Identifier Function Description
Joystick Velocity Select. Allows you to select the velocity for joystick motion. The JOYVH and
O
JOYVL commands establish two joystick velocities. Opening the Velocity Select input (input is
high) selects the JOYVH configuration. Closing the Velocity Select input (input is low) selects the
JOYVL configuration. The JOYVL velocity could be used to quickly move to a location, the JOYVH
velocity could be used for low-speed accurate positioning. NOTE: When this input is not
connected, joystick motion always uses the JOYVH velocity setting.
Program Select. One to one correspondence for input vs. program number. The program
aP
number comes from the TDIR command. The number specified before the program name is the
number to specify within this input definition. For example, in the 2INFNC1-3P command, 3 is the
program number. An input defined as a Program Select Input will not function until the INSELP
command has been enabled.
Program Security. Issuing the INFNCi-Q command enables the Program Security feature and
Q
assigns the Program Access function to the specified programmable input.
The program security feature denies you access to the DEF, DEL, ERASE, MEMORY,INFNC and
LIMFNC commands until you activate the program access input. Being denied access to these
commands effectively restricts altering the user memory allocation. If you try to use these
commands when program security is active (program access input is not activated), you will
receive the error message *ACCESS DENIED. The INFNCi-Q command is not saved in battery-
backed RAM, so you may want to put it in the start-up program (STARTP).
For example, once you issue the 3INFNC12-Q command, the input on the 4
point 12) of I/O brick 3 is assigned the program access function and access to the DEF, DEL,
ERASE, MEMORY, INFNC, and LIMFNC commands will be denied until you activate the input.
To regain access to these commands without the use of the program access input, you must
issue the INEN command to disable the program security input, make the required user memory
changes, and then issue the INEN command to re-enable the input. For example, if input 3 on
brick 2 is assigned as the Program Security input, use 2INEN.3=1 to disable the input and leave
it activated, make the necessary user memory changes, and then use 2INEN.3=E to re-enable
the input.
End-of-Travel Limit, Positive Direction. This assigns the positive direction end-of-travel limit
R
input function. For example, INFNC1-R assigns the "Positive EOT limit" function to general-
purpose input #1. "Positive direction" correlates to motion in the positive-counting direction as
reported with TPE and TPC. REMEMBER: Once an input is assigned a limit function, it is no
longer debounced (INDEB has no effect), and it must be enabled/disabled with the LH command
instead of the INEN command.
End-of-Travel Limit, Negative Direction. This assigns the negative direction end-of-travel limit
S
input function. For example, INFNC2-S assigns the "Negative EOT limit" function to general-
purpose input #2. "Negative direction" correlates to motion in the negative-counting direction as
reported with TPE and TPC. REMEMBER: Once an input is assigned a limit function, it is no
longer debounced (INDEB has no effect), and it must be enabled/disabled with the LH command
instead of the INEN command.
Home Limit. This assigns the home limit input function. For example, INFNC3-T assigns the
T
"Home limit" function to general-purpose input #3. REMEMBER: Once an input is assigned a limit
function, it is no longer debounced. For more information on homing, refer to the HOM command
and the Homing section in the Programmer's Guide.
Example:
3INFNC1-D
; Input at I/O point #1 on brick 3 is defined to be a stop input
