Standard and
Retentive
memory
management
The IEC 1131 programming tools allow to declare retentive variables using a spe-
cific syntax. These variables are saved and load from the retained memory which
has a 32kB size (for security reasons, the memory is duplicated and refreshed
during runtime operations). Differently from this automatic mechanism, it is possi-
ble to specify, during the boot-up configuration session, the amount of retained
variables to be used in the percentage area.
The standard memory locations usable as retentive variables are accessible as
registers, up to the maximum amount normally available for each Modbus agent
(Slave 1 and Slave 2) and up to 16 kB in the marker area.
In particular, the range of registers available as retentive are:
Modbus Slave 1 : %MW1128.0... %MW9320.0
Modbus Slave 2 : %MW10128.0... %MW18320.0
Marker Area : %MB22000.0... %MB38363.0
