Master Unit is in OPERATE mode.
Master Unit is in STOP mode.
Master Unit is in CLEAR mode.
Master Unit is in OFFLINE mode.
When set to ON, it indicates that the Master Unit is in Data Exchange with all its
allocated and enabled slave devices.
Auto-Clear function has been enabled in the downloaded configuration.
The Master Unit contains a valid configuration.
When turned ON, the Disturbed Bus error indicates that distorted messages
have been received by the Unit. This may occur if the network is not properly
terminated or a cable is used, which is too long for the selected baud rate.
When turned ON, the PROFIBUS Protocol Error indicates that an error has
occurred in the protocol handling, e.g. a transmitted token frame could not be
read back. The Master Unit has switched to OFFLINE.
Indicates that a second Master with the same address has been detected on the
Bus. The Master Unit has switched to OFFLINE.
When turned ON, the Hardware Error indicates that an error has occurred on
the bus, e.g. message exceeding 256 bytes, broken messages, faulty bus tim-
ing, or devices beyond the HSA have been detected. The Master Unit has
switched to OFFLINE.
When set to ON, it indicates that two switches in the CIO switch word were set
simultaneously (refer to the CS1/CJ1W-PRM21 Operation Manual,
W409-E2-@).
The Parameter set error indicates if an error has been detected in the contents
of the Parameters set while configuring the PROFIBUS interface, using these
parameters.
A Unit error indicates that a new error has been set in the Unit Status word (refer
to the CS1/CJ1W-PRM21 Operation Manual, W409-E2-@).
A Master Error indicates that a new error has been set in the Master Status 2
word (refer to the CS1/CJ1W-PRM21 Operation Manual, W409-E2-@).
An error has occurred when loading the configuration from non-volatile memory.
When turned ON, this LED indicates that a transfer from Memory Card to the
Unit has failed. The Unit must be re-configured.
When turned ON, it indicates that an error has occurred when writing the Error
Log to the Non-volatile memory.
The Error Log contains new entries, since the last time it was read or cleared.
Configuration Parameters are being transferred to or from the Unit.
When turned ON, it indicates that new slave diagnostics have been received.
When turned ON, it indicates that all slaves are in Data exchange with the Mas-
ter Unit.
