Momentary Pushbutton Module Datasheet

Overview

The Momentary Pushbutton Module, CE-MD-014-0001, extends MachineMotion functionality with two momentary pushbuttons. This plug-and-play module only requires a single connection to the MachineMotion controller. Compatible modules, such as the Power Switch (CE-MD-005-0000) & additional pushbutton modules can also be daisy chained to each other, making it possible to connect up to sixteen modules per MachineMotion controller.

This document covers requirements for current version of MachineMotion controller. For previous version, refer to link below:

MachineLogic Sequence Example

Sequence example to handle a button being pushed and to change the LED color of the device to Green:

Topic for Wait For Event:

• If Black Button: devices/push-button-v2/+/digital-input/0

• If White Button: devices/push-button-v2/+/digital-input/1

Message: 1

Topic for Output Generate Event:

• devices/push-button-v2/+/set-led

Message: {“red”:0,”green”:1,”blue”:0}

How to replicate the LED color of the Access Request Module on the Momentary Pushbutton

If you are using the Momentary Pushbutton in conjunction with an Access Request Module (CE-SA-017-0001) you can use the example below to ensure that the LEDs have the same behavior. Follow these steps below:

1. Find your **Device ID ** as defined in Table 1 below

2. Find your Serial Number on the back of the Access Request Module

3. Add your Device ID & Serial Number in the example below

from machinelogic import Machine
import json
from time import sleep

access_request_serial_number = 1110003 # serial number can be found on device label
pushbutton_device_id = 1

m = Machine()
payload = "{}"
old_payload = None

def mirror_access_request_led(topic, message):
    global payload
    print("Access Request LED Change: ", message)
    message = json.loads(message.replace("'","\""))
    # incoming status will be: {"red": INT,"green":INT,"blue":INT,"blink": INT}
    red = message['red'] % 254
    green = message['green'] % 254
    blue = message['blue'] % 254
    payload = json.dumps({"red": red,"green":green,"blue": blue})

m.on_mqtt_event(
f'safety-module-hub/access-request/{access_request_serial_number}/led',
mirror_access_request_led
)

while True:
    if payload != old_payload:
        m.publish_mqtt_event(f'devices/push-button-v2/{pushbutton_device_id}/set-led', payload)
        old_payload = payload
    sleep(0.1)
