Flag conditions
・
Error flag (R9007) (R9008):
- It turns on, when the specified address using the index modifier exceeds a limit.
- It turns on, when the MCU unit does not exist in the slot No. specified by [S].
- It turns on, when the communication port specified by [S] does not exist.
- It turns on, when the data device specified by [D1] exceeds the area.
- It turns on, when the data device specified by [D2] exceeds the area.
- It turns on, when [D1] > [D2].
