Usage

The usage is the same than the Eurotherm 2000.

In the Bliss session import the Loop object (ex: eurohp_loop) and type the name in the bliss shell to print informations.

Access the associated input and output with eurohp_loop.input and eurohp_loop.output.

Ramp to a given setpoint temperature with eurohp_loop.setpoint = 23.

Change the ramp rate with eurohp_loop.ramprate = 10.

If ramprate is set to zero (eurohp_loop.ramprate = 0), the controller will reach the setpoint temperature as fast as possible.

Get current input temperature with eurohp_loop.input.read().

Perform a scan with the regulation loop as an axis with eurohp_loop.axis.

Access the controller with eurohp_loop.controller and all expert commands with eurohp_loop.controller.cmds.

All current values of the controller parameters can be retrieved with eurohp_loop.controller.dump_all_cmds.

Status Information

In a Bliss session, type the name of the loop to show information about the Loop, its controller and associated input and output.

Use eurohp_loop.controller.status or eurohp_loop.controller.state to retrieve information about the controller.
