A E4C diffractometer server is introduced to Online by the following entry on /online_dir/online.xml:
</hw> ... other devices <device> <name>dffrctmtr</name> <type>diffractometer</type> <module>e4c</module> <device>p09/e4c/diffrac</device> <control>tango</control> <hostname>haso107tk:10000</hostname> </device> </hw>
For E6C diffractometer server we need:
</hw> ... other devices <device> <name>dffrctmtr</name> <type>diffractometer</type> <module>e6c</module> <device>p09/e6c/diffrac</device> <control>tango</control> <hostname>haso107tk:10000</hostname> </device> </hw>
Note that the device name dffrctmtr is fixed.
Note also that E6C has two subtypes. They are distinguished by the property DiffractometerType which can have the values E6C or PETRA3 P09 EH2.
Details about settting up a diffractometer server and using it can be found in the “online -tki” manual.
