13.4.1 System Registers
What is the system register area
System registers are used to set values (parameters) which determine operation
ranges and functions used. Set values based on the use and specifications of your
program. There is no need to set system registers for functions which will not be used.
Type of system registers
Hold/non-hold type setting (System registers 5 to 8, 10, 12 and 14)
The values for the timer and counter can be specified by using system register no. 5
to specify the first number of the counter. System registers no. 6 to no. 8, no. 10, no.
12, and no. 14 are used to specify the area to be held when a battery is used.
Operation mode setting on error (System registers 4, 20,23 and 26)
Set the operation mode when errors such as battery error, duplicated use of output, I/O
verification error and operation error occur.
Time settings (System registers 31 to 34)
Set time-out error detection time and the constant scan time.
MEWNET-W0 PLC link settings (System registers 40 to 45, and 47)
These settings are for using link relays and link registers for MEWNET-W0 PLC link
communication.
Note that the default value setting is “no PLC link communication”
Input settings (System register 400 to 403)
When using the high-speed counter function, pulse catch function or interrupt function,
set the operation mode and the input number to be used as a exclusive input.
Tool and COM. ports communication settings (System registers 410 to 419)
Set these registers when the tool port, COM.1 and COM.2 ports are to be used for
computer link, general communication, PLC link and modem communication.
Note that the default value setting is “Computer link” mode.
Checking and changing the set value of system register
1. Set the control unit in the “PROG” mode.
2. Select “PLC Configuration” under “Option” on the menu bar.
3. When the function for which settings 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, click on the “OK” button.
