Error code 1: "Hardware and configuration error"
Error
Argument
Error Description
Solution
1
Overflow of the
internal buffer
memory for the
attached I/O
modules.
1. Turn off the power supply of the node.
2. Reduce the number of I/O modules.
3. Turn on again the power supply of the node.
4. If the error persists, replace the head station.
2
I/O module(s) with
unknown data type
1. Determine the faulty I/O module. First turn off the power
supply of the node.
2. Plug the end module into the middle of the node.
3. Turn on again the power supply of the node.
4. - LED continues to flash? -
Turn off the power supply of the node and plug the end
module into the middle of the first half of the node (toward
the head station).
- LED not flashing? -
Turn off the power supply of the node and plug the end
module into the middle of the second half of the node
(away from the head station).
5. Turn on again the power supply of the node.
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. Contact I/O support and inquire about a firmware update
for the head station.
3
Invalid check sum in
the parameter area
of the head station.
1. Turn off the power supply of the node.
2. Replace the head station.
3. Turn on again the power supply of the node.
4
Fault when writing in
the serial EEPROM.
1. Turn off the power supply of the node.
2. Replace the head station.
3. Turn on again the power supply of the node.
5
Fault when reading
the serial EEPROM
1. Turn off the power supply of the node.
2. Replace the head station.
3. Turn on again the power supply of the node.
6
The I/O module
configuration after
AUTORESET differs
from the
configuration
determined the last
time the head station
was powered up.
1. Restart the head station by turning the power supply off
and on.
7
Invalid hardware-
firmware
combination.
1. Turn off the power supply of the node.
2. Replace the head station.
3. Turn on again the power supply of the node.
8
Timeout during serial
EEPROM access.
1. Turn off the power supply of the node.
2. Replace the head station.
3. Turn on again the power supply of the node.
