Safety Block Renaming
General With Release 7 of the Connected Components Workbench (CCW) and
Release 7 of the CR30 firmware, the names of both the safety monitoring
functions and safety output functions can be edited. The editing rules follow
IEC 61131-3, section 2.1.2.
This feature is important because it allows you to distinguish between multiple
occurrences of the same function blocks during the design, wiring, and
troubleshooting phases.
The name change is initiated in one of two ways:
1. Simply double-click the name inside the block
2. Highlight the block and press F2.
The typical editing keys (Home, End, Backspace, Delete, Left Arrow, Right
Arrow, Page Up, Page Down, and Mouse Click) can be used to edit the name.
When the block is selected for editing, the name appears in a light blue box, and
the name is highlighted in light blue background, as shown in
Figure 27 .

Follow these simple rules for naming the blocks:

• Names cannot have spaces
• Names can contain letters, numbers, and underscores (no special
characters)
• Name length can be anywhere from 1…30 characters
• Letter case is not significant
• Multiple leading or consecutive embedded underscores are not allowed
• Trailing underscores are not allowed
