Python with Twisted package and
pyCFClient(
https://github.com/ChannelFinder/pyCFClient
)
twistd -n recceiver -f cf.conf
•
UDP broadcast to port 5049, with TCP callback info
•
Receive PV from IOC/RecCaster at the TCP port
•
Forward PV with pyCFClient API to ChannelFinder Web Service
•
Configuration:
•
cf.conf
•
addrlist = 255.255.255.255:5049
•
infotags = test hello
•
alias = on
•

SpringBoot/Tomcat
•
Receive PV from RecCeiver via HTTP REST API
•
Use ElasticSearch Index DB
•
Three indices:
mapping_definitions.sh
•
channelfinder/cf_channel
•
properties/cf_property
•
tags/cf_tag
•
Use embedded LDAP for authentication, configured in cf.ldif
•
Configuration:
app.properties
; cf.ldif
•
server.http.port=8088
•
logging.file=${java.io.tmpdir}/channelfinder.log•
elasticsearch.network.host: centry.fnal.gov
•
elasticsearch.http.port: 9200
•
Run
nohup java --add-exports=java.naming/com.sun.jndi.ldap=ALL-UNNAMED
-Dspring.config.location=file:./target/classes/app.properties
-jar target/ChannelFinder-4.0.0.jar > /dev/null 2>&1 &

Includes setup and deployment diagrams for ChannelFinder on vclx4, along with details about RecSync components for EPICS module communication. Also covers RecCaster configuration and registration of support components. The documentation further discusses RecReceiver setup, Python integration with Twisted package, and usage of PyCFClient for communication. The information extends to ChannelFinder Web Service configuration, HTTP REST API usage, and deployment details for ChannelFinderService. Lastly, it touches upon Phoebus display builder and web runtime for Java-based GUI interface development.
