3.1.3.4 Firmware status, ECL, ECO connection
Central coupling blocks, which communicate with a firmware (e. g.
@CSD01 or @CSH11) have outputs ECL and ECO.
The outputs ECL and ECO indicate the status of the appropriate
firmware:
• ECL=0 and ECO=0:
The firmware is in an error-free condition.
• ECL=0 and ECO>0:
The firmware has an error condition, which can be rectified by the
configuring engineer or user. The error cause is described in the
Chapters associated with the individual couplings.
• ECL>0 and ECO>0:
An irreparable firmware error is present.
3.1.3.5 Status display, output YTS
The block outputs an error code or the instantaneous data transfer status
at its output YTS.
• Real (severe) run-time errors
• Configuring errors, which are identified when the system is initialized,
and which are displayed at the 7-segment display of the CPU using a
flashing "C".
• Temporary status displays and alarms
