Appendix C Using DeviceLogix
Import and Export The ArmorStart EtherNet/IP AOP provides users an import or export function.
The export function allows the DeviceLogix program to be saved to a file. This
file can then be imported into a similar product of same function regardless of
horsepower. Importing of DeviceLogix between unlike products is not allowed,
e.g. Bulletin 284E and Bulletin 280E.
Bulletin 284 - VFD Preset
Speed Example DeviceLogix can be used to select one of multiple preset frequencies
cooperatively with the PLC or independently based on user input. This can be
done using the four digit inputs or the frequency control bits in DeviceLogix.
The digital inputs provide the user the most flexibility, but can be more complex
to configure. If a preset speed is needed, the simpler approach is to use frequency
control found in the produced network bits of DeviceLogix. If you prefer not
to apply DeviceLogix for preset speeds, then implement the digit inputs to select
preset speed via Instance 166 found in Chapter 5. The following example will
demonstrate the use of frequency control bits in DeviceLogix
Frequency control (Freq Cntl) bits allow a maximum of 4 Preset Speeds, each
preset has a predefined accel or decel reference. If more are required then digital
inputs must be configured and properly used. The example will focus on
Frequency Control 2,1,0 in the Produced Network Bit
Table 52 . Note that there
are other capabilities shown in the table that are not reviewed in this example.
Figure 100 below shows all of the available network outputs supported by
Bulletin 284.Referring to Table 52 the preset frequencies are defined in
parameter 170,171,172 and 173 of Bulletin 284. Also note the truth table that
selects each of those frequencies. For example if Freq Cntl bit 2=1, 1=1, and 0=0
then the controller frequency is based on Parameter 172 (Preset Freq 2).
