Default System Tags
Note: Please do not attempt to modify read only system tags in the ladder. This could affect the functionality of
the product.
System Registers / Coils:
Register / Coil Tag Name Read / Write Description
SW0003_14 COM1 Status Read Only 0 = Communication Error; 1= Communicating
with PLC
SW0003_15 COM2 Status Read Only 0 = Communication Error; 1= Communicating
with PLC
S0000 Carry Bit Read/Write Overflow indication in math operations of ladder
and also used in rotate with carry instruction.
SW0010 RTC Day of Month Read only RTC day in integer format
SW0011 RTC Month Read only RTC month in integer format
SW0012 RTC Year Read only RTC year in integer format
SW0013 RTC Hour Read only RTC hour in integer format
