NOTE
1 This is the number of ladder steps for the program only with basic instructions. The use of
functional instructions may vary the number of ladder steps.
2 The size of a symbol and that of a comment are fixed to 32KB.
The size of a message is fixed to 2.1KB.
The maximum size of a symbol and that of a comment are 64KB each.
3 These have no limit of size for each. However, the total size of sequence program (the sum total
of ladder, symbols/comments, messages, etc.) never exceed the storage size of sequence
program. The size of them influences the capacity of others.
4 FLASH ROM is used in the FANUC Series 20.
5 As values indicated with an asterisk (*) in the table, former versions of the programming manual
and catalogs have listed the mean processing time of basic commands, but this manual lists
the execution time for one step. The actual ladder program execution performance (speed) of
each PMC has not been changed.
6 Application PMC for FANUC Series 16–MODEL A loader control function is PMC–SA1.
