Meaning
Internal module error occurred
•
Possible cause: Technology module de-
•
fective
The received parameter data record is
•
invalid
The configured BaseUnit is not the used
•
BaseUnit
No technology module L+ supply voltage
•
Possible cause: BaseUnit-Incorrect type
•
Technology module cannot send an inter-
•
rupt because a previous interrupt has not
been processed
Possible causes:
•
– Parameter assignment error
– Too many hardware interrupts in too
short a time
No normal operation of the technology
•
module possible
Possible cause: Technology module is
•
performing a firmware update
Technology module defective
H
Firmware error
H
Technology module defective
To correct or avoid errors
Replace technology module
Checking parameter data record
•
Checking BaseUnit
•
Check BaseUnit type
•
Check the wiring of the supply voltage
•
L+ on the BaseUnit
Change interrupt processing in the CPU
•
and re-assign technology module pa-
rameters correspondingly
Checking frequency of the interrupts
•
from the process
Wait until technology module is availa-
•
ble again
If firmware update aborts:
•
– Check minimum firmware version
required
– Check supply voltage
– Repeat firmware update
Replace technology module
Run firmware update
Replace technology module
