DeviceLogix
Embedded control
Function as stand-alone or complimentary to supervisory control
Used to control outputs and manage status information locally within the drive
Can integrate with the drive or operate independently
Use 24vDC Aux Power Supply option to allow operation with 3-phase input power disconnected
The PF755 has embedded DeviceLogix capability. This provides the ability to function as a stand-alone system or operate complimentary to a controller.
The PF755 DeviceLogix can work with the drive:
Control Logic Command bits (Start, Stop, etc.)
Control the Speed Reference
Monitor Logic Status bits
Monitor Speed Feedback
Read & write parameters
The PF755 DeviceLogix can also operate independently:
Read inputs and write outputs on I/O options
If a 24vDC Aux Power Supply option is also used, the DeviceLogix can continue operating when 3-Phase input power is disconnected.

5. Does NOT count as a Function Block
PowerFlex 755
DeviceLogix
Function Block programming (90 Function Blocks max.)
Instruction Types include:
Bit & Analog I/O
Process
Filter
Select / Limit
Statistical
Timer / Counter
Compare
Compute / Math
Move / Logical
Does NOT count as a Function Block
Each instance counts
as one Function Block
Up to 90 Function Blocks max. are allowed. Bit & Analog I/O instructions do not count against the maximum, but each instance of the other instructions count as 1 Function Block for each. For example, a TONR, ADD, and BAND count as 1 Function Block each.
The PF755 supports Version 3 of the DeviceLogix library, which includes several new analog instructions such as Compute / Math.
Other DeviceLogix-based devices may be using earlier versions of the DeviceLogix library and may not support some of the instructions above. Please refer to the respective user manual of each device to determine its DeviceLogix capabilities.

PowerFlex 755
DeviceLogix
90 Function Blocks maximum
What it can do:
It is designed for basic logic capability for applications that can allow a 5-10ms scan time plus the time it takes to update the I/O
5ms scan time for the first 45 function blocks
Additional 5ms scan time for the remaining 45 function blocks
10ms total for 90 function blocks
Provide Selector Switch functionality similar to the PF700S
Provide Scale Block functionality similar to the PF700VC
What it can NOT do:
It is NOT a PF700S DriveLogix replacer
It is NOT a 1336 FORCE Function Block replacer
Other DeviceLogix-based devices may have more or less Function Blocks, and may have faster or slower scan times. Please refer to the respective user manual of each device to determine its DeviceLogix capabilities.

18. DeviceLogix Editor Example Instruction Properties button
Must select the proper
type of data used
Access to an instructions properties is done via the Properties button.
Some instructions support variable data types and typically default to DINT. A common mistake is to use REAL parameters (common data type on PF755) with a DINT data type for the instruction. This will result in the fraction being truncated. Seeing a whole number (no fraction) is the tell-tale sign that the instruction data type is not REAL.
Some instructions can also have the number of inputs increased.

Can use constants for comparisons if desired
Instructions can be individually enabled
