Chapter 9 Parameter
9-6
i. Used to specify the start address of DO (Digital Output) memory area to read through MODBUS, where
the value should be specified in Word unit.
j. Used to specify the start address of AI (Analog Input) memory area to read through MODBUS, where the
value should be specified in Word unit.
k. Used to specify the start address of AO (Analog Output) memory area to read through MODBUS, where
the value should be specified in Word unit.
Notes Restart Mode
Restart mode is set to determine how to initialize variable and system and start RUN mode operation when
starting RUN mode operation by turning it on again or mode conversion and there are two modes; cold and
warm. The execution conditions of each restart mode are as follows.
- Cold Restart
a) It is executed when setting the restart mode of parameter as cold restart.
b) First of all, it clears every data but variables of which initial value is set to ‘0’.
c) Even though the parameter is set to warm restart mode, it starts in cold restart mode when it is
executed just after the program is changed.
d) Pressing RESET switch during operation (same with online reset instruction), starts in the cold restart
mode, regardless of the restart mode set in the parameter.
- Warm Restart
a) It is executed when setting the restart mode of parameter as warm restart.
b) The data set to remain the previous value remain the previous value while the data set only with the
initial value are set with the initial values. Other data are cleared to ‘0’.
c) If data is abnormal although the parameter is set in the warm restart (data preservation against
interruption is not available), it is executed in the cold restart mode.
