2.3 Write protection and simulation
Write protection of the device parameters and simulation in the Analog Input and
Discrete Output function block can be enabled or disabled via jumpers on the
FOUNDATION Fieldbus I/O board, (see Operating Instructions for PROline Prosonic
Flow 93 FOUNDATION Fieldbus, BA078D/06/en, Section 5.4).
The WRITE_LOCK parameter (see Page 98) shows the status of the hardware write
protection. The following statuses are possible:
The BLOCK_ERR parameter (see Page 92) indicates whether a simulation is possible
in the Analog Input and Discrete Output function block.
2.4 Alarm detection and processing
Process alarms provide information on particular block statuses and block events.
The status of the process alarms is communicated to the fieldbus host system via the
BLOCK_ALM parameter, (see Page 91). The ACK_OPTION parameter (see Page 91)
specifies whether an alarm must be acknowledged via 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 shown via the
BLOCK_ALM parameter, (see Page 91):
Write protection process alarm
If write protection is disabled on the FOUNDATION Fieldbus I/O board, the alarm priority
specified in the WRITE_PRI parameter (see Page 98) is checked prior to
communicating the change of status to the fieldbus host system. The alarm priority
specifies the action taken in the event of an active write protection alarm WRITE_ALM
(see Page 97).

Note!
• If the option of a process alarm has not been enabled in the ACK_OPTION parameter
(see Page 91) this process alarm must only be acknowledged in the BLOCK_ALM
parameter (see Page 91).
• The ALARM_SUM parameter (see Page 91) shows the current status of all the process
alarms.
– LOCKED = Device data cannot be modified via the FOUNDATION
Fieldbus.
– NOT LOCKED = Device data can be modified via the FOUNDATION
Fieldbus.
– SIMULATION ACTVE = Simulation possible via the SIMULATE parameter in the
Analog Input function block and via the SIMULATE_D
parameter in the Discrete Output function block.
– OUT OF SERVICE
– SIMULATION ACTVE
