Optimized Packets
Select
DDE/OPC > Optimized Packets
to display the optimized network traffic for all DDE Topics. The DDE Server optimizes the network traffic based on the largest packet size for the network route. This reduces the number of packets required to retrieve data from the PLC. The following items display information about the state of the optimized packets. Refer to Optimized packet states for ControlLogix packet state information.Route | The DDE topic associated with the optimized packet. |
Start Item | The first item of the optimized packet. |
End Item | The last item of the optimized packet. |
Item Count | The number of items in the optimized packets. For non-ControlLogix items, this is all items in the optimized packet. For ControlLogix, this is the number of items in a ControlLogix optimized packet. The ControlLogix item count is determined after it is optimized as an array. |
Packets Sent | The number of solicited packet requests sent for this optimized packet. |
Packets Received | The number of solicited packet responses received for this optimized packet. |
Valid Packets | The number of good solicited responses received for this optimized packet. |
Invalid Packets | The number of error solicited responses received for this optimized packet. |
Unsol Packets Received | The number of unsolicited packets received for this optimized packet. |
Packets/sec | The number of solicited packets per second received on this optimized packet. |
Unsol Packets/sec | The number of unsolicited packets per second received on this optimized packet. |
Packet State | Displays whether the packet is active or inactive. For ControlLogix, displays what state the packet is in communicating with the processor that is adding/removing items to be requested. |
Reinitializations | The number of times RSLinx Classic has had to rebuild and restart handling a ControlLogix optimized packet due to a broken connection, or a state that RSLinx Classic could not recover the packet. |
