Status Controlled
by
ON Unit Indicates that the Unit is in OPERATE mode.
In OPERATE mode the PROFIBUS Master Unit will parameterize all
allocated slave devices, and commence I/O Data-Exchange.
OFF Unit Indicates that the Unit is not in OPERATE mode.
ON Unit Indicates that the Unit is in STOP mode.
In STOP mode, the Unit will be ONLINE, connected to the network, but
not communicate with its slave devices.
OFF Unit Indicates that the Unit is not in STOP mode.
ON Unit Indicates that the Unit is in CLEAR mode.
In CLEAR mode the PROFIBUS Master Unit will parameterize all allo-
cated slave devices. If this is accomplished successfully, it will read all
input data of the allocated slave devices, but it will send zeros or empty
output messages to all slave devices.
OFF Unit Indicates that the Unit is not in CLEAR mode.
ON Unit Indicates that the Unit is in OFFLINE mode.
In the OFF-LlNE mode the Unit will be disconnected from the network.
OFF Unit Indicates that the Unit is not in OFFLINE mode.
Unit If set to ON, this bit indicates that the Unit is in Data_Exchange with at
least one allocated and enabled slave device.
Unit If set to OFF, this bit indicates that the Unit is not in Data_Exchange
with at any of the allocated and enabled slave devices.
Unit If set to ON, this bit indicates that the Auto-CLEAR function has been
enabled. In case an error occurs in one of the allocated slave devices
during Data_Exchange, this function forces the Unit to the CLEAR
mode, in which it will force all allocated slave devices to a Fail Safe
mode.
Unit If set to OFF, the Auto-CLEAR function has been disabled. If in this
case an error occurs in an allocated slave device, the PROFIBUS Mas-
ter Unit will continue Data_Exchange with the remaining slave devices.
--- This bit will be set to OFF by the Unit.
Unit If set to ON, this bit indicates that the Unit contains a valid Configura-
tion. With this Configuration it can parameterize the allocated slave
devices and achieve Data_Exchange.
Unit If this bit is set to OFF, the Unit does not contain a valid Configuration or
transfer of a new Configuration is in progress.
--- These bits will be set to OFF by the Unit
