Symbols
The Symbols tab allows settings to be applied to the symbol table during a work session. Use the following
procedure to change Symbol preferences.
1, 2, 3...
Auto Generation
The Automatically generate symbol names option determines whether 'unnamed' symbols (i.e. symbols that are
created with an address and comment but no name) are automatically assigned symbol names using the
"AutoGen_" prefix, or whether the symbol name is just left blank.
When the option is checked on the following rules apply:
1. When an 'unnamed' symbol is created it will automatically be assigned a name, based on the address (e.g.
an 'unnamed' symbol with address 7.15 will be called "AutoGen_7_15").
2. When the option is checked on it will be possible to reference "AutoGen_" symbols like any other symbols
(Hence, using Find/Replace, Watch Window etc).
5. Select the default CPU from the CPU field. When a new PLC is created, these details
will be used to initialize it. A PLC type and CPU combination may be selected, or the
Use Current PLC button can be pressed, to set the details to that of the currently selected
PLC in the project.
6. Set the Use Section marker instruction option to select whether, by default for a new
PLC, section divisions are to be downloaded or not. If set, an extra instruction is hidden
in the program for each section division. This allows upload options such as the upload
of a single section. It also allows the section structure to be retained upon upload. If the
option is turned off for a PLC, then the section structure will not be downloaded, and
upload will not retain the structure.
Note that this option can be enabled / disabled per PLC in the PLC properties dialog.
7. The Use Comments instruction option determines, by default for a new PLC, whether
program comments (rung comments and annotations) are to include a CMT instruction in
the PLC. CMT instructions are used during upload so that comments in a comment file
can be linked back to the program properly. If this is not set for a PLC then it is not
possible to upload comments, but compiled programs will be smaller since CMT
instructions are not generated.
Note that certain PLC types do not have CMT instructions, and this option will have no
effect for those PLCs.
Note that this option can be enabled / disabled per PLC in the PLC properties dialog.
8. Set the Default Program Type in new PLC option to set the default program type when
creating new projects. The program type can be one of the following three options:
Ladder, ST, or SFC.
9. Set the Automatically Transfer Program to Simulator option to allow program to be
transferred automatically after on-line to the Simulator.
10. Set the Continuous Step Interval option to set the time for continuous step execution of
individual steps by the Simulator. The setting range is 0 to 1000 × 100 ms (i.e., 0.0 to
100.0 s) and the default is 500 ms (i.e., 0.5 s).
11. Select the OK pushbutton to apply the settings and close the dialog. Select the Apply
pushbutton to change the settings but remain in the dialog. Select the Cancel pushbutton
to abort the operation.
1. Select the Symbols tab within the Options dialog.
2. Check the Confirm changes in linked global symbols setting to ensure a confirmation
dialog is displayed before changes are applied to global symbols.
3. Check the Paste rungs to another PLC with unaddressed symbols option to allow rungs
to paste to another program with symbols unaddressed. The symbols will need to be
addressed after copying to another program.
4. Select the OK pushbutton to apply the settings and close the dialog. Select the Apply
pushbutton to change the settings but remain in the dialog. Select the Cancel pushbutton
to abort the operation.
