10.3 Operation Errors

10.3.1 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 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 DT90000.
-
The error address is stored in special data registers DT90017 and DT90018.
-
Types of operation error
1. Address error
The memory address (number) specified by index modification is outside the area which can be used.
2. 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.
3. Parameter error
In an instruction requiring the specification of control data, the specified data is outside the possible
range.
4. Over area error
The data manipulated by a block instruction exceeds the memory range.
10.3.2 Operation Mode When an Operation Error Occurs
Normally, the operation stops when an operation error occurs.
-
When you set system register 26 to "continuation", the control unit operates even if an operation error
-
occurs.
