■
D8037: Number of Connected Expansion Modules
The number of expansion modules connected to the CPU module (I/O modules, PID modules, and communication 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 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)
The analog volume value is converted to a digital value and written to this register. For details, see Chapter 5 "Analog
Potentiometer" in the "FC6A Series MICROSmart User’s Manual".
■
D8058: Built-in Analog Input (AI1)
The analog input's analog value (0 to 10V DC) is converted to a digital value and written to this register. For details, see
Chapter 5 "Analog Voltage Input" in the "FC6A Series MICROSmart User’s Manual".
■
D8059: Analog Input Status AI0
The analog volume's analog input status is written to this register. For details, see Chapter 5 "Analog Potentiometer" in the
"FC6A Series MICROSmart User’s Manual".
■
D8060: Analog Input Status AI1
The analog input's analog input status is written to this register. For details, see Chapter 5 "Analog Voltage Input" in the "FC6A
Series MICROSmart User’s Manual".
■
D8067: Backlight ON Time
The backlight on time for the HMI module is written to this register. The backlight on time can be set by modifying the value of
D8067 in a range between 1 and 65,535 s. When D8067 is 0 s, the backlight is always on. The backlight on time can also be
changed with the HMI environment settings. For details, see Chapter 7 "Setting the LCD Backlight ON Time" in the "FC6A Series
MICROSmart User’s Manual".
■
D8069 to D8099: Slave (1 to 31) Communication Status/Error
Special data registers used in data link communication. For details, see Chapter 7 "Master Station" in the "FC6A Series
MICROSmart Communication Manual".
■
D8040 to D8045, D8100, D8102, D8103, D8735 to D8758: Slave Number (Port 1 to 33)
The slave number is written to these registers when the Port 1 to 33 communication mode is maintenance communication,
Modbus RTU slave, or data link communication. The slave number can be changed by changing the value of the corresponding
device in
Function Area Settings .
For details on communication modes, see the following in the "FC6A Series MICROSmart Communication Manual".
