2-44 System- and communication configuring D7-SYS - SIMADYN D
Edition 03.2001
The online test mode is normally processed in the background after
initialization was successfully completed. However, if the acknowledge
button is pressed at the end of initialization, then only the service
communications utility is activated.
Errors in the background processing are saved in the UEB element of the
error field SYS_ERR.
2.2.2.1 Online test mode
In the online test mode, for example, a battery test, a memory module
checksum test etc. are executed. The memory module checksum routine
determines the memory module checksum and compares it with the
checksum calculated by the programmer and that saved in the memory
module. If a memory module checksum error is identified in the online
test mode, the user can remove the error by repeatedly generating the
memory module. For battery test errors, he can replace the battery.
