Description
On: Normal operation
On: PLC to PLC network
On: Remote I/O network (always turned off in the RJ71LP21-25)
On: Multiplex transmission in progress
On: Switch setting error (always turned off in the RJ71LP21-25)
On: Duplicated station number or control station on the same network
On: Parameter error
On: Control station is set.
Off: Normal station is set.
On: Sub-control station is set.
On: Testing
On: Data link in progress (cyclic transmission being performed)
On: Baton pass in progress (joined in the network)
Flashing: Testing
On: A CRC error has occurred on the forward loop side.
(An error was detected in checking code for receive data)
On: An overrun error has occurred on the forward loop side.
(An error has occurred due to a delayed processing of receive data.)
On: An abort error has occurred on the forward loop side.
(An error has occurred when the value "1" is continuously received over the specified number of times or the receive
data length is short.)
On: A timeout error has occurred on the forward loop side.
(An error has occurred when the data link monitoring timer operated.)
On: An error of reception of 2K bytes or more has occurred on the forward loop side.
(An error has occurred due to receiving abnormal data whose size is 2K bytes or more.)
On: An under-error has occurred on the forward loop side.
(An error has occurred when the value "1" is continuously received over the specified number of times or the receive
data length is short.)
On: A faulty station exists on the forward loop side.
(An error has occurred due to the loop being faulty.)
On: A CRC error has occurred on the reverse loop side.
(An error was detected in checking code for receive data)
On: An overrun error has occurred on the reverse loop side.
(An error has occurred due to a delayed processing of receive data.)
On: An abort error has occurred on the reverse loop side.
(An error has occurred due to 1 being continuously received over the specified number of times or due to the receive
data length being short.)
On: A timeout error has occurred on the reverse loop side.
(An error has occurred when the data link monitoring timer operated.)
On: An error of reception of 2K bytes or more has occurred on the reverse loop side.
(An error has occurred due to receiving abnormal data whose size is 2K bytes or more.)
On: An under-error has occurred on the reverse loop side.
(An error has occurred due to the internal processing of send data not being performed at the specified intervals.)
On: A faulty station exists on the reverse loop side.
(An error has occurred due to the loop being faulty.)
