10 MANUFAC_ID Unsigned32 Enumeration;
controlled by FF 0x00014D None RO Manufacturer identification number - used by an
interface device to locate the DD file for the resource
block.
11 DEV_TYPE Unsigned16 Set by mfgr None RO Manufacturer model number associated with the
resource block - used by interface devices to locate the
DD file for the resource block.
12 DEV_REV Unsigned8 Set by mfgr None RO Manufacturer revision number associated with the
resource block - used by an interface device to locate
the DD file for the resource block.
13 DD_REV Unsigned8 Set by mfgr None RO Revision of the DD associated with the resource block -
used by an interface device to locate the DD file for the
resource block.
14 GRANT_DENY DS-70 0 N/A RW Not user configurable.
15 HARD_TYPES Bitstring(2) Set by mfgr N/A RO Not user configurable.
16 RESTART Unsigned8 1: Run,
2: Resource,
3: Defaults,
4: Processor
5: Factory 0 E A Allows a manual restart to be initiated. Several
degrees of restart are possible.
17 FEATURES Bitstring(2) Set by mfgr N/A RO Used to show supported resource block options. See
FEATURES Bits on
page 110 .
18 FEATURE_SEL Bitstring(2) See
FEATURE_SEL
Bits on page 111 0 N/A A Used to select resource block options.
19 CYCLE_TYPE Bitstring(2) Set by mfgr N/A RO Identifies the block execution methods available for
this resource block. This parameter is reserved for
future use. See CYCLE_TYPE Bits on
page 110 .
20 CYCLE_SEL Bitstring(2) See CYCLE_SEL
Bits on page 111 0 N/A A Used to select the block execution method for this
resource block. This parameter is reserved for future
use.
21 MIN_CYCLE_T Unsigned32 Set by mfgr 0 1/32 ms RO Time duration of the shortest cycle interval of which
the resource block is capable.
22 MEMORY_SIZE Unsigned16 Set by mfgr kB RO Available configuration memory in the empty resource.
To be checked before attempting a download. This
parameter is reserved for future use.
23 NV_CYCLE_T Unsigned32 0 1/32 ms RO Interval between writing copies of NV parameters to
nonvolatile memory. Zero means never.
24 FREE_SPACE Float 0 to 100% % RO Percent of memory available for further configuration.
Zero in a preconfigured resource. This parameter is
reserved for future use.
25 FREE_TIME Float 0 to 100% % RO Percent of the block processing time that is free to
process additional blocks. This parameter is reserved
for future use.
26 SHED_RCAS Unsigned32 640000 1/32 ms AUTO Not user configurable.
27 SHED_ROUT Unsigned32 640000 1/32 ms AUTO Not user configurable.
28 FAULT_STATE Unsigned8 0: Uninitialized
1: Clear
2: Active 0 E RO Condition set by loss of communication to an output
block, failure promoted to an output block or a physical
contact. When Fault State condition is set, then output
function blocks will perform their FSAFE actions.
