Remarks:
Changing of a parameter is only possible if the new value is in the allowed range (see descrip-
tion). These registers are non-volatile. For the new settings to become effective a reset
(Power-cycle the EA) is required.
Note the address gap between the board configuration registers and normal operation
registers.
Register # 49001 refers to register holding register address 9000 (2328(hex)).
The Modbus RTU board configuration can be reset to its default values (see Table above) by
triggering a factory reset on the Electric Actuator base-board (see user manual of the Electric
Actuator).
