Operation Errors
8.4.1
Outline of Operation Errors
An operation error is a condition in which operation is impossible when a high-level
instruction is executed.
When an operation error occurs, the ERROR/ALARM LED on the FP0 control unit will
blink and the operation error flags (R9007 and R9008) will turn on.
The operation error code “E45” is set at special data register DT9000.
The error address is stored in special data registers DT9017 and DT9018.
Types of Operation Error
Address error
The memory address (number) specified by index modification is outside the area which
can be used
BCD data error
Operation is attempted on non
−
BCD data when an instruction handling BCD is
executed, or BCD conversion is attempted on data which is not within the possible
conversion range.
Parameter error
In an instruction requiring the specification of control data, the specified data is outside
the possible range.
Over area error
The data manipulated by a block instruction exceeds the memory range.
8.4.2
Operation Mode When an Operation Error Occurs
Normally, the operation stops when an operation error occurs.
However, when you set system register 26 to “continuation” (KI), the FP0 control unit
operates even if an operation error occurs.
