TCU2 communication errors on new HFO4 system
Symptom
TCU2 Communication Errors on HFO4. The TCU was generating communication errors in the system error log and the /usr/g/service/log/temperature_log.data file did not contain any data. The system is a HFO4 running HFO4 M3 software. New system install. The system has the TCU2 model of TCU. The host communication to the TCU2 is failing. We see an error initializing TCU's in the gesys log, and we see numerous errors in the /usr/g/service/log/tcuErrors file, also the /usr/g/service/log/temperature_log.data file shows “dashes” for each channel temperatureand duty cycle as seen below: {sdc@bay12a}[3] cd /usr/g/service/log {sdc@bay12a}[4] more temperature_log.data 10/26/2004 09:43:22 10/26/2004 09:43:22 [channel1]Temp ----C Duty: -----% 10/26/2004 09:43:43 10/26/2004 09:43:43 [channel2]Temp ----C Duty: -----% 10/26/2004 09:44:04 10/26/2004 09:44:04 [channel3]Temp ----C Duty: -----% 10/26/2004 09:44:25 10/26/2004 09:44:25 [channel4]Temp ----C Duty: -----% 10/26/2004 09:44:46 10/26/2004 09:44:46 [channel5]Temp ----C Duty: -----% 10/26/2004 09:45:07 10/26/2004 09:45:07 [channel6]Temp ----C Duty: -----% 10/28/2004 09:36:44 10/28/2004 09:36:44 [channel1]Temp ----C Duty: -----% 10/28/2004 09:37:05 10/28/2004 09:37:05 [channel2]Temp ----C Duty: -----% 10/28/2004 09:37:26 10/28/2004 09:37:26 [channel3]Temp ----C Duty: -----% 10/28/2004 09:37:47 10/28/2004 09:37:47 [channel4]Temp ----C Duty: -----% 10/28/2004 09:38:08 10/28/2004 09:38:08 [channel5]Temp ----C Duty: -----% 10/28/2004 09:38:29 10/28/2004 09:38:29 [channel6]Temp ----C Duty: -----% 10/28/2004 10:43:48 10/28/2004 10:43:48 [channel1]Temp ----C Duty: -----% 10/28/2004 10:44:09 10/28/2004 10:44:09 [channel2]Temp ----C Duty: -----% 10/28/2004 10:44:30 10/28/2004 10:44:30 [channel3]Temp ----C Duty: -----% 10/28/2004 10:44:51 10/28/2004 10:44:51 [channel4]Temp ----C Duty: -----% 10/28/2004 10:45:12 10/28/2004 10:45:12 [channel5]Temp ----C Duty: -----% 10/28/2004 10:45:33 10/28/2004 10:45:33 [channel6]Temp ----C Duty: -----% 11/05/2004 10:29:06 11/05/2004 10:29:06 [channel1]Temp ----C Duty: -----% 11/05/2004 10:29:26 11/05/2004 10:29:26 [channel2]Temp ----C Duty: -----% 11/05/2004 10:29:47 11/05/2004 10:29:47 [channel3]Temp ----C Duty: -----% 11/05/2004 10:30:08 11/05/2004 10:30:08 [channel4]Temp ----C Duty: -----% 11/05/2004 10:30:29 11/05/2004 10:30:29 [channel5]Temp ----C Duty: -----% 11/05/2004 10:30:50 11/05/2004 10:30:50 [channel6]Temp ----C Duty: -----% 11/11/2004 11:14:46 11/11/2004 11:14:46 [channel1]Temp ----C Duty: -----% 11/11/2004 11:15:07 11/11/2004 11:15:07 [channel2]Temp ----C Duty: -----% 11/11/2004 11:15:28 11/11/2004 11:15:28 [channel3]Temp ----C Duty: -----% 11/11/2004 11:15:49 11/11/2004 11:15:49 [channel4]Temp ----C Duty: -----% 11/11/2004 11:16:10 11/11/2004 11:16:10 [channel5]Temp ----C Duty: -----% 11/11/2004 11:16:31 11/11/2004 11:16:31 [channel6]Temp ----C Duty: -----% 11/12/2004 16:11:13 11/12/2004 16:11:13 [channel1]Temp ----C Duty: -----% 11/12/2004 16:11:34 11/12/2004 16:11:34 [channel2]Temp ----C Duty: -----% 11/12/2004 16:11:55 11/12/2004 16:11:55 [channel3]Temp ----C Duty: -----% 11/12/2004 16:12:16 11/12/2004 16:12:16 [channel4]Temp ----C Duty: -----% 11/12/2004 16:12:37 11/12/2004 16:12:37 [channel5]Temp ----C Duty: -----% 11/12/2004 16:12:58 11/12/2004 16:12:58 [channel6]Temp ----C Duty: -----% 11/16/2004 12:34:22 11/16/2004 12:34:22 [channel1]Temp ----C Duty: -----% 11/16/2004 12:34:43 11/16/2004 12:34:43 [channel2]Temp ----C Duty: -----% 11/16/2004 12:35:03 11/16/2004 12:35:03 [channel3]Temp ----C Duty: -----% 11/16/2004 12:35:24 11/16/2004 12:35:24 [channel4]Temp ----C Duty: -----% 11/16/2004 12:35:45 11/16/2004 12:35:45 [channel5]Temp ----C Duty: -----% 11/16/2004 12:36:06 11/16/2004 12:36:06 [channel6]Temp ----C Duty: -----% 11/16/2004 14:19:33 11/16/2004 14:19:33 [channel1]Temp ----C Duty: -----% 11/16/2004 14:19:54 11/16/2004 14:19:54 [channel2]Temp ----C Duty: -----% 11/16/2004 14:20:15 11/16/2004 14:20:15 [channel3]Temp ----C Duty: -----% 11/16/2004 14:20:36 11/16/2004 14:20:36 [channel4]Temp ----C Duty: -----% 11/16/2004 14:20:57 11/16/2004 14:20:57 [channel5]Temp ----C Duty: -----% 11/16/2004 14:21:18 11/16/2004 14:21:18 [channel6]Temp ----C Duty: -----%
