Test the database scheme

1. Test PVSS can control the HV sources

2. Load HV channel data from ASCII file

3. Test connection to Configuration DB

HV and LED control signal distribution board

• Outputs– 200 outputs for the CW base

control voltage distribution in range from 0 to 5 V with 12 bit precision.

– 16 outputs for the LED intensity control signal distribution in range from 0 V to +5 V with 12 bit precision.

– 8 outputs of the stabilized LV and +100 V power supplies for feeding the 8 groups of the CW base.

• Inputs– SPECS bus for

interconnection with ECS.– Power lines from external

power supplies.


PVSS Control of the HV signal distribution board

• At present the board is successfully controlled by a PVSS program interfacing the SPECS bus– HV DAC values can be correctly set and

retrieved.

• Using an automated script

• Through an operator panel

• Importing data from an ASCII file



Board description using FwHw tool



Sample Operator Panel



Importing data from an ASCII file (tab separated)


HV board Control – work in progress

• Connection to the Configuration Database– New tools shall be released by the online

group.

• Inserting the HV control board into the ECS control hierarchy– Defining the Device Unit associated to the

board by the fwFSM tool.

• Designing definitive operator panels and refining scripts and file formats.
