To check the error code in a controller, use a 0x0001 command (status / error) in command mode to read
the error code.

8-2 Communication errors

If an error occurs, set RY[7A]: clear error request (*1) to clear the error state.
If the error does not clear when RY[7A]: clear error request (*1) is set and RX[7B]: remote ready
flag (*2) does not set, check the state of the connection with the communication unit and then
restart.
RX[7B] (*2)
Check remote ready flag
RX[7A] (*3)
Error status flag
RX[6F]
Communication unit error
flag
RY[7A] (*1)
Set an error clear request
1.
Check that RX[7B]: remote ready flag (*2) is cleared and RX[7A]: error flag (*3) is set.
RX[6F]: communication unit error flag indicates whether or not an error state is due to a
problem in the communication unit. If the problem is in the communication unit, RX[6F]: com-
munication unit error flag is set.
2.
Set RY[7A]: clear error request (*1). This operation causes the communication unit to clear
RX[7A] (*3): error status flag and sets RX[7B] (*2): remote ready flag. At this time, if RX[6F]:
communication unit error flag is set, RX[6F]: communication unit error flag will also be
cleared. (*4)
If RX[7B]: remote ready flag is not set when the above operation is performed, this indicates
that the error was caused by a problem that does not allow recovery by operation. In this
event, remove the cause of the error and cycle the power OFF - ON.
3.
Clear RY[7A]: clear error request (*1).
*1: The bit position depends on the operation mode.
CC-Link mode 1: RY[7A], CC-Link mode 2: RY[17A] CC-Link, mode 3: RY[1BA]
*2: The bit position depends on the operation mode.
CC-Link mode 1: RX[7B], CC-Link mode 2: RX[17B], CC-Link mode 3: RX[1BB]
*3: The bit position depends on the operation mode.
CC-Link mode 1: RX[7A], CC-Link mode 2: RX[17A], CC-Link mode 3: RX[1BA]
*4: You can enter error mode and check the error code.
For details on error mode, refer to "4-9 Error mode".
