■
D8032 to D8035, D8214, D8215: Interrupt Input Jump Destination Label No.
Jump destination label numbers for interrupt inputs are written to these registers. When using interrupt inputs, write the label
number that corresponds to the special data register that has been allocated to the interrupt input. For details on interrupt
inputs, see "Interrupt Input" on page 5-33.
D8032 = I1
D8033 = I3
D8034 = I4
D8035 = I6
D8214 = I7
D8215 = I0
■
D8036: Timer Interrupt Jump Destination Label No.
The jump destination label number when the timer interrupt occurs is written to this register. When using the timer interrupt,
store the corresponding label number.
For details on the timer interrupt, see "Timer Interrupt" on page 5-42.
■
D8037: Number of Connected Expansion Modules
The number of expansion modules connected to the CPU module (expansion I/O modules and functional modules) is written to
this register.
■
D8052: J1939 Communication Error Code
When an error occurs in J1939 communication, the error code is written to this register. For details on J1939 communication
error codes, see Chapter 8 "J1939 Communication Error Code (D8052)" in the "FC6A Series MicroSmart All-in-One Type
Communication Manual".
■
D8056: Battery Voltage
The measurement result of the backup battery voltage is written to this register in 1 mV units.
0: Measurement error
■
D8057: Analog Volume (AI0)
