TOP ServerSystem Tags Overview
Informational and Functional Tags Accessible from the Client Allow Runtime Changes to Many Channel and Device Parameters
Network Adapter Device ID Device Enable/Disable
Provide flexibility and ease of controlling communications parameters from the Client
Client Scripting functionality can also make use of access to System Tags.
System Tags: Different Levels
Three Different System Tag Levels Application/Server Level Channel Level Device Level
Every Channel has a Group of System Tags Every Device has a Group of System Tags
System Tags: Server Level
Informational, Read-Only Tags Some of the More Useful System Level Tags
_ActiveTagCount _ClientCount _Time_Second
Browseable from any OPC Client Suitelink/DDE Clients Use Topic “_ddedata” and a tag
syntax of _System._TagName
System Tags: Channel Level For Ethernet Drivers
Channel Level Tags available depends on Serial or Ethernet
Most Useful System Tags for Ethernet Channel _AvailableNetworkAdapters _NetworkAdapter
Channel Level Suitelink / DDE Topic = ChannelName__System Tag Syntax = _TagName
System Tags: Channel Level For Serial Drivers
Channel Level Tags available depends on Serial or Ethernet
Most Useful System Tags for Serial Channel Tags for COM Parameters (_BaudRate, etc.) _ComID
Channel Level Suitelink / DDE Topic = ChannelName__System Tag Syntax = _TagName
System Tags: Device Level
Most Useful Device Level Tags Timeout Based (_RequestTimeout, etc.) _Error / _NoError Tags _Enabled Tag _DeviceID Tag
Device Level Suitelink / DDE Topic = ChannelName_DeviceName__System Tag Syntax = _TagName
System Tags: Siemens Ethernet
Special System Tags for Siemens S7 PLCs Used for Controllers with Redundant CPUs
_Rack _Slot

Case Study Success – SAB Alrode Questions & Answers
Special Considerations for ControlLogix Addressing
PLC addressing is not traditional “N7:0” style – it’s in tags - also called “Native Tag Addressing” – which are useful for PLC programming and save time there, but . . .
Traditional “blocking” of data in the PLC has little value
PLC communications protocol requires driver to put actual tagnames into packet
Packet request size limited to about 500 bytes
PLC “local program” tags add additional overhead to the request packet
Since each timer, counter, PID loop, Alarm Block is a structure with numerous sub-elements, and you can nest structures inside of structures and define your own strutures, the potential for explosion to thousands of tags is high
AB ControlLogixAddressing
Special Considerations for ControlLogix needed to ensure best performance with the new paradigm in programming and communications:
Arrays are highly efficient means of moving large blocks of data and circumventing request packet limits
Keep PLC tag names short
Use global tags wherever possible
If you don’t need it, don’t read it!
Be particularly careful to group your tags by required scan rate – don’t read it faster than you need it “just because its Ethernet” or “faster is better”!
Be careful of large numbers of Programs in a Logix project. Increased overhead on the processor can result in no time left for actual communications!
For Continuous Tasks, Communications Timeslice % >= 20%
ControlLogix Connectivity – Ways to Optimize
AB Suite – ControlLogix Tips
Maximizing Performance Use multiple channels on Ethernet Put high frequency writes on a separate
channel Use symbolic & physical modes on
ControlLogix where appropriate Separate channels for each protocol mode If > 1/3 of all tags in PLC requested, Physical
Blocking faster than non-blocking Using < 1/3 of items in a structure – Physical Non-
Blocking Using > 1/3 of items in a structure – Physical
Blocking Atomic tags – Physical Non-Blocking
