Description
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 TRUE, 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 set to TRUE, the Disturbed Bus error indicates that distorted mes-
sages 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 set to TRUE, 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 set to TRUE, the Hardware Error indicates that an error has occurred
on the bus, e.g. message exceeding 256 bytes, broken messages, faulty
bus timing, or devices beyond the HSA have been detected. The Master
Unit has switched to OFFLINE.
When set to TRUE, it indicates that two switches in the CIO switch word
(see section 4-2-1 Software Switches (*_SwCmd)) were set simultaneously.
The Parameter set error indicates if an error has been detected in the con-
tents 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
(see section 4-2-3 Unit Status (*_UnitSta)).
A Master Error indicates that a new error has been set in the Master Errors
word (see 4-2-5 Master Errors (*_MstrErrSta)).
An error has occurred when storing the configuration to non-volatile mem-
ory.
An error has occurred when loading the configuration from non-volatile
memory.
When set to TRUE, this indicates that a transfer from Memory Card to the
Unit has failed. The Unit must be re-configured.
When set to TRUE, 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 set to TRUE, it indicates that new slave diagnostics have been
received.
When set to TRUE, it indicates that all slaves are in data exchange with the
Master Unit.
