Chapter 4 Configuring the I/O
ADC can also work in tandem with Firmware Supervisor. If Firmware Supervisor
is set up and enabled for a drive (‘Exact Match’ keying must be used), the drive/
peripheral will be automatically upgraded (if necessary) prior to any ADC
operation for that port.
Version 4.01 Drive Add-on Profiles (AOPs)
RSLogix 5000 software, version 20.00 ships with version 4.01 Drive Add-on
Profiles (AOPs). Note the following ADC operating status when using version
4.01 Drive AOPs:
• When adding a new drive, ADC is enabled by default for any drive that
supports ADC, such as PowerFlex 753 drives with firmware 7.001 or later,
or PowerFlex 755 drives with firmware 4.001 or later.
TIP Use with select Stratix switches to provide dynamic IP address assignment by
port (requires one drive per port). This eliminates the need for the user to
manually enter the IP address, Subnet mask, and Gateway address prior to
connecting a replacement drive to the Ethernet network.
IMPORTANT Logix ‘owns’ the configuration of the drive. ADC will be triggered any
time the Logix controller detects a configuration signature mismatch
when establishing an EtherNet/IP network I/O connection.
The use of other configuration tools, such as a HIM, DriveExplorer software, or
DriveTools SP software, should be minimized and restricted to monitor-only
operation. Any configuration changes made by these tools will cause a
configuration signature mismatch the next time the Logix controller connects
to the device and ADC will write over any changes made by the other tools.
Consider using the Write Mask function (drive Parameter 888 - [Write Mask
Cfg]) to prevent tools connected to ports other than the Embedded EtherNet/IP
port in a PowerFlex 755 drive from writing to the drive. Any drive configuration
changes should be made with the RSLogix 5000 Add-on Profile (AOP).
The use of Explicit Messaging to perform parameter writes in the user’s Logix
program should be limited to RAM memory by setting the proper Attribute in
the MSG instruction. Any writes to parameter nonvolatile storage (EEPROM)
memory will clear the configuration signature and cause a mismatch the next
time the Logix controller connects to the device. This will trigger ADC, which
will write over any changes that were previously made.
TIP When enabling ADC in your control system, adhere to the following
recommendations:
• Enable ADC as the last step, that is, after drive configuration and
commissioning is completed. This eliminates time being wasted from
‘nuisance’ ADC downloads being triggered after any parameter changes
are made.
• Upload the configuration from a drive prior to enabling ADC for it. This
ensures the drive’s configuration in the project matches the actual drive.
• Enable and test ADC with one drive prior to enabling it for the entire
control system. ADC can be tested by changing a parameter in a port, such
as with a HIM, and resetting or cycling power to the drive.
