Chapter 2 Devices column indicates that it can read and write the data. • The “–” indicates that the status of the special data register does not make any change. • The “#” indicates that the system is set according to the status of the PLC, and you can read the setting. Refer to the • The “Y” in the column latched means it is latched, the “N” means it is non-latched; and “H” means it follows the settings in HWCONFIG. During execution, you can edit programs in the PLC , but the settings in the HWCONFIG do not change. related manual for more information.
