5. OPERATION
5.7.6 The note if the step sequence function is selected when setting a
model
When using the step sequence method, mnemonic instructions cannot be coded.
The mnemonic conversion functions need following notes:
1)
2)
3)
Programming by Mnemonic instructions
A step sequence program cannot be created with mnemonic instructions. It is impossible to
create a step sequence program with a text editor, or to read the program into FAPT LADDER
by means of mnemonic-to-source conversion.
Source-to-Mnemonic and Mnemonic-to-Source Conversions
If source-to-mnemonic conversion is executed for a step sequence source program, only ladder
subprograms are converted to mnemonics, step sequence subprograms being ignored. If a
step sequence source program is subjected to source-to-mnemonic conversion, then to
mnemonic-to-source conversion, the original source program will not be replicated.
Source Program Conversion using Mnemonics
A program can be converted by using mnemonics, as shown below:
I PMC-RB3
, * PMCRC3
1
t
(STEP SEQ)
A program for the PMC-FIB4 (STEP SEC?) cannot be converted for use with the PMCRC4
(STEP SEC), because of the reason explained in Section 7.2. The program can be converted
if a ROM file is used, however. (For details of this conversion, see the description of the
decompiler.)
