12-4
(10) Input time constant settings (FP1/FP-M System registers 404 to 407)
Changing the input signal width to be loaded enables to prevent the malfunctions caused by chattering
or noises.
(11) Number of temperature input averaging process settings (System register 409)
The number of averaging times can be set in order to even out the variation in the input thermocouple
values. For normal use it, set the number of times to t least twenty. For default value “0”, the number of
average processing times is 20.
(12) Tool and COM. ports communication settings (System registers 410 to 421)
Set these registers when the Tool port,and COM1 and COM2 ports are to be used for computer link,
general-purpose serial communication, PC(PLC) link, and modem communication.Note that the default
setting is computer link mode.
Checking and changing the set value of system register
If you are going to use a value which is already set(the value which appears when read),
there is no need write it again.
Using programming tool software
Produce:
1. Set the control unit in the PROG mode.
2.Option ->PLC Configuration
3.When the function for which setting are to be entered is selected in the PLC Configuration
dialog box,the value and setting status for the selected system register are displayed.
To change the value and setting status,write in the new value and /or select the setting status.
4.To register these settings,choose OK
Using FP programmer II
Produce:
The usable PLCs depend on the models.
Check the usage restrictions of the programming tool.
1. Set the mode selector of the CPU to PROG.
2. Press the keys on the FP programmer II, as shown below.
3. Specify the register number (e.g. No. 26) for the parameter to be set and read the parameter.
The value set in the selected register (e.g. No. 26) will be displayed.
4. To change the set value, press the <CLR (clear)> key and write the new value as indicated in the
system register table using decimal (K) or hexadecimal (H) constant.
Precautions for system register setting
-System register settings are effective from the time they are set.
However, input settings,tool port,COM port,and modem connection settings become effective when the
mode is changed from PROG. to RUN. With regard to the modem connection setting, when the power is
turned off and on or when the mode is changed from PROG. to RUN, the controller sends a command to
the modem which enables it for reception.
-When the initialized operation is performed, all set system register values (parameters) will be initialized.
