[Dave B, Timesh M]
While the IFO was recovering from an earthquake, we took the opportunity to go to the X end and connect the NCAL Beckhoff PC to the network. We are now able to ping the PC, read and write to all the Beckhoff channels. Using the epics caget routine, we confirmed that we can read the data from the channels. We have not tried writing to the channels using caget. It is not possible to accidently spin the NCAL since the NCAL comms cable had not been connected from the motor controller to the motor. In addition, we were unable to set up the remote desktop to the NCAL PC since, we were unable to add controls as a remote user to the NCAL PC. It is currently not possible to search the channels using chndump since a DAQ restart would be required to add the new channels names to the channel list.
The new Beckhoff channels are:

* = Read and write channels
The NCAL wiki will have more information with regards to the channel names. The MEDM screen is being populated with the relevant channel names.
To Do:
- Correctly route the cables in the racks.
- Add controls as a remote user to the NCAL PC.
- Connect the optical encoder to the rack.
- Test spin using over epics.
- Test safety/emergency procedures for NCAL.
- DAQ restart to add the Beckhoff channels to the channel list.
- Spin with full IFO.
- Use current PEM sensors and evaluate noise.
- Configure front end model to track optical encoder and provide real time force estimate.
The channels as added by the DAQ restart (LHO alog 52768) for the NCAL front end model are:
