Description
ALERT_KEY AUTO - MAN -
OOS - CAS -
RCAS
Entry of the identification number of the plant unit.
This information can be used by the fieldbus host system for
sorting alarms and events.
User input:
1...255
Factory setting:
0
BLOCK_ALM AUTO - MAN -
OOS - CAS -
RCAS
Displays the current block status with information on pending
configuration, hardware or system errors, including details of the
alarm time (date, time) when the error occurred.
The block alarm is triggered in the event of the following block
errors:
• SIMULATION ACTIVE
• INPUT FAILURE
• OUTPUT FAILURE
• READBACK FAILURE
• OUT OF SERVICE
• BLOCK CONFIG ERROR
BKCAL_
OUT_D
read only Displays the discrete output value and output status transferred in
the case of cascade control to the BKCAL_IN_D input of the
upstream function block.
BLOCK_ERR read only Displays the active block error.
Display:
SIMULATION ACTIVE
Simulation in the "SIMULATE_D" parameter group of the Discrete
Output Block is active.
INPUT FAILURE
Input fault. The input value of the upstream function block has a
status of BAD.
OUTPUT FAILURE
Fault in Transducer Block.
READBACK FAILURE
A fault in the hardware used by the READBACK_D parameter.
OUT OF SERVICE
The block has the status "Out of Service".
BLOCK CONFIG ERROR
• An operating switchover is not possible, since the value of the
Period of Execution time = 0.
• A switchover to the RCAS operating mode is not possible since
"Uninitialized" was selected in the SHED_OPT parameter.
