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.

8
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

9
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

10
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

11
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

12
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

13
System Tags Siemens Ethernet

• Special System Tags for Siemens S7 PLCs
• Used for Controllers with Redundant CPUs
• _Rack
• _Slot
• Device Level Suitelink / DDE
• Topic ChannelName_DeviceName
• Tag Syntax _TagName

TOP ServerAlias Map

• Allows Creation of Friendly Topic Names
• Eliminates Channel_Device Syntax
• Useful for Creating Shorter Topic Names for Use
  in Clients
• Can Map Multiple Aliases to the Same
  Channel/Device
• Useful For Viewing Valid Topics
• Scan Rate Override

AB ControlLogixAddressing

• Special Considerations for ControlLogix
  Addressing
• PLC addressing is not traditional N70 style
  its 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

18
ControlLogix Connectivity Ways to Optimize

• 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 dont need it, dont read it!
• Be particularly careful to group your tags by
  required scan rate dont 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

19
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 gt 1/3 of all tags in PLC requested, Physical
  Blocking faster than non-blocking
• Using lt 1/3 of items in a structure Physical
  Non-Blocking
• Using gt 1/3 of items in a structure Physical
  Blocking
• Atomic tags Physical Non-Blocking

TOP Server Modbus Ethernet

• Key Performance Features
• Configurable Protocol Settings
• Zero/One Based Addressing Bit Access
• Reverse Bit/Byte/Word/Dword Ordering
• Configurable Block Size (Registers Coils)
• 5 Device Models (For Non-Standard
  Implementations)
• Configurable Socket Usage per Device
• Maximizes throughput for devices supporting
  multiple socket connections
• Can be restricted to single socket per channel
  for devices only supporting a single socket
  connection
