Programming Console Operations Section 4-2
The ON/OFF status of any displayed bit will be shown if the PC is in RUN or
MONITOR mode.
1,2,3... 1. Press the CLR Key to bring up the initial display.
2. Input the address from which the search will begin and press the Down Ar-
row Key. It is not necessary to input leading zeroes.
3. Input the instruction to be found and press the SRCH Key. In this case, the
search is for OUT 01000.
In this case, the next OUT 01000 instruction is at address 200, as shown
below.
4. Press the Down Arrow Key to display the instruction’s operands or press
the SRCH Key to search for the next occurrence of the instruction.
5. The search will continue until an END instruction or the end of Program
Memory is reached. In this case, an END instruction was reached at ad-
dress 397.
4-2-11 Bit Operand Search
This operation is used to find occurrences of the specified operand bit in the
program and is possible in any mode.
The ON/OFF status of any displayed bit will be shown if the PC is in RUN or
MONITOR mode.
1,2,3... 1. Press the CLR Key to bring up the initial display.
2. Input the operand address. It is not necessary to input leading zeroes.
3. Press the SRCH Key to begin the search.
4. Press the SRCH Key to search for the next occurrence of the operand bit.
5. The search will continue until an END instruction or the end of Program
Memory is reached. In this case, an END instruction was reached.
