Momentary Pushbutton Module Datasheet

Overview

The Momentary Pushbutton Module, CE-MD-014-0001, extends MachineMotion 2’s functionality with two momentary pushbuttons. This plug-and-play module only requires a single connection to the MachineMotion 2 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 eight modules per MachineMotion 2 controller.

For details on Vention’s Latching Pushbutton Module, refer to the ‘Documentation for Previous Product Versions’ section at the bottom of this page.

Features

• Includes two momentary pushbuttons
• Connects (daisy chain) with compatible modules
• Configurable address

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)
