Detailed Drive Operation Chapter 1
Security The security feature provides write access protection for individual
communication ports in a drive. The PowerFlex 700S Phase II drive must be
firmware version 3.003 or higher in order to support this feature. In addition, the
following drive peripherals and software tools support the security feature:
Communication Peripherals
• 20-COMM-E EtherNet/IP v2.002 (or higher)
• 20-COMM-C/-Q ControlNet v2.001 (or higher)
• 20-COMM-D DeviceNet v2.001 (or higher)
• 20-COMM-S DF1 v1.003 (or higher)
Software Tools
• DriveExplorer v4.04 (or higher)
• DriveTools SP v4.01 (or higher)
By default, every DPI port in the drive is configured to allow write access. To
change write access on an individual DPI port, change the bit setting of the
associated port in parameter 669 [Write Mask].
• Bit 0 = “Terminal Blk” (drive)
• Bit 1 = “Local HIM” (DPI Port 1)
• Bit 2 = “Ext DPI Conn” (DPI Port 2)
• Bit 3 = “Aux DPI Conn” (DPI Port 3)
• Bit 5 = “Int DPI Comm” (DPI Port 5)
• Bit 7 = “DriveLogix”
A bit value of 0 = masked (read only access)
A bit value of 1 = not masked (read/write access)
Any changes to [Write Mask] will not take effect until one of the following events
happen:
• Power is removed and reapplied
• A drive reset (not reset to defaults) is performed
The status of a port's write access may be verified at parameter 712 [Write Mask
Act]. For example, to verify that write access was disabled on “DPI Port 1”, bit 1
of [Write Mask Act] should equal bit 1 of [Write Mask]. Note that bit 15
“Security” of [Write Mask Act] is for future use.
The port that is being used to make security changes (e.g. if using a network
adapter connected to port 5), can only change other ports (not itself ) to “Read
Only.” This feature prevents the complete lockout of a drive with no way to regain
write access.
