1.0 The Resource Block, Fieldbus Foundation
1 .1 .Introduction
The .resource .block .is .used .to .define .a .hardware .specific .characteristics .of .the .function .block .
applications . .It .provides .WIKA .manufacturer’s .name, .device .name, .DD .and .block .status .and .
hardware .details . .It .also .indicates .how .much .resource .(memory .and .CPU) .is .available .and .
controls .the .overall .device . . .
1 . .Description
This .block .contains .data .that .is .specific .to .the .hardware .that .is .associated .with .the .resource . .
All .data .is .modelled .within .a .controlled .space, .so .there .are .no .outside .inputs .into .this .block .
required . . .
.
This .parameter .“set” .is .intended .to .be .the .minimum .required .for .the .Function .Block .Applica-
tion .associated .with .the .resource .in .which .it .resides . .Some .parameters .that .could .be .in .the .
set, .like .calibration .data .and .ambient .temperature, .are .more .part .of .their .respective .trans-
ducer .blocks . .The .“mode” .is .used .to .control .major .states .of .the .resource . .O/S .mode .stops .
all .function .block .execution . .The .actual .mode .of .the .function .blocks .will .be .changed .to .O/S .
(out .of .service), .but .the .target .mode .will .not .be .changed . .Auto .mode .allows .normal .operation .
of .the .resource . .IMan .shows .that .the .resource .is .initializing .or .receiving .a .software .down-
load . .Parameters .MANUFAC_ID, .DEV_TYPE, .DEV_REV, .DD_REV, .and .DD_RESOURCE .are .
required .to .identify .and .locate .the .DD .so .that .Device .Description .Hosting .Services .can .se-
lect .the .correct .DD .for .use .with .the .resource . .The .parameter .HARD_TYPES .is .a .read .only .bit .
string .that .indicates .the .types .of .hardware .that .are .available .to .this .resource . .If .an .I/O .block .
is .configured .that .requires .a .type .of .hardware .that .is .not .available, .the .result .will .be .a .block .
alarm .for .a .configuration .error . .The .RS_STATE .parameter .contains .the .operational .state .of .
the .Function .Block .Application .for .the .resource .containing .this .resource .block .
1 .3 .RESTART .parameter
The .RESTART .parameter .allows .degrees .of .initialization .of .the .resource . .They .are: . .
1 .- .Run: .it .is .the .passive .state .of .the .parameter .
 .- .Restart .resource: .it .is .intended .to .clear .up .problems .for .example .the .memory .manage-
ment .resource . .
3 .- .Restart .with .defaults: .it .is .intended .to .wipe .configuration .memory, .it .works .like .a .factory .
initialization . .
4 .- .Restart .processor: .it .provides .a .way .to .hit .the .reset .button .on .the .processor .associated .
with .the .resource .This .parameter .does .not .appear .in .a .view .because .it .returns .to .1 .shortly .
after .being .written .
1 .4 .Non-volatile .parameters
All .non-volatile .parameters .are .saved .in .EEPROM .and .therefore .used .if .the .device .is .restart-
ed .
1 .5 .Timeout .for .remote .cascade .modes
SHED_RCAS .and .SHED_ROUT .set .the .time .limit .for .loss .of .communication .from .a .remote .
device . .These .constants .are .used .by .all .function .blocks .that .support .a .remote .cascade .
mode . .The .effect .of .a .timeout .is .described .in .Mode .Calculation . .Shedding .from .RCAS/ROUT .
shall .not .happen .when .SHED_RCAS .or .SHED_ROUT .is .set .to .zero .
1 .6 .Alert .Notification
The .MAX_NOTIFY .parameter .value .is .the .maximum .number .of .alert .reports .that .this .resource .
can .have .sent .without .getting .a .confirmation, .corresponding .to .the .amount .of .buffer .space .
available .for .alert .messages . .A .user .can .set .the .number .lower .than .that, .to .control .alert .
flooding, .by .adjusting .the .LIM_NOTIFY .parameter .value . .If .LIM_NOTIFY .is .set .to .zero, .then .
no .alerts .are .reported . .The .CONFIRM_TIME .parameter .is .the .time .for .the .resource .to .wait .for .
confirmation .of .receipt .of .a .report .before .trying .again . .If .the .CONFIRM_TIME .= .0 .the .device .
shall .not .retry .
