8-7. Special Data Registers

• Special data registers are used as a memory area and each data is composed of 16 bits.

• The self-diagnostic error code is stored in DT9000 when a self-diagnostic
error occurs.
• One shift-out hexadecimal digit is stored in hexadecimal digit position 0 (bit

Programming Manual.
• Divided remainder is stored in DT9015 when an
instruction is executed.
• Lower 16-bit of divided remainder are stored in DT9015 when an

instructions in the FP-M/FP1 Programming Manual.
• Higher 16-bit of divided remainder is stored in DT9016 when an

or
F33 (D%)
• Refer to the
Programming Manual.
• An operation error address is stored in DT9017 and held when an
operation error is detected.
• The address of the latest operation error is stored in DT9018 when an
operation error is detected.
• The stored data in DT9019 is increased by one every 2.5 ms.
This can be used to determine the elapsed time of some procedures by
calculating the time differences.
• Current scan time is stored in DT9022.
Scan time is calculated using the formula:
Scan time (ms) = data × 0.1 (ms)
• Minimum scan time is stored in DT9023.
Scan time is calculated using the formula:
Scan time (ms) = data × 0.1 (ms)
• Maximum scan time is stored in DT9024.
Scan time is calculated using the formula:
Scan time (ms) = data × 0.1 (ms)
