Stop
Supported Feature
Bus Element Bit 0-31 Polarity N.O./N.C. Width Offset
√
√
√
√
The “Stop” assignment will stop the tool if it is running
and prevent it from being started.
Reverse
Supported Feature
Bus Element Bit 0-31 Polarity N.O./N.C. Width Offset
√
√
√
√
The “Reverse” will put the controller in disassembly
mode while the input is active.
Disable
Supported Feature
Bus Element Bit 0-31 Polarity N.O./N.C. Width Offset
√
√
√
√
The “Disable” will disable the tool while the input is
active. It will not stop a fastening cycle that is progress.
Reset Job
Supported Feature
Bus Element Bit 0-31 Polarity N.O./N.C. Width Offset
√
√
√
√
On the transition of inactive to active the “Reset
Job” assignment will reset the active job.
Select PSet
Supported Feature

√
√
The “Select PSET” input will select the parameter
set according to the input value. Uses the width
parameter limit the width of the input bits read. The
minimum width is 1 and the maximum is 8. After the
input is read the offset parameter will be added to
the value do get the actual parameter set number.
Selecting an invalid parameter set number will
disable the tool.
Select Job

√
The “Select Job” input will select the job number
according to the input value. Uses the width
parameter limit the width of the input bits read. The
minimum width is 1 and the maximum is 8. After the
input is read the offset parameter will be added to
the value do get the actual job number. Selecting
an invalid job number will disable the tool.
Polarity
When the polarity is set to N.O. the input is
considered active high (24vdc for physical inputs
and logic 1 for all network type buses). When the
polarity is set to N.C. the input is considered active
low (0vdc for physical inputs and logic 0 for all
network type buses).
Width and Offset
For multiple bit inputs (for example “Select PSet”)
the width variable defines the number of bits the
assignment will read for its input. This allows the input
size to be restricted to a few bits saving space for
other assignments.
The offset variable allows a fixed value to be added
to the read value.
For example to use bits 4 & 5 of the physical inputs to
select parameter sets 1-4 the assignment would look
like…
Select PSet
Bus
1 For the physical bus
Element 0
For the first element on the bus
Bit
4 For the starting bit location
Width
2 To span the two bits 4 & 5
Offset
1 Adding 1 to the read input value so
we get…
Binary 00 = 1
Binary 01 = 2
Binary 10 = 3
Binary 11 = 4
