Error code 1: “Hardware and configuration error”
Error
Argument
Error Description
Solution
-
Invalid check sum in
the parameter area
of the fieldbus
coupler.
1. Turn off the power supply for the node.
2. Replace the fieldbus coupler.
3. Turn the power supply on again.
1
Overflow of the
internal buffer
memory for the
attached I/O
modules.
1. Turn off the power for the node.
2. Reduce the number of I/O modules.
3. Turn the power supply on again.
4. If the error persists, replace the fieldbus controller.
2
I/O module(s) with
unknown data type
1. Determine the faulty I/O module by first turning off the
power supply.
2. Plug the end module into the middle of the node.
3. Turn the power supply on again.
4. - LED continues to flash? -
Turn off the power supply and plug the end module into
the middle of the first half of the node (toward the fieldbus
controller).
- LED not flashing? -
Turn off the power and plug the end module into the
middle of the second half of the node (away from the
fieldbus controller).
5. Turn the power supply on again.
6. Repeat the procedure described in step 4 while halving
the step size until the faulty I/O module is detected.
7. Replace the faulty I/O module.
8. Inquire about a firmware update for the fieldbus controller.
3
Unknown module
type of the
Flash program
memory
1. Turn off the power supply for the node.
2. Replace the fieldbus controller.
3. Turn the power supply on again.
4
Fault when writing in
the Flash program
memory.
1. Turn off the power supply for the node.
2. Replace the fieldbus controller.
3. Turn the power supply on again.
5
Fault when deleting
the Flash memory.
1. Turn off the power supply for the node.
2. Replace the fieldbus controller.
3. Turn the power supply on again.
6
The I/O module
configuration after
AUTORESET differs
from the
configuration
determined the last
time the fieldbus
controller was
powered up.
1. Restart the fieldbus controller by turning the power supply
off and on.
7
Fault when writing in
the serial EEPROM.
1. Turn off the power supply for the node.
2. Replace the fieldbus controller.
3. Turn the power supply on again.
