Page 15: Conventions
Several parts of this manual refer to the controller's software revisions. These revisions are marked with the assigned Mecc Alte code (shown on the rear panel of the controller). Software code version has the following format: EB0250231XXYY, where "XX" is the main revision number and "YY" is the secondary revision number. Thus, the code EB02502310100 refers to the controller's software release "1.00".
