UE4740 EFI gateway
Status information
Meaning/effect
I/O error [Byte 1, Bit 1]
•
Logical 0, if there is no error on the EFI gateway
•
Logical 1, if there is an error on the EFI gateway
Note:
The I/O error is calculated automatically
from the validity of the data on the interfaces
connected and as a function of the usage of the
data (in the gateway routing). Indicates that the
data on this EFI interface are currently invalid
and represent substitute values. This situation
occurs, for example, on EFI gateways if the
controlling (F)PLC is not (yet) operating.
All except [Byte 1, Bit 1]
•
Freely programmable signals correspond to the
requirements for the EFI devices connected
Control feature
Meaning/effect
I/O error [Byte 1, Bit 1]
•
Logical 0, if there is no error on a connected
device
•
Logical 1, if there is an error on a connected
device
Note:
Indicates that the data on this EFI
interface are currently invalid.
All except [Byte 1, Bit 1]
•
Freely useable information for further data
routing.
Note:
On the usage of this information the status
of the received I/O error bits is also to be
evaluated.
