This talk describes how to use an EPICS “soft IOC" to control and monitor an Allen-Bradley PLC-5 through a TCP/IP link. I will explain how we converted twenty accelerator process water station PLC'S from a slow obsolete serial copper wire system to a fast network TCP/IP interface.

Network Variables are a convenient method for sharing information between National Instruments (NI) software and hardware. We have developed a configurable EPICS IOC for accessing information from such sources and exporting them as process variables, the intention being to use the shared variables as a clean interface between our EPICS control system and some specific third party provided equipmen ...

To keep the data obtained at the user stations synchronously with the machine data we have added to the time stamp at a particular EPICS waveform record (pyroArray) a laser-shot-number. Unfortunately we are still not sure how to handle this timestamp very sensible. Therefore, I would like to encourage a general discussion on the timing and how the time stamp should be used.

A controls centric status update concerning the various systems, the R&D and the project plans for the Multi-bend acromat (MBA) upgrade planned for the Argonne photon source. The MBA upgrade will rebuild the current third generation light source storage ring with a new lattice which, among other things will dramatically increase x-ray brightness, will reduce the electron beam emittance from the pr ...

Recent card-size PCs, such as Raspberry Pi or BBB (Beagle bone black), have enough performance to use as EPICS IOCs. In ERL in KEK-Tsukuba, a few pieces of BBB IOCs with serial lines were developed to monitor radiation-monitoring instruments . However, due to lack of long-term reliability and hardness, mass introduction to accelerator controls is not realistic. We have started stu ... More

Driver/Device Support sis3316/ip We have developed a driver support for the digitizer Struck sis3316 which uses the Gbit-Ethernet interface on that card. To communicate with the digitizer we are using a C-library supported by Struck. The communication is based on the UDP protocol. Within the library unfortunately error cases are not threaded properly. We had to customize the library in some pla ... More

Additional information from the logger in CS-Studio would make it easier to identify and resolve issues. It is not possible to have the logger's default configuration set to a very fine level due to the volume of messages it would produce. The logging configuration tool provides a user interface which lists all the JVM loggers and allows users to dynamically change their logging levels. This allow ... More

Progress of developments for EPICS Base undertaken at NSLS2 with the goal of improving the performance and scalability of the process database on modern hardware. Much work has also been done to expand unit test coverage in Base in an effort to maintain release quality.

In this paper we present the generic solution for testing PCI-based hardware devices on Linux. For simple device manipulation, EPICS provides additional layer of complexity, which is usually not desired by the people who are just interested that device works on its own. The paper presents four software modules that were developed to ease the testing of such hardware devices remotely, without the u ... More

The OWI Edge Robotic Arm is a child's toy that is built from a kit. An optional USB interface is available through which communication from a Linux computer is possible. Using the Raspberry Pi and asyn support, this hands-on IOC demonstrates how modestly a "complete" control system might be constructed, including GUI.

Session: Five Minute Talks
Hour Log manages information about current experiment, source, vault, beams, breakdowns, and shifts at NSCL. Operational staff use it to record notes and the corresponding facility status. It generates usage and breakdown reports for the funding agencies. It interfaces with Olog, Archiver Appliance, Training, and Trouble Record systems. It provides a RESTful API which is used to display curren ... More

Even after alarms have been addressed, maintaining the alarm history is useful to detect noisy alarms, find correlations, etc. We are using ElasticSearch, Lucene, and Kibana (ELK) along with Apache Camel to archive alarm messages and provide tools to query and visualize them.

We will present the NSLS-II fast orbit feedback system commissioning results. It includes the system architecture, the system characteristics measurement and system performance. In the system architecture section, we will describe the overall hardware architecture of the system and the communication between hardware. In the system characteristics section, we will present the measurement in real sp ... More

A review of how the EPICS tools are used to provide remote access to the LIGO interferometers. This will include discussion of the current tools being used, the customizations that we have made, and the effort to easily package and distribute the tools to a distributed user base.

The pvWebMonitor package provides a background service that monitors EPICS PVs and writes them into customized HTML files in a WWW server directory. The service can be started and stopped by a manage.csh script for automated startup in a cron task or at system startup.
