The content of the global registers "Gxx" and "GLx" is backed up in case
control voltage fails, i.e. the register contents are stored in non-volatile
form so that the parameter contents do not get lost in case voltage fails.
The global registers G0 ... G15 or GL0 can therefore be used for the
following applications:
• parameterization of PLC functions or function blocks
• communication with the external control unit via the master
communication
• use as non-volatile (permanent) memory for the MLD-S because the
contents are retained in case voltage fails
In addition there are the two global registers "P-0-1387, PLC Global
Register AT0" and "P-0-1387, PLC Global Register AT1" which are
available as freely usable text parameters with a maximum of 255
characters plus closing "0" character.
Note: The two global text parameters of the PLC are not stored.
The global registers (AT0 and AT1) can therefore be used for the
following applications:
• communication with higher-level control unit or HMI
• definition of freely definable diagnostic message texts
