REFL_WFS and REFLS_WFS_F3 Picomotor remote connection

Hirose-san, Ikeda

REFL_WFS:
Changed network from DGS to Pico network.
After the change, it was confirmed that the motor works from medm.

The network switch on top of the IOO rack was removed because of the network change.

The connector on the computer room side was also removed because it was connected to the LAN "N1 40 SW P2 IOO SW IN".
Probably the SW on the computer room side is now not connected to anything.

REFL_WFS_F3:
New connection to the Pico network and confirmed that the motor works from the medm.

The WFS1,2 PZTs are now placed on a shelf inside the optics table cover. It will be placed on top of the optics table cover soon afterwards, as the temperature in the optics table may rise and become noisy. We will do the initial alignment as they are reconnected, so we will check the operation of the picos for WFS1,2 on the digital system there.

There is mirrors for PZT on the way to the incident QPD3,4 of REFLWFSf3. That mirrors is not connected to the PZT driver. After connecting and the initial alignment to the QPD, I will check if the picos for WFS3,4 moves the beam position of the QPD on the digital system.
