Overview
To execute the desired operations of the machine axis (sequence, position, etc.) in
“Automatic” mode, the FM 353 needs certain information. This information is pro-
grammed with “Parameterize FM 353” (traversing program creation) in the form of
a traversing program, based in principle on DIN 66025.
Traversing programs
Each traversing program is stored under a program number.
A traversing program consists of not more than 100 traversing blocks.
The program number and traversing blocks are converted to an internal format
(see Section 9.3.12), are stored in the appropriate data block, and are transferred
to the module. where they are administered.
The possible number of programs depends on the amount of memory available
(max. 16 Kbytes) and on the length of the individual programs.
Program length in bytes: 108 + (20 x no. of traversing blocks)
Program name
Any program can be assigned a name (optional).
The program name may have up to 18 characters, and is saved with the program.
Program number
Programs may be numbered from % 1 to % 199.
