Fundamentals of COM 266
Data area:
The data area of a screen form provides information on
• the machine data
• the defaults
• the configuration parameters
• Traversing (machining) programs
The data area is subdivided into the following fields:
• Fields with fixed texts
A fixed text describes the relevant item of data.
Input fields are displayed in reverse video. These fields are shown in the
manual on a gray background. You may change the contents of these fields.
• Output fields
An output field provides information on data already entered. In the screen
forms, an output field is always preceded by a colon. Data in an output field
cannot be changed.
Error line:
If errors occur during program execution, an appropriate error message is dis-
played on this line. Auxiliary messages and control information are also displayed
on the error line. Each error message comprises an error code followed by an
error text. The same error code is entered in the error byte in the STEP 5 message
block.
