Corrected cabling for ISCT1 DC PD's and Auxiliary Channels
While doing cabling for HAM6 in the CER, noticed that the following cables for ISCT1 in ISC-C2 were plugged in backwards. Swapped the following at the EtherCAT Corner 5 Chassis. Cables are connected as listed below and match the pull list E12000408.

Cable_ISC_328 connected to Port 9 (DC PD's ISCT1)
Cable_ISC_326 connected to Port 10 (Auxiliary ISCT1)

After fixing the corner beckhoff, we noticed that the PSL persicope PD was still not reading the correct voltage based on yesterday's measurement alog 13222. It turns out that swapping back cable ISC_326 and ISC_328 fixes this problem.

As desgined from D1100583, E1200077:

The Auxiliary ISCT1 cable ISC_326 from Concentrator 1 --> EtherCat Corner Chassis slot 10

DCPDs ISCT1 cable ISC_328  from Concentrator 2 --> EtherCat Corner Chassis slot 9 --> System Manager L9-10 EL3104 Adapter 9

 

The System manager is linked according to the specification above. However, with the proper configuration the readback was not connected. Maybe it's an internal swap in the EtherCat Chassis? We have flipped the cables at the concentrator.

Current Configuration:

The Auxiliary ISCT1 cable ISC_328 from Concentrator 1 --> EtherCat Corner Chassis slot 9

DCPDs ISCT1 cable ISC_326  from Concentrator 2 --> EtherCat Corner Chassis slot 10 --> System Manager L9-10 EL3104 Adapter 9
