Class Description


A device can be integrated in Tango control system by developing a specific Tango device server software for the device. In situations when the Tango device server software is not available for the device, but software support for the EPICS control system is available instead, it is possible to use the Tango2Epics Tango device server to expose the device in Tango system. It serves as a bridge, in form of a Tango device, to EPICS control system. PVaccess device exposes the existing EPICS Process Variables (PVs) of the device in form of Tango device attributes, states, and emulates a preconfigured set of Tango device commands by using the appropriate EPICS PVs. By using the Tango2Epics Tango device, integration can be achieved through configuration only, with no development required. More information can be found in the user manual, located: http://sourceforge.net/p/tango-ds/code/HEAD/tree/DeviceClasses/Communication/Tango2Epics/trunk/doc/Tango2EpicsGateway.pdf.

Commands:

Name Description
ResetInput: DevVoid
Output: DevVoid
Allegedly represents a command for reseting the device. It changes the values of specified PVs to the specified value. Specifications about these actions are read from the Variable device property. See the user manual for details on configuration.
OffInput: DevVoid
Output: DevVoid
Allegedly represents a command for turning the device off. It changes the values of specified PVs to the specified value. Specifications about these actions are read from the Variable device property. See the user manual for details on configuration.
OnInput: DevVoid
Output: DevVoid
Allegedly represents a command for turning the device on. It changes the values of specified PVs to the specified value. Specifications about these actions are read from the Variable device property. See the user manual for details on configuration.
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.

Pipes:

Properties:

Name Description
SubscriptionCycleDevDouble This property specifies the value of the time period for subscription cycles. Note: when closing the application, it might take one subscription cycle period of time to close the subscriptions.
ArrayAccessTimeoutDevDouble This property specifies the value of the preferred timeout (in seconds) for when trying to access a array PV.
ScalarAccessTimeoutDevDouble This property specifies the value of the preferred timeout (in seconds) for when trying to access a scalar PV.
VariablesArray of DevString This is the property, that defines which PVs will be linked to what Tango attributes, commands or states. It consists of multiple items, each specifying one PV and its properties. Additionally it provides the configuration for linking the PV to the Tango attributes, commands or states. See the Extended BNF Format of device properties in the user manual for the format of this property and its items.

README

Tango2Epics gateway is a Tango device server used for the integration of the devices with EPICS support in Tango control system.
By using the Tango2Epics gateway, integration can be achieved through software configuration; no development is needed.

Please refer to the Tango2Epics Gateway User's Manual (doc/Tango2EpicsGateway.pdf) for the instructions on how to build and use this device server.

Tango2Epics Gateway package is organized in the following directories:

src/ .... source code
configuration/ .... gateway configuration file and database import script
demo/ .... EPICS IOC simulator and client test script
doc/ .... User's manual and html documentation
