Description
S, W
The strategy field can be used to identify comprising blocks.
This data is not controlled or used by the block.
S, W
Identification number of the plant component. This information
can be used by the control computer, e.g., to sort alarms. Valid
values are 1 ... 65536.
S, W
Displays the current, permitted standard mode and the target
mode of the block. The target mode can be set to the values
"Auto" or "Out of Service".
Default: Auto
•
Out of service: When actual block mode is OOS
•
Block configuration error:
- Turn_On value of an on/off controller is lower than
Turn_Off value
- Maintenance Required or Out of Specification limits of
temperature, humidity, or frequency inputs not consistent
- On/off controller has input temperature difference and dif-
ferent units are selected for temperature input 1 and 2
•
Other: If XD_ERROR is not zero
•
Sensor failure detected: If any bit in BINARY_ERRORS or
ANALOG_ERRORS is set
This parameter is used to signal to the PCS that a parameter
marked with "S" was overwritten provided that the PCS sup-
ports alarm messages.
This parameter is used to signal to the PCS diagnostic mes-
sages displayed in BLOCK_ERR, provided that the PCS sup-
ports alarm messages.
