Determining the Error from the Status

The EST2-2C-MV3 CX-Thermo Support Software's Status Display can be used to monitor the
EJ1 status and related status in a directory tree.
In addition to the status name and details, possible causes of errors and their countermea-
sures are displayed, which enables efficient processing of errors.
The EJ1 status can be checked by using communications to read the Status.
Status is connected to other status data in a directory tree, so the cause of the
error can be checked or the channels for which there are alarms can be inves-
tigated by searching through the directory tree for the related status.
Example of Using Status Information for Troubleshooting
1. Read the Device A Status (C40000) for the TC4 Unit.
C40000: 'H0004 (i.e., bit 2 is ON)
→ A channel error status bit is ON.
2. Read Error Channel A Status (C4000B).
C4000B: 'H0008 (i.e., bit 3 is ON).
→ An error or alarm has occurred for channel 4.
3. Read the Channel Status (C40401) and Channel Alarm Status (C40402)
of channel 4.
C40401: 'H0001 (i.e., bit 0 is ON)
→ Operation is stopped but there is no input error.
C40402: 'H0003 (i.e., bits 1 and 2 are ON)
→ Channel 4 alarms 1 and 2 are ON.
