7.1 Modbus Register Address Aliasing (continued)
Reading back from the same registers it can be seen all the modified data. Note that the last “Start
Saving Level” datum has not changed, since 21320 is a Read only register.
Once set the addresses can be saved in none volatile memory if required. However, given that this
a programmable feature, best practice would be to program the aliases at the start of a PLC
session. Saving can be done by either using the “Save Parameter” button in the Advanced section
of the keypad, or by setting appropriate Modbus register (62144). The alias being processed may
be cleared by setting each Alias Register Address to 0 or by performing a factory default.
