Chapter 3 Embedded I/O

Local:4:O.OutputOnMask Setting a bit in this tag to 1 turns ON the corresponding HSC output, regardless of

the counter-controlled range results. Setting a bit to 1 in this tag turns ON the

corresponding HSC output, even if the HSC (that can control the outputs

independently) commands the opposite.

If a HSC output has both its OutputOnMask bit set to 1 and its OutputOffMask bit

set to 0, the OutputOffMask is precedent and the output is in the OFF state.

Use this tag in your program logic for direct control of the embedded HSC outputs.

Local:4:O.OutputOffMask Setting a bit in this tag to 0 turns OFF the corresponding HSC output regardless of

the counter-controlled range results or the value specified in the OutputOnMask bit.

Setting a bit to 0 in this tag turns OFF the corresponding HSC output, even if the

HSC (that can control the outputs independently) commands the opposite.

To allow an HSC output to be controlled (that is, to be turned ON), either by the

program logic or the HSC’s range results, set the corresponding output’s

OutputOffMask bit to 1.

Local:4:O.RangeEnX These tags provide control bits for enabling range results output control.

Local:4:O.ResetBlownFuse Use this tag to reset the outputs' overcurrent status bits (in the input array tag

StatusFlags) if the over current latch is on.

Local:4:O.CtrX The bits of this tag are used to control counter X operation settings.

Local:4:O.CtrXEn This tag value controls whether the HSC inputs can affect the counter’s current

count value. Setting the bit to 1 enables counting, setting the bit to 0 disables

counting.

Local:4:O.CtrXSoftPreset Use this tag to force a preset of counter X to the CtrPreset value. The transition of

the SoftPreset from 0 to 1 causes the counter to transition to the preset value.

Local:4:O.CtrXResetCountOverflow Use this tag to clear the counter overflow bit for counter X (the Overflow tag for the

counter is located in the array Local:4:I.CtrXStatus).

The transition of the ResetCountOverflow tag from 0 to 1 causes the CtrXOverflow

tag value to be cleared.

Local:4:O.CtrXResetCountUnderflow Use this tag to clear the counter underflow bit for counter X (the underflow tag for

the counter is located in the array Local:4:I.CtrXStatus).

The transition of the ResetCountUnderflow tag from 0 to 1 causes the

CtrXUnderflow tag value to be cleared.

Local:4:O.CtrXDirectionInvert Use this tag to control the count direction (higher or lower) of counter X if the

CtrDirectionInhibit tag for the counter is set.

A 0 value in this DirectionInvert tag causes the count to increase when the

counter's input signals dictate a change in count.

A 1 value in this DirectionInvert tag causes the count to decrease when the

counter's input signals dictate a change in count.

Local:4:O.CtrDirectionInhibit Use this tag to control the count direction source for counter X.

A 0 value in this DirectInhibit tag allows the HSC inputs to control the count

direction. A 1 value in this DirectionInhibit tag allows the controller (that is, the

value of the DirectionInvert tag) to control the count direction.
