Following rules apply for the usage of input bit
commands:
•
Only one iVu input bit can be set at a time.
•
Corresponding ACK bits are only set high on
completion of the command (if the iVu input bit
is still high).
•
Corresponding ACK bits are cleared when the iVu
input bit is cleared.
•
When multiple iVu input bits are set
simultaneously, the Execution Error input bit is
set and an Error Code value is reported in the
Error Code register.
•
The Execution Error iVu output bit is cleared
when all ACK bits get cleared, or a new valid
command is received.
9.4 EtherNet/IP
The iVu Plus device is controlled via EtherNet/IP using assembly objects. From the point-of-view of a PLC, there are three
input assemblies and two output assemblies.
The Originator of the EtherNet/IP connection is the PLC. The Target of the EtherNet/IP connection is the iVu Plus. The
direction of communication can be described as T > O or O > T (sometimes also shown as T2O or O2T).
