which will be presented to NNSA in the coming months.

In order to prepare for this, we are collaborating with LLNL and LLE to compile a deliverables list to present to the FAC to sufficiently answer their question. Tangential to this list, Alex is actively working on an overall MEC-U controls architecture diagram so that we can present this to the FAC and to ensure each lab has a clear picture of the path forward. He will also be compiling compile a Software Quality Assurance Plan for MEC-U that will also prove to will be useful in regular ECS development and operations.

The motion control architecture page serves as a guide to use using the standard connectors from the motor all the way to the beckhoff Beckhoff components. The Page page covers all the standard architecture to follow for Stepper stepper motors & and encoders. It also consists of covers architecture for specialized motion and legacy devices. The page is still a work in progress as there are new motors added for different applicationapplications. Any new motor/encoder is first approved by the Motion SME and the ECS-QA team before getting being added to the Motion Architecture page.
...
The DC system architecture page consists of architecture drawings which depicts depicting the connection connections from the supply to the end device which can be a component or a Din-Rail. The page goes over the covers which cables to be used use with which component with the components and links to the released cable drawing page, . A example of the architecture can be shown as below is shown in the image below.

ATEF continues to make steady progress toward becoming a useful tool for guiding and documenting checkouts.
Since the last time ATEF it was featured in the newsletter (Aug/Sept2022), ATEF has received a reworked GUI,
added report generation, and begun implementing active checkout support.
What does this mean?

More details about the trial and how to use GHE will emerge in the coming months. Very exciting!
We're planning to integrate Teamcenter PLM and EPLAN. This integration will bring several advantages, such as improved efficiency by through automatically reflecting changes made in EPLAN to Teamcenter, better part tracking through Teamcenter's BOM, improved lifecycle management with a complete view of history provided by Teamcenter, and enhanced document control through specific repositories and tags.
Furthermore, Teamcenter offers a document control that will check all the blocks (check, revision, approval) and then release the drawing in order to have always a complete ad update version. Moreover, after the release, only an official revision can modify the drawing, ensuring consistency of updates.
The Teamcenter admins will ensure that the integration module is updated with EPLAN to maintain compatibility and optimize system performance.
To properly manage Teamcenter content, several tutorials are accessible with a Teamcenter license. We'll start getting familiar familiarizing ourselves with the software soon.
Several meetings are scheduled to present the last version of Teamcenter to the ECS group and to start integrating Teamcenter and EPLAN.

Some new considerations are being made in the area of UI/UX development. In particular the team is considering new software that allows for quick GUI wire framing wireframing and mock ups. These methods originated in the form of pencil and paper and allow enabled a designer to quickly deploy and demonstrate the flow and appearance of an application. In this way stake holders can stakeholders could quickly identify areas of the GUI that need improvement. That is, what areas of the GUI do they get stuck in and don't know what to do? More broadly, where does the GUI fail to adhere to the common GUI heuristicswere confusing and failed to adhere to common GUI heuristics such as the ones listed here: https://www.nngroup.com/articles/ten-usability-heuristics/.
This pen-and-pencil wire framing wireframing method has made the jump to modern day web application. In recent years, the number of available applications has balloonedthe jump to modern-day web applications. One can find a multitude of available easy-to-use applications with a quick google Google search.
These tools allow not only the enable a designer to create a wire framewireframe, but also allow lets the stake holder to stakeholder join in. Whats What's more, multiple users can edit the GUI wire frame a wireframe at the same time!
Here's an example of a Figma session with a quick mock up for the Compound Refractive Lens.
