SC Series Controllers
Configuration
Inputs
Description
Job: Type the job number to select when this input is asserted.
Disable when open:
Yes – Disables the tool when this input is removed.
No – Does not disable the tool upon input removal.
Spindle: Spindle: Type the spindle number in which the job is to be selected.
SELECT JOB
When asserted or removed on any input type, the controller selects a job. This is one bit, in a
(BIT)
series of bits, to create a binary number.
See SELECT TASK (BIT) function description for explanation of this bit (note that this
references Jobs not Tasks).
Size: 1 bit, except on fieldbus where it can be any size to fit the need.
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Bit: Type the number of this bit, in the binary number scheme, to select jobs.
Mode: All JOB SELECT BITs must be the same mode, modes cannot be mixed.
Binary – Creates a decimal number equivalent to the weighted value of this binary bit(s).
Binary + 1 – Creates a number equivalent to the weighted value of this binary bit(s) and adds
the value of one (1) to that number.
Spindle: Spindle: Type the spindle number in which the job is to be selected.
SELECT TASK When asserted, on any input type, the controller makes this input's Task the active Task.
When removed either nothing happens or if "Disable when open" is selected as yes, then the
tool becomes disabled.
Size: 1 bit
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
Task: Type the Task number to select when this input is asserted.
Disable when open:
Yes – Disables the tool when this input is removed.
No – Does not disable the tool upon input removal.
Spindle: Spindle: Type the spindle number in which the task is to be selected.
SELECT TASK
When asserted or removed, on any input bus, the controller selects a Task. This is one bit, in
(BIT)
a series of bits, to create a binary number.
The number created by this and other SELECT TASK BITs determines the active task for the
tool. More than one input assigned as a TASK SELECT BIT creates a number greater than
one. The maximum number of tasks required determines the maximum number of these
inputs.
In binary numbers, the digit furthest to the right is the ones digit. The next digit to the left is the
twos digit, next is the fours digit, then the eights digit, and so on. The integer equivalent to a
binary number can be found by summing all the weighted values of the selected digits. For
example, the binary number 10101 is equivalent to the integer 21. The math is 1 + 4 + 16 =
21: the high digits (one) are added together and the low digits (zero) are ignored.
Bit Number 4 3 2 1 0
Weighted Value 16 8 4 2 1
Binary Number 1 0 1 0 1
24V DC Pins (example) R P N M L
To select task #21 on the controller at least five inputs are assigned as TASK SELECT (BIT).
Each would then be given a bit number to have a series of bits with different weighted values.
For example, on the 24 VDC input pin L is bit 0, pin M is bit 1, pin N is bit 2, pin P is bit 3, and
pin R is bit 4. Therefore, to select task #21, assert pins L, N and R.
Size: 1 bit, except on fieldbus where it can be any size to fit the need.
Contact Type: Normally Open (N.O.), Normally Closed (N.C.)
