I/O Embedded Function

Overview

The embedded I/O function allows configuring of the controller inputs.

The table describes the digital inputs of the controllers:

Reference	Digital Input	Digital Output
HMISCU6A5	14 regular inputs and 2 fast inputs (HSC)	8 regular outputs and 2 fast outputs (PTO)⁽¹⁾
HMISCU8A5
HMISAC
HMISCU6B5	6 regular inputs and 2 fast inputs (HSC)	6 regular outputs and 2 fast outputs (PTO)⁽¹⁾
HMISCU8B5
HMI SBC
1 The fast outputs can be used either as regular outputs or as fast outputs for Pulse Train Output (PTO), Pulse Width Modulation (PWM) functions, or reflex output for high speed counter (HSC).

Accessing the I/O Configuration Window

Step	Description
1	Click HMISCUxx5 > Embedded Functions > IO in the Devices tree.
2	Click the I/O Configuration tab.

I/O Configuration Window

The window allows you to configure the embedded digital inputs:

NOTE: If the selection is gray, the parameter is unavailable.

NOTE: For more information on the I/O Mapping tab, refer to the CoDeSys online help in SoMachine.

When you click the IO Summarize button, the IO Summary window appears. It allows you to check your configured I/O mapping:

Configuration Parameters

For each digital input, you can configure the parameters:

Parameter	Value	Description	Constraint
Filter	No* 3 ms 12 ms	Reduces the effect of noise on a controller input.	Available if Latch and Event are disabled. In the other cases, this parameter is disabled and its value is No.
Latch	No* Yes	Allows incoming pulses with amplitude widths shorter than the controller scan time to be captured and recorded.	This parameter is only available for fast inputs FI0 and FI1. Available if Run/Stop is disabled.
Event	No* Rising edge Falling edge Both edges	Event Detection for the purpose of triggering an External Task.	This parameter is only available for fast inputs FI0 and FI1. Available if both Latch and Run/Stop are disabled.
Bounce Filter	4 µs* 40 µs	Reduces the effect of bounce on a controller input.	Available if Latch is enabled or Event is enabled. In the other cases, this parameter is disabled and its value is 4 µs.
Run/Stop	No* Yes	The Run/Stop input can be used to run or stop a program in the controller.	Any input can be configured as Run/Stop, but only one input can be configured for this purpose.
* parameter default value

NOTE: The parameter is unavailable if the selection displays as gray in color.

Run/Stop Input

This table presents the different states:

Input states	Result
State 0	Stops the controller and ignores external Run commands.
A rising edge	From the STOPPED state, initiate a start-up of an application in RUNNING state.
State 1	The application can be controlled by: oSoMachine (Run/Stop) oapplication (Controller command) onetwork command (Run/Stop command)

Input states

Result

State 0

Stops the controller and ignores external Run commands.

A rising edge

From the STOPPED state, initiate a start-up of an application in RUNNING state.

State 1

The application can be controlled by:

oSoMachine (Run/Stop)

oapplication (Controller command)

onetwork command (Run/Stop command)

NOTE: Run/Stop input is managed even if the option Update I/O while in stop is not selected in Controller Device Editor (PLC settings tab).

Inputs assigned to configured expert functions cannot be configured as Run/Stop inputs.

For further details about controller states and states transitions, refer to Controller State Diagram.

WARNING

UNINTENDED MACHINE OR PROCESS START-UP

oVerify the state of security of your machine or process environment before applying power to the Run/Stop input.

oUse the Run/Stop input to help prevent the unintentional start-up from a remote location.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
