5.2 Checking EtherNet/IP Communication State
5.2.1 Unit Annunciation Relays
There are the following unit annunciation relays.
Device Description
R9350 EtherNet/IP preparation done = 1, Other states = 0
R9351 Cyclic communication: All nodes communicating normally =1, Others = 0
R9352 Cyclic communication: All nodes stop =1, Others = 0
R9353 Communication abnormal node exists = 1, None = 0
R9354 EtherNet/IP Start/Stop controllable = 1, Uncontrollable = 0
5.2.2 Cyclic Communication State Tables of EtherNet/IP
There the following types of cyclic communication state tables. They can be monitored by
reading the states using F465 ETSTAT instruction.
Table type Description
Cyclic communication registration
node table
Bit corresponding to the node number that the connection is regsitered
=1, Invalid node = 0
Cyclic communication normal node
table
When the first refresh is complete after connection establishment = 1,
Other states = 0
Cyclic communication stop node
table
Bit corresponding to the node to be stopped when the stop request
processing is complete = 1, Others = 0
Cyclic communication abnormal
node table
Node that the cyclic commuication error occurs =1, Others = 0
Cyclic communication:
RUN/IDLE bit monitor
RUN/IDLE bits received from the targets registered in Scan List
When the following two conditions are met, the bit corresponding to each
node number turns ON (1). In other conditions, it turns OFF (0).
- It is communicating with the target node normally.
- The RUN/IDLE bit received from the target node is in RUN (1)
Note)
The communication condition with the FP0H node connected to the
source is not reflected.
