DF1 Protocol – half and full duplex
Sometimes also called “DF1 Channel 0”
Available on many PLC CPUs directly and also via KF3, KF2,
and KE interfaces
DH+ (via KT, KTX, KTX, PKTX, PKTXD, PCMK or SST cards)
DH-485 (via KTX, KTX, PKTX, PKTXD, or PCMK cards)
ControlNet (via ControlLogix Gateway)
Ethernet

Standard TCP/IP with AB proprietary protocol in Layer 7
(application layer)

Protocol Modes
 Three Different Protocol Modes:
 Symbolic Mode
 The traditional protocol when Logix processors were first
introduced
 Uses the full ASCII character name of an address
 Used exclusively through Driver Version 4.6.0.xx
 Physical Modes (Non-Blocking and Blocking)
 Upload sequence at beginning pre-maps addresses in the
controller using their physical address.
 Slower startup, but much higher performance with larger address
counts, as more data can be retrieved in a single request
 Avoids Symbolic Address parsing and lookup for greater
efficiency in communications.
ControlLogix Ethernet
Configuration Optimizations

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 NonBlocking
Using > 1/3 of items in a structure – Physical
Blocking
Atomic tags – Physical Non-Blocking
AB ControlLogix
Addressing
 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 structures, the potential for
explosion to thousands of tags is high
ControlLogix Ethernet Tag
Import
 Two Import Options:
 Import from the Controller
 Pros: Fast / All tags including I/O imported
 Cons: Controller access required / Descriptions are not imported
 Import from L5K / L5X File
 Pros: No Controller Access Necessary / Descriptions imported
 Cons: Slow / No I/O Tags imported
 Importing Ensures Proper Tag Syntax
ControlLogix Connectivity –
More 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 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%
