Things to Consider when Storing to the PLC from the Programmer
Use the Store function to copy program logic, configuration data, and /or reference
tables from the programmer to the PLC. The Store function copies the program, which
remains unchanged in the programmer. If the PLC program name is not the same as the
folder name, the Store function clears the program from the PLC. The selected data is
then stored from the new program folder.
If the function is password-protected in the PLC, you must know the password in order
to use this function.
Note
In the configuration software, only the configuration may be stored. No
operations on program logic or tables may be performed.
In RUN MODE STORE, you can only store program logic under these conditions:
1. Only blocks that have been changed are stored.
2. The old program executes until the blocks are completely stored, then the new
program begins executing in a “bumpless” manner.
3. The data sizes for %L and %P are based on the highest references used in each
block, regardless of whether the block is called. %L and %P data is increased as these
references are programmed. If a reference to %L or %P) is deleted, the new smaller
size is calculated when the folder is selected.
4. Interrupt declaration changes cannot be made.
5. There must be enough PLC memory to store both old and new program blocks.
6. Timed or event-triggered programs cannot be added or deleted.
7. Control information (scheduling mode, I/O specification, etc...) for programs cannot
be modified.
In STOP MODE STORE, the following can be performed:
1. You can store program logic, configuration data, and/or reference tables from the
programmer to the PLC.
2. If you choose to store logic only and the PLC program name is different than the
program name in the folder, the current logic in the PLC will be cleared and replaced
by the new logic in the current folder. The current configuration data and reference
tables in the PLC are left intact.
3. If you choose to store logic and configuration data and./or reference tables, the logic,
configuration data, and reference tables in the PLC are cleared, and the new data is
stored from the programmer to the PLC.
