Idx Parameter Data Type Size Storage Description / Range / Selections / Notes
17 FEATURES R S B_STR 2 S Used to show supported resource block options
18 FEATURES_SEL RW S B_STR 2 S
Used to select resource block options. For the 266 PdP they are:
Bit 1 Reports Supported
Bit 2 Fault State Supported
Bit 3 SW Write Lock Supported
Bit 4 HW Write Lock Supported
Bit 10 Multi-bit Alarm (Bit-Alarm) Support
19 CYCLE_TYPE R S B_STR 2 S Identifies the block execution methods for this resource
20 CYCLE_SEL RW S B_STR 2 S
Bit 1 Scheduled Used to select the block execution methods for this resource.
Bit 2 Completion of block execution
21 MIN_CYCLE_T R S U32 4 S Time duration of the shorted cycle interval of which the resource is capable.
22 MEMORY_SIZE R S U16 2 S Available configuration memory in the empty resource. To be checked before attempting a download
23 NV_CYCLE_TIME R S U32 4 S
Minimum time interval for writing copies of NV parameters to non-volatile memory. Zero means it will be never automatically
copied.
24 FREE_SPACE R S FLT 4 D Percent of memory available for further configuration. Zero in a preconfigured device
25 FREE_TIME R S FLT 4 D Percent of the block processing time that is free to process additional blocks.
26 SHED_RCAS RW S U32 4 S Time duration at which to give up on computer writes to function block Rcas locations. Shed from Rcas shall never happen when
Shed_Rcas = 0
27 SHED_ROUT RW S U32 4 S Time duration at which to give up on computer writes to function block Rout locations. Shed from Rout shall never happen when
Shed_Rout = 0
28 FAULT_STATE R S U8 1 N Fault State
29 SET_FSTATE RW S U8 1 D Set Fault State
30 CLR_FSTATE RW S U8 1 D Clear Fault State
31 MAX_NOTIFY R S U8 1 S Maximum number of unconfirmed alert notify messages possible
32 LIM_NOTIFY RW S U8 1 S Maximum number of unconfirmed alert notify messages allowed
33 CONFIRM_TIME RW S U32 4 S The min time between retries of alert report. Retries shall not happen when Confirm_Time = 0
34 WRITE_LOCK RW S U8 1 S
1 Unlocked (default),
2 Locked If set, no writes are allowed except to clear Write_Lock. Block inputs will continue to
be updated
35 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
36 BLOCK_ALM RW R DS-72 13 D
The block alarm is used for all configuration, hardware, connection failure or system problems in the block. The cause of the alert
is entered in the subcode field. The first alert to become active will set the Active Status in the status parameter. As soon as the
Unreported status is cleared by the alert reporting task, another block alert may be reported without clearing the Active Status, if
the subcode has changed
37 ALARM_SUM RW R DS-74 8 mix The alert status associated to the function block
38 ACK_OPTION RW S B_STR 2 S
0 Auto Ack Disabled (default)
Selection of whether alarms associated the function block will be automatically
acknowledged
1 Auto Ack Enabled
39 WRITE_PRI RW S U8 1 S Priority of the alarm generated by clearing the write_lock
40 WRITE_ALM RW R DS-72 13 D This alert is generated if the write_lock parameter is cleared
41 ITK_VER R S U16 2 S
Major revision number of the Interoperability test case used in certifying this device as interoperable. See the ITK version used for
the 266 PdP registration from www.fieldbus.org
