6.6 PLC Data

6.6.1.1 Sequence Program Details

The following details for created data can be saved as program data.
Saved details
Program (ladder) circuits
Statements
Notes
(*1) Integrated statements, notes, and peripheral statements
Integrated type Integrated types can be saved in the NC. Note that the program data takes up a large amount of mem-
ory when stored in the NC.
Peripheral types Peripheral types are deleted when saved to the NC.
For this reason, when using peripheral statements or notes, they must be managed as GX Developer/
GX Works2 projects.
Peripheral types are also stored to symbolic information when using project with labels or structured
project with GX Works2.
For this reason, when symbolic information is stored, it is displayed on PLC on-board.

This is data used to edit and monitor the user PLC with following ladder dia-
grams.
Statements are text strings added to each program ladder block to make it easier
to understand the flow of the entire program. Statements include integrated
statements that can be stored in the NC and peripheral statements that cannot
be stored in the NC.(*1)
Similar to statements, notes are text strings added to each coil and function in-
struction in the program ladder to make it easier to understand the flow of the en-
tire program. Notes include integrated notes that can be stored in the NC and
peripheral notes that cannot be stored in the NC.(*1)
PLC alarm messages displayed on the NC.
PLC operator messages displayed on the NC.
Text strings used to name PLC switches.
PLC comment text strings displayed on the NC.
Text string data added to each device. Programs are easier to understand when com-
ments are assigned to the devices.(*1)
These text strings are displayed in place of the device name. These text strings make
it easier to visually distinguish between programs.(*2)
These are execution sequences for multiple programs (ladders).
These are numbers placed at the beginning of common pointers.
