Continued
Only digital I/O signals can be cross connected.
Consequences
The cross connection has been rejected, and no functions
depending on it will work.
Recommended actions
Remove the non-digital I/O signal from the cross connection.
71052, Max number of cross connections
exceeded
Description
The I/O configuration is invalid.
The maximum number of cross connections, arg , in the I/O
system has been exceeded.
Consequences
Not all the cross connections have been accepted.
Recommended actions
Modify the configuration of the I/O system (by reducing the
number of cross connections) so that the maximum limit is not
exceeded.
71054, Invalid signal type
Description
The I/O configuration for I/O signal arg is invalid.
The specified signal type arg is invalid/unknown.
Valid signal types are: DI (Digital input). DO (Digital output). AI
(Analog input). AO (Analog output). GI (Group input). GO (Group
output). This I/O signal has been rejected.
Recommended actions
Correct the signal type of the I/O signal.
71058, Lost communication with I/O device
Description
The previously working communication with I/O device arg with
address arg on network arg has been lost.
Consequences
It is not possible to access the I/O device itself or I/O signals
on the I/O device since it is currently not communicating with
the controller.
Probable causes
The I/O device may have been disconnected from the system.
Recommended actions
Make sure that the network cable is connected to the controller.
Make sure the I/O device is correctly powered. Make sure the
cabling to the I/O device is correctly connected.

Recommended actions
Check the device or connection.
71077, Communication error from rtp1
Description
Not possible to deliver the received message.
Recommended actions
Check the communication flow.
71078, Communication error from rtp1
Description
The response from the device has an invalid frame sequence.
Recommended actions
Check for noise on the serial line.
71080, Max number of device predefined types
exceeded
Description
The I/O configuration is invalid.
The maximum number, arg, of device predefined types in the
I/O system has been exceeded.
Recommended actions
Modify the configuration of the I/O system (by reducing the
number of device predefined types) so that the maximum limit
is not exceeded.
71081, Max number of physical I/O signals
exceeded
Description
The I/O configuration is invalid.
The maximum number, arg, of physical I/O signals
(bit-mappings) in the I/O system has been exceeded.
Recommended actions
Modify the configuration of the I/O system (by reducing the
number of physical I/O signals) so that the maximum limit is
not exceeded.
71082, Max number of user I/O signals exceeded
Description
The I/O configuration is invalid.
