+
+ There is some automatic detection of devices in SEA. You might get a message in NICOS
+ to accept the detected devices. To confirm, execute simply {{frappy()}}
+
+
+ !! Frequently Asked Questions
+
+ ! Are values of sample environment devices automatically stored in the data file?
+
+ When the SE configuration is changed, automatically the following aliases are created,
+ if the corresponding object is available:
+
+ * __T__: the moveable main temperature, change before a scan: {{maw(T, 295)}}, use in a scan: {{scan(T, ...)}}
+ * __Ts__: the sample temperature, potentially readonly
+ * __B__: the magnetic field, moveable
+
+ The aliases above (except T) are automatically put into the envrionment list, and should be saved in the data file.
+ When the sample temperature is controlled, T and Ts point to the same real device.
+
+ You might add additional devices to be stored with the {{AddEnvironment}} command.
+
+
+ ! There is nothing displayed on the SEA client, what is going wrong here?
+
+ It might be that the SEA server is not yet running. Controlling the SEA and Frappy servers:
+ {{{
+ sea start # start the SEA and graph servers
+ sea restart # restart above
+ sea list # show running SEA and Frappy servers
+ sea help # list available sea subcommands
+ }}}
+
+ ! The sample environment device I want to use is not available
+
+ Please use the command {{frappy_list()}} in NICOS to see a list of available configurations.
+ Creating the configuration files for Frappy is still under work. The devices to be used on above mentioned
+ instruments according to the schedule are created first. Please contact [Markus Zolliker], if you want to use
+ a device not yet on the list.
+
+ ! How to Restart a Frappy server(s)
+
+ If a sample environment device is not working properly, for example due to communication
+ problems, it might be helpful to restart the frappy server(s):
+ {{{
+ frappy('restart') # stop and start main and stick frappy servers
+ }}}
+
+ If the problem is related to a device on the stick or addons, you can restart them individually with {{frappy(stick=...)}} or {{frappy(addons=...)}}.
+
+ ! How do I configure to use the sample stick rotation instead of the sample table for omega?
+
+ With vertical field cryomagnets, typically the stick rotation should be used instead of the
+ standard sample table for omega. In this case (configured on TASP, EIGER, CAMEA, ZEBRA and DMC),
+ the frappy_main setups should contain a device __se_om__ for the stick rotation. This is
+ automatically assigned to the device used for omega.
+
+ ||Instrument || name of omega || name of sample table
+ |TASP | a3 | a3_st
+ |EIGER | a3 | a3_raw
+ |ZEBRA | om | om_raw
+ |DMC | a3 | a3s
+ |CAMEA | a3 | som
At line 27 added 3 lines.
+ On horizontal field magnets, the stick rotation is called __om_stickrot__, and is
+ not automatically assigned to omega. In both cases, an alias __dom__ is assigned to
+ either __se_om__ or __se_stickrot__, whatever is present.
At line 28 added 1 line.
+ To change this behaviour, it is possible to assign another device to the alias, e.g.
At line 29 added 1 line.
+ {{om.alias = se_stickrot}}
