CLICK PLC C2-NRED Aedes MQTT: Revolutionizing Automation Communication In the rapidly evolving world of industrial automation, efficient communication between devices is crucial for the success of any operation. Enter the CLICK PLC C2-NRED with its innovative Aedes MQTT Broker node. This Node-RED node revolutionizes how we perceive automation networking. You can now install an MQTT Broker in the industrial environment without using a server on your network. This will speed up your MQTT communication. We will install the Node-RED Aedes MQTT broker on our Click PLUS PLC C2-NRED module. The clients will subscribe and publish to this broker. Node-RED nodes, MQTT In and Out, will be used in the C2-NRED. We will also use the BRX Do-More PLC and the Click PLUS MQTT communications to create three connections. Let's get started. For more information, please visit our website. This includes all of the links mentioned in this video. https://accautomation.ca/click-plc-aedes-mqtt-what-is-the-big-deal/ 00:00 Click PLC & AEDES MQTT: What is the Big Deal? 01:18 What is MQTT? 02:01 Integration of Aedes with CLICK PLC C2-NRED 05:21 MQTT IN / OUT in Node-RED (Client) 09:44 BRX Do-More MQTT 13:19 Click PLUS PLC MQTT Previously, we looked at the following using C2-NRED Node-RED: CLICK PLUS C2-NRED: Easy Install for PLC Module! https://accautomation.ca/click-plus-c2-nred-easy-install-for-plc-module/ https://youtu.be/ZFgcVwCYCRk Unleash Innovation: Node-RED Flow in Click PLC https://accautomation.ca/unleash-innovation-node-red-flow-in-click-plc/

as
1:19
well what is MQTT
1:23
mqtt or message queuing telemetry
1:25
transport is a lightweight messaging
1:27
protocol for low bandwidth high legacy
1:30
networks mqtt is a widely used in IoT or
1:34
internet of things systems where it
1:36
facilitates communication between
1:38
different devices and applications
1:39
ensuring reliable data transfer and
1:42
real-time
1:43
monitoring the 80s MQTT broker can
1:46
handle a considerable number of clients
1:48
while specific numbers may vary based on
1:50
hardware and configuration AES has been
1:53
designed to be highly scalable and can
1:55
support tens of thousands even
1:57
potentially hundreds of thousands of
1:58
concurrent
2:01
connections integration of 80s with
2:03
Click Plus PLC C2N
2:07
red previously we installed the 80s node
2:10
on our C2N red module the C2N red mounts
2:14
in a PLC slot of the Click Plus click
2:18
MQTT can be implemented easily for
2:20
real-time data transfer between
2:22
different devices in our

4:46
Plus
4:47
PLC our 80s broker is now set up on our
4:50
C2 and Red module think of the broker as
4:53
a filing cabinet this is a storage
4:56
device for information
4:58
if information is placed in the cabin
5:00
the clients who want it will
5:01
automatically receive it when it changes
5:03
in MQTT this is referred to as
5:05
subscribing and
5:21
publishing MQTT in out in Node Red
5:26
client we will publish the eight point
5:29
outputs of address 101 of our Click Plus
5:32
PLC
5:38
click and drag an inject click read
5:40
function and MQTT output node onto our
5:45
workspace we'll also add debug nodes
5:48
between the click read and the function
5:51
and between the function and the MQTT
5:54
out
5:57
nodes double click on the click read
5:59
node select the memory type as output
6:02
point Y the address will be 101 and the
6:05

6:30
double click on the function node we
6:32
will change the onssage code to the
6:36
following message.payload equals
6:40
message.payload.data return
6:44
message this separates the status of the
6:47
read information in the click PLC to
6:49
just the data select done
6:54
double click on the MQTT out
7:12
node our server will be set up for the
7:14
AD server we just configured the topic
7:17
we choose is similar to our filing
7:19
cabinet example in our case we'll make
7:21
it click backslash
7:24
outputs when setting up your network
7:26
consider future expansion and how this
7:28
information will be utilized the unified
7:31
name space can be used for your
7:33
organization qos or quality of service
7:37
responds to increasing levels of
7:38
reliability for message delivery we will
7:41
set ours for two this ensures that the
7:43
messages are delivered exactly once
7:45
without duplication
7:47
we will also set the retain to true to
7:50
ensure that our values are remembered
7:52
select
7:57
[Music]

8:14
our server will be populated with our8s
8:17
broker address we will subscribe to the
8:19
single topic click backslash outputs
8:22
ensure the topic matches to one
8:25
specified in the MQTT output node we
8:28
will set our QoS to two and use the auto
8:32
detect for our output select
8:35
done select deploy to write our flow
8:38
program into the C2N module select the
8:41
inject mode to test our flow
8:44
you will see our output array from our
8:46
click read going to the MQTT out node
8:50
publish the MQTT broker will then send
8:53
the information out to our MQTT in node
8:55
that we are subscribing
9:12
you will also notice that the 80s MQTT
9:14
sends out a heartbeat allowing us to
9:16
know that it is still
9:19
active mqtt communication employs a
9:22
report by exception approach resulting
9:24
in a quick communication method due to
9:26
its low network
