4.      Input Definitions

Fill in the blanks style table(s) used to help you define and assign the Inputs required for your machine.  Please note that there is a different Input Definition table for each type of PLC.  Please be sure that the Input Definition table that you fill out corresponds to the hardware you have ordered.       

5.      Output Definitions

Fill in the blanks style table(s) used to help you define and assign the Outputs required for your machine.  Please note that there is a different Output Definition table for each type of PLC.  Please be sure that the Output Definition table that you fill out corresponds to the hardware you have ordered.      

6.      Definitions of Functions and Macros

This section is used to help define the functions, sequences and macros required for your machine.

PLC Build Sheet

Definition of Terms

D                     Dedicated  Indicates that this type can not be changed.

INT                 Internal types are reserved for internal operations.

Function         This should be an exhaustive definition of a required control and or PLC response to a specified event.  The trigger event may be the transition of an input, the expiration of a timer, an output being set or any other event visible to the PLC  Also, when labeling the “Function” sections in the input or output tables, make sure the label you use matches the title of a Function in the “Definitions of Functions, Sequences and Macros” section. 

  

Input State     N/C - Normally Closed or N/O – Normally Open.  This is typically the state that the device will transition from to indicate an event has occurred and a PLC action is to take place.  For example:  For fail safe reasons, limit switches are wired in a “Normally Closed” (N/C) configuration.  The transition of a limit switch input from its “closed” state to an “open” state signals that a fault has occurred and the defined action or function(s) should be executed.

Input Type    SI - Sinking inputs are considered “closed” when a specified voltage is detected on the input.  That voltage is typically provided through a switch but PNP or NPN devices may also be used. 

SR - Sourcing inputs provide an internally supplied voltage and are considered “closed” when an external device pulls that voltage level to ground.  The device used is typically a switch but PNP or NPN devices may also be used.

INT – Internal input are dedicated inputs which can not be re-assigned.

CFG – Configurable inputs may be designated either SI or SR and configured for 5,12 or 24VDC

VDC               5, 12 or 24VDC

                       

Out. Type       OC Open Collector outputs are low power outputs.  OC type outputs should only be used to drive digital devices or small “ice cube” style relays, they should NOT be used to drive contactors or solenoids.  OC type outputs are rated for 5VDC @90ma.  If your device has higher power requirements, an intermediate relay must be used.

SPST An output defined as SPST will be wired to supply the specified voltage for that output when it is turned on. 

SPDT Only available on designated outputs, an SPDT output is wired to supply the specified voltage for that output to the N/C terminal when off and to the N/O terminal when the output is on.  The SPDT output type is especially useful for forward/reverse motor control (such as a spindle or carousel motor) because the design of the relay prevents both output terminals from being powered simultaneously.  The SPDT output type can also be used as an SPST type output if needed. 

Analog outputs typically supply 0 to +10 VDC and are used almost exclusively to supply a reference voltage to a frequency inverter.

Jog Panel Definitions

The Jog Panel offers 9 definable keys for custom auxiliary functions and includes keys for handling pre-defined functions used for cycle start and cycle cancel, axis jogging (incremental and continuous), spindle and coolant operation, tool check, single block mode and feed hold.

In the example above, auxiliary key #1 is assigned to toggle   the spindle brake mode between auto and off.  If auto brake mode is active the spindle brake is typically programmed to automatically turn on if the spindle is commanded to stop and to turn off when the spindle is commanded to start.  This is a loose definition and is intended as an example only as several variations of “auto brake mode” may exist.   

Some functions you may want to consider assigning an aux key to include:

                                                                                                               

Turning on a Work light, Indexing a tool carousel, Set part zero, Clamp on/off etc, Auger on/off etc. . . .

Definitions of Functions and Macros

Centroid wants to supply exactly what you ordered.  To do so, it is very important that you provide accurate and complete definitions for all your requested functions and macros.  If you have any questions, please call and we will help you complete this form.  It is your responsibility to insure that the Function and Macro definitions you provide are exactly as you require them.  If you discover changes are necessary after your PLC build sheet has been submitted, contact us immediately. Changes after programming has begun are $75/hr, $250 minimum.  

Function and Macro definitions must include the following:

1. Title
2. The trigger event.
3. A list of Inputs and Outputs traversed in the function.
4. A list of all requested fault conditions associated with this function and their respective triggers. 
5. A timeout specification (if applicable).  This timeout should be the amount of time in which the function can reasonably be expected to successfully complete.  If the timeout period is exceeded, the appropriate fault condition should be declared and the function terminated.
6. The sequence of events.  The sequence of events must include:

a)      The order of events, beginning with the trigger.

b)      Initial states for all I/O.

c)      All state changes, in the order that they should occur.

d)     Required dwell times (if any) such as a dwell needed to wait for the spindle to stop

Function and Macro definitions must use the following format:

Function or Macro Title:

Physical I/O traversed in this function:

Inputs:

 

Outputs: 

Fault Conditions:

Function or Macro timeout:

Trigger:

Initial I/O states :                               Outputs- On = X.           Inputs- Closed = X

Additional considerations and fault conditions/timeouts you may want to add to the above function:

1. Turn all or some of the outputs on only momentarily.  Either until specified event occurs, for a specific period of time or a combination of both.  This can help to prevent motors and solenoids from burning up.
2. Add fault conditions/timeouts between some or all the events in the sequence to insure that if an operation fails to complete in a reasonable period of time, a fault condition can be declared and appropriate error message displayed.  Ex.   For Events 7-9, a timer could be so that if the Carousel IN input does not close within .5 seconds of the Carousel In Output being turned on, a fault is declared and the message  “Error: Carousel In Input sensor did not close after Carousel In Ouput was turned on”
