1 .7 .FEATURES ./ .FEATURE_SEL .parameters
The .bit .strings .FEATURES .and .FEATURE_SEL .determine .optional .behaviour .of .the .resource . .
The .first .defines .the .available .features, .and .is .read .only . .The .second .is .used .to .turn .on .an .
available .feature .by .configuration . .If .a .bit .is .set .in .FEATURE_SEL .that .is .not .set .in .FEA-
TURES, .the .result .will .be .a .block .alarm .for .a .configuration .error . .The .device .supports .the .
following .features: .Reports .supported, .Fault .State .supported, .Soft .Write .lock .supported .
1 .8 .Fault .state .for .the .whole .resource
If .the .user .sets .the .SET_FSTATE .parameter, .the .FAULT_STATE .parameter .will .indicate .active .
and .it .will .cause .all .output .function .blocks .in .the .resource .to .go .immediately .to .the .condition .
chosen .by .the .fault .state .Type .I/O .option . .It .may .be .cleared .by .setting .the .CLR_FSTATE .pa-
rameter . .The .set .and .clear .parameters .do .not .appear .in .a .view .because .they .are .momentary .
1 .9 .Write .lock .by .software
The .WRITE_LOCK .parameter, .if .set, .will .prevent .any .external .change .to .the .static .or .non .
volatile .data .base .in .the .Function .Block .Application .of .the .resource . .Block .connections .and .
calculation .results .will .proceed .normally, .but .the .configuration .will .be .locked . .It .is .set .and .
cleared .by .writing .to .the .WRITE_LOCK .parameter . .Clearing .WRITE_LOCK .will .generate .the .
discrete .alert .WRITE_ALM, .at .the .WRITE_PRI .priority . .Setting .WRITE_LOCK .will .clear .the .
alert, .if .it .exists . .Before .setting .WRITE_LOCK .parameter .to .Locked, .it .is .necessary .to .select .
the .“Soft .Write .lock .supported” .option .in .FEATURE_SEL .
1 .10 . .Features .being .implemented
The .parameter .CYCLE_TYPE .is .a .bit .string .that .defines .the .types .of .cycles .that .this .resource .
can .do . .CYCLE_SEL .allows .the .configurator .to .choose .one .of .them . .If .CYCLE_SEL .contains .
more .than .one .bit, .or .the .bit .set .is .not .set .in .CYCLE_TYPE, .the .result .will .be .a .block .alarm .
for .a .configuration .error . .MIN_CYCLE_T .is .the .manufacturer .specified .minimum .time .to .ex-
ecute .a .cycle . .It .puts .a .lower .limit .on .the .scheduling .of .the .resource .
MEMORY_SIZE .declares .the .size .of .the .resource .for .configuration .of .function .blocks, .in .kilo-
bytes . .The .parameter .FREE_SPACE .shows .the .percentage .of .configuration .memory .that .is .
still .available . .FREE_TIME .shows .the .approximate .percentage .of .time .that .the .resource .has .
left .for .processing .new .function .blocks, .should .they .be .configured .
1 .11 .BLOCK_ERR
The .BLOCK_ERR .of .the .resource .block .will .reflect .the .following .causes:
Device .Fault .State .Set .– .When .FAULT_STATE .is .active .
Simulate .Active .– .When .the .Simulate .jumper .is .ON .
Out .of .Service .– .When .the .block .is .in .O/S .mode .
1 .1 .Supported .Modes
O/S, .IMAN .and .AUTO
