RID16 Operation via FOUNDATION™ Fieldbus
Hauser 43
11.2.1 Selecting the operating mode
The operating mode is set by means of the MODE_BLK parameter group. The Resource Block
supports the following operating modes:
• AUTO (automatic mode)
• OOS (out of service)
!
Note!
The 'Out of Service' (OOS) operating mode is also displayed by means of the BLOCK_ERR
parameter. In the OOS operating mode, all write parameters can be accessed without restriction if
write protection has not been enabled.
11.2.2 Block status
The current operating status of the Resource Block is displayed in the RS_STATE parameter.
The Resource Block can assume the following states:
• STANDBY
The Resource Block is in the OOS operating mode. It is not possible to execute the remaining
function blocks.
• ONLINE LINKING
The configured connections between the function blocks have not yet been established.
• ONLINE
Normal operating status, the Resource Block is in the AUTO operating mode.
The configured connections between the function blocks have been established.
11.2.3 Write protection
DIP switches inside the housing allow device parameter write protection to be disabled or enabled.
The WRITE_LOCK parameter shows the status of the hardware write protection. The following
statuses are possible:
• LOCKED =
The device data cannot be altered via the FOUNDATION™ Fieldbus interface.
• NOT LOCKED =
The device data can be altered via the FOUNDATION™ Fieldbus interface.
11.2.4 Alarm detection and processing
Process alarms provide information on certain block states and events.
The status of the process alarms is communicated to the fieldbus host system by means of the
BLOCK_ALM parameter. The ACK_OPTION parameter allows you to specify whether an alarm has
to be acknowledged by means of the fieldbus host system. The following process alarms are
generated by the Resource Block:
Block process alarms
The following block process alarms of the Resource Block are displayed by means of the
BLOCK_ALM parameter:
• OUT OF SERVICE
Write protection process alarm
If the write protection is disabled, the alarm priority specified in the WRITE_PRI parameter is
checked before the status change is relayed to the fieldbus host system. The alarm priority specifies
the behavior in the event of an active write protection alarm WRITE_ALM.
!
Note!
If the option of a process alarm was
not activated in the ACK_OPTION parameter, this process
alarm must only be acknowledged in the BLOCK_ALM parameter.
