Supplementary Descriptions of the Special Data Registers
■
D8000: Quantity of Inputs
The number of FC6A Series MicroSmart inputs is written to this register.
The total number of inputs for the CPU module and the expansion modules is written to this register.
■
D8001: Quantity of Outputs
The number of FC6A Series MicroSmart outputs is written to this register.
The total number of outputs for the CPU module and the expansion modules is written to this register.
■
D8002: CPU Module Type Information
CPU module type information is written this register.
0 (00h): 16-I/O type
1 (01h): 24-I/O type
2 (02h): 40-I/O type (All-in-One Type)
18 (12h): 40-I/O type (CAN J1939 All-in-One Type)
■
D8005: General Error Code
FC6A Series MicroSmart general error information is written to this register. When a general error occurs, the bit corresponding
to the error occurred turns on. The general error and user program execution error can be cleared by writing "1" to the most
significant bit of D8005. For details on general error codes, see "General Error Codes" on page 13-3.
■
D8006: User Program Execution Error Code
FC6A Series MicroSmartuser program execution error information is written to this register. When a user program execution
error occurs, the error code corresponding to the error that occurred is written to this register. For details on user program
execution errors, see "User Program Execution Error" on page 13-6.
■
D8008 to D8021: Calendar/Clock Data
D8008 through D8021 are used for reading calendar/clock data from the internal clock and for writing calendar/clock data to the
internal clock. For details on the calendar/clock data, see "Clock Function" on page 5-55.
■
D8022 to D8025: Scan Time Data
D8022 through D8025 are special data registers for checking the scan time and configuring the constant scan time. For details
on the scan time, see "Constant Scan Time" on page 5-53.
■
D8026: Communication Mode Information (Port 1 to 3)
This register indicates communication mode information for Port 1 to Port 3.
The allocation of communication ports in the device (bit assignment) is as follows.
