16.3 CPU-Oriented Message Configuration
16.3.1 How to Assign CPU-Oriented Message Numbers
Messages of the CPU are identified by a unique number. This is done by assigning each CPU a
number area. Other than for assigning project-oriented message numbers, there is no need to
assign a new number area to the new program. A new compilation of the program is therefore not
required. Note the exception when you copy individual blocks: In this case, you must recompile the
program in order to implement the modified message number.
Requirements
• WinCC V6.0
• ProTool V6.0
