# Manufacturing Line PackML MQTT Simulator
> Manufacturing line simulator interfaced using PackML over MQTT.
PackML MQTT Simulator is a virtual line that interfaces using PackML implemented over MQTT. For use with the development of Industry 4.0 software solutions. The simulator implements the following PackML State model below and communicates over MQTT topics as defined by environmental variables. The simulator can run with either a basic MQTT topic structure or SparkPlugB.
The simulator supports the following topic and payload defintions:
- [Basic MQTT Topic Structure](#interfacing-via-basic-mqtt-topic-structure)
- [SparkplugB v1.0](#interfacing-via-sparkplugb-v10)
## Getting Started
To start and run the PackML simulation, you'll need an MQTT server running and accessible. Once available, the easiest approach is using docker to run the simulation using environmental variables to control the MQTT connection, Site, Area, and line.
### Docker
Start your container with environmental variables.
#### Basic MQTT Structure
```shell
$ docker run -it -e SITE=Site -e AREA=Area -e LINE=Line -e MQTT_URL=mqtt://broker.hivemq.com -m 30m spruiktec/packml-simulator
2020-06-22T03:13:49.301Z | info: Initializing
2020-06-22T03:13:49.817Z | info: Connected to mqtt://broker.hivemq.com:1883
2020-06-22T03:13:49.819Z | info: Site/Area/Line/Status/UnitModeCurrent : Production
```
Once up and running, use an MQTT client to publish to .../Command/Reset and .../Command/Start to get the simulated machine into the execute state. The default topic and payload is Custom as defined below.
#### SparkPlugB
```shell
$ docker run -it -e CLIENT_TYPE=sparkplugb -e SITE=Site -e AREA=Area -e LINE=Line -e MQTT_URL=mqtt://broker.hivemq.com -m 30m spruiktec/packml-simulator
2020-06-22T03:13:49.301Z | info: Initializing
2020-06-22T03:13:49.817Z | info: Connected to mqtt://broker.hivemq.com:1883
2020-06-22T03:13:49.819Z | info: Site/Area/Line/Status/UnitModeCurrent : Production
```
Once up and running, use an Sparkplug B device commands to publish to `Command/Reset` and `Command/Start` metrics to get the simulated machine into the execute state. The topic in the above example is: `spBv1.0/Site/DCMD/Area/Line`.
### Node

```
### Publish Commands for Basic MQTT Structure
Please allow some time in between commands to enable the machine to get to the Idle state before issuing the Start command.
```shell
$ docker run --init -it --rm efrecon/mqtt-client pub -h broker.hivemq.com -u USERNAME -P PASSWORD -t "Site/Area/Line/Command/Reset" -m 1
$ docker run --init -it --rm efrecon/mqtt-client pub -h broker.hivemq.com -u USERNAME -P PASSWORD -t "Site/Area/Line/Command/Start" -m 1
```
## Simulation
The simulation consists of
- On Startup, the machine will automatically enter the *Clearing* and then *Stopped* state
- PackML UnitMode command and status
- PackML State Model with commands and status
- Machine Speed (ramping up/down and flicker)
- Setpoint Observed
- Status of current speed
- Machine Design Speed Respected
- Counters
- 1x Consumed
- 1x Produced
- 1x Defective
- Automatic machine suspension/unsuspension from Execute state
- Echo's command of Parameters, RemoteInterface, and Products back onto the status tags
The simulation uses probability dice rolls to determine actions.
## interfacing via Basic MQTT Topic Structure
Interface with the virtual line via the basic MQTT structure. The virtual line subscribes to `///Command/*` (see below) and publishes information to `///Status` and `///Admin`. ``, `` and `` are set using environmental variables.

## Interfacing via SparkplugB v1.0
Refer to the [Sparkplug B Payload and Topic Payload Definition Specification](https://www.eclipse.org/tahu/spec/Sparkplug%20Topic%20Namespace%20and%20State%20ManagementV2.2-with%20appendix%20B%20format%20-%20Eclipse.pdf).
The simulator creates a device and listens to the device commands message (DCMD) topic with metrics representing the available commands without the `///` prefix. Consider the command topic `///Command/Reset`, when writing as a SparkplugB device command message use the metric name `Command/Reset`. Publishing device command messages are published against `spBv1.0//DCMD//` based on site environmental variables.
The simulator will also rebirth when requested at the node level by publishing to `spBv1.0//NCMD/` with a metric `Node Control/Rebirth` and a true value.
Below is an example of publishing to Igniition v8.1.5 SCADA with Cirrus Link Modules. The MQTT Engine was configured with the corresponding namespace filter for the simulation environmental variables.
## Environmental Variables
The application is configured using the following environmental variables:
### SITE
The ISA-95 Model site name of this line. SITE used as the parent topic in the MQTT structure. If this is unset, _Site_ will be used.
### AREA
The ISA-95 Model area name of this line. AREA used as the second topic in the MQTT structure. If this is unset, _Area_ will be used.
### LINE
The ISA-95 model line name of this line. LINE used as the third topic in the MQTT structure. If this is unset, hostname will be used.
### MQTT_URL
The address of the MQTT server. If this is unset, _mqtt://broker.hivemq.com_ will be used.
### MQTT_PORT
The port of the MQTT server. If left blank, the MQTT library will try and determine port based on protocol.
### MQTT_USERNAME
The name of the MQTT user with subscribe and publish permissions.
### MQTT_PASSWORD
The password for the MQTT user with subscribe and publish permissions.
### MQTT_CLIENT_ID
The client id to use when connecting to the broker. Defaults to hostname striped of special characters.
### CLIENT_TYPE
The topic and payload specification to use. Valid values are _mqtt_ and _sparkplugb_. Default to _mqtt_.
### SPARKPLUG_GROUP_ID
For use with Sparkplug B specifcation. Defines the group_id. Default value is the `SITE` environmental value or _PackML Simluator_ if `SITE` is not defined.
### SPARKPLUG_EDGE_NODE
For use with Sparkplug B specifcation. Defines the edge_node_id. Default value is the `AREA` environmental value or _site_area_line_ if `AREA` is not defined.
### TICK
The tick speed of the simulation in milliseconds. This is optional. Default is 1000.
## Enterprise Simulation
Use docker-compose to simulate multiple independent lines at once. E.g.
```yml
version: "2.4"

greenville-packaging-line1:
image: spruiktec/packml-simulator
environment:
SITE: Greenville
AREA: Packaging
LINE: 'Line 1'

mem_limit: 30MB
greenville-cnc-line1:

CLIENT_TYPE: sparkplugb
mem_limit: 30MB
```
## Contributing
For any issue, there are fundamentally three ways an individual can contribute:
- By opening the issue for discussion: For instance, if you believe that you have uncovered a bug in, creating a new issue in the [GitHub issue tracker](https://github.com/Spruik/PackML-MQTT-Simulator/issues) is the way to report it.
- By helping to triage the issue: This can be done either by providing supporting details (a test case that demonstrates a bug), or providing suggestions on how to address the issue.
- By helping to resolve the issue: Typically, this is done either in the form of demonstrating that the issue reported is not a problem after all, or more often, by opening a Pull Request that changes some bit of something in the simulator in a concrete and reviewable manner.
