Interface for an actuator controller¶
It can be applied for any type of hardware, which requires a two state action (set_in/set_out) and might couple the action with a test of achievement.
Warning
The underlying controller should at least have a method .set() and if possible a method .get().
Example YAML configuration file¶
class: actuator name: detector_cover controller: $wcid29a actuator_cmd: detcover actuator_state_in: detcover_in actuator_state_out: detcover_out actuator_inout: {"in":0, "out":1}
The controller is Wago. The predefined tags correspond to:
- actuator_cmd: the name of the control channel
- actuator_state_in and/or actuator_state_out: names of channels, commected to the limit switches
- actuator_inout: values to set 0 or 1
class: actuator name: capillary controller: $diffractometer actuator_cmd: CapillaryPosition actuator_state_in: CapillaryPosition actuator_state_out: CapillaryPosition actuator_inout: {"in": "ON", "out": "OFF"}
The controller is MD2S. The predefined tags correspond to:
- actuator_cmd: command to set the actuator
- actuator_state_in and actuator_state_out: commands to read the status
- actuator_inout: values to set ON and OFF
