Operation via FOUNDATION Fieldbus TM
iTEMP TMT85
68 Hauser
alarm priority specifies the action taken when the write protection alarm WRITE_ALM is
active.
If the option of a process alarm has not been activated in the ACK_OPTION
parameter, this process alarm only has to be acknowledged in the BLOCK_ALM
parameter.
14.2.5 Resource Block FF parameters
The following table shows all the specified FOUNDATION Fieldbus TM parameters of the
Resource Block.

Parameter Write access with
operating mode
(MODE_BLK) Description
38 Acknowledge Option
(ACK_OPTION) AUTO - OOS This parameter is used to specify whether a process alarm must be
acknowledged by the fieldbus host system when the alarm is detected. If the
option is activated, the process alarm is acknowledged automatically.
Factory setting:
The option is not activated for any alarm. The alarms must be acknowledged.
37 Alarm Summary
(ALARM_SUM) AUTO - OOS Displays the current status of the process alarms in the Resource Block.

The process alarms can also be disabled in this parameter group.
4 Alert Key (ALERT_KEY) AUTO - OOS Use this function to enter the identification number of the plant unit. This
information can be used by the fieldbus host system to sort alarms and
events.
User input:
1 to 255
Factory setting:
0
36 Block Alarm (BLOCK_ALM) AUTO - OOS Displays the current block condition with information on pending
configuration, hardware or system errors, including information on the date
and time when the error occurred.
The block alarm is triggered by the following block errors:
• SIMULATE ACTIVE
• OUT OF SERVICE

If the alarm option is not activated in the ACK_OPTION parameter, the
alarm can only be acknowledged via this parameter.
6 Block Error (BLOCK_ERR) Read only Displays the active block errors.
Display:
SIMULATE ACTIVE
Simulation in the Analog Input function block is possible via the SIMULATE
parameter (see also the settings for HW write protection in →  26).
OUT OF SERVICE
The block is in the “Out of Service” mode.
75 Block Error Description 1
(BLOCK_ERR_DESC_1) Read only Displays additional information to troubleshoot a block error:
• Simulation permitted: Simulation is permitted with the activated
simulation switch
• Failsafe active: Failsafe mechanism in an AI block is active
42 Capability Level (CAPABILITY_)
LEVEL Read only Indicates the capability level which the device supports.
30 Clear Fault State (CLR_FSTATE) AUTO - OOS The fault state of the Analog Output and Discrete Output function blocks can
be manually disabled via this parameter.
43 Compatibility Revision
(COMPATIBILITY_REV) Read only Indicates the previous device revision with which the device is compatible.
