The patch data in these examples is provided only for the purposes of
illustrating the code patch operation. Obtain actual code patch data for
your controller’s firmware version from your Digital representative.
7.3.11.5 Special Code Patch Considerations
Consider the following when using the Code Patch option of the CLCP utility:
• The controller reserves enough non-volatile memory for approximately ten
(10) patches. However, this number varies according to the size of the patches
you enter.
• Patches are hierarchical. In other words, patch number 1 must be entered
before you enter patch number 2, and so on. Furthermore, there are no
‘‘0’’ patches. Patches are always numbered sequentially beginning with the
number 1. You must follow this sequence for each firmware version.
• Because of the hierarchical patch structure, removing any patch also removes
all higher numbered patches. For example, deleting patch number 2 also
removes patches 3, 4, and so on.
• Controllers in dual-redundant configurations must have the same patches
applied and patches must be entered into each controller separately.
7.3.11.6 Exit Option
Select this option to terminate the Code Patch program. Pressing Ctrl/Y at any
time during the Code Patch program performs the same function.
