The User Program
Section 2-3
When the command is executed and the address is found to have been over-
written for the number of operations set by the user, the Data Carrier warning
flag will be turned ON.
Command Processing:
Overwriting operation management area consists of three bytes from the first
address, from which the appropriate number is subtracted. If the value set in
this area is smaller than 0, the Data Carrier warning flag will be turned ON. If
the data in the management area is already 0, the value in the overwriting
operation management area will not be renewed.
When using a DC with the number of overwriting operations set to 300,000,
make the settings as shown below.
