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:
11.2.3 Write protection and simulation
The write protection of the device parameters and the simulation in the Analog Input and Discrete
Output Function Block can be enabled or disabled via DIP switches on the FOUNDATION Fieldbus
I/O board or the amplifier boardPage 35.
The WRITE_LOCK parameter shows the status of the hardware write protection. The following
statuses are possible:
The BLOCK_ERR parameter indicates whether simulation in the Analog Input and Discrete Output
Function Block is possible.
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:
– STANDBY The Resource Block is in the OOS operating mode. The other
blocks cannot be executed.
– 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.
– 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.
– Simulation active = Simulation possible in the Analog Input Function Block via the
SIMULATE parameter and in the Discrete Output Function Block
via the SIMULATE_D parameter.
–OUT OF SERVICE
– SIMULATE ACTIVE
