TSC PICO motor driver turned back on.
Jennie W. called to let me know that they need the Pico Motor Drivers turned back on.

Faulty network cable linking the Slow Controls Corner 2 Chassis and Corner 3 Chassis caused intermediate connection issues. Issue first noted when SPI crew tried to enable the TCSY picomotor driver and found it unresponsive. Verified the CER and field driver both were powered on. Beckhoff overview screen showed no issues. The field driver chassis was power cycled. No change. Tried to enable the TCSX driver, same issue. CDS overview screen eventually showed Beckhoff issues. Patrick logged into the system and confirmed all terminals past chassis 2 were not being seen by the system. Removing the lid on the Corner 3 Chassis showed all network LED’s on the EtherCAT couplers were OFF. Cable replaced network LED's on. Verified the TCSY driver can be enabled/disabled.
