Pattoo BACnet/IP Agents¶
pattoo_agent_bacnetipd
polls BACnet Analog Value
data from BACnetIP enabled systems and reports it to the pattoo
server.
Installation¶
These steps outline what needs to be done to get pattoo_agent_bacnetipd
working.
- Follow the installation steps in the Basic Installation file.
- Configure the
pattoo.yaml
configuration file following the steps in Configuration Guide. This file tellspattoo_agent_bacnetipd
, and all other agents, how to communicate with thepattoo
server. - Create a
pattoo_agent_bacnetipd.yaml
configuration file. Details on how to do this follow. - Start the desired daemons as explained in sections to follow. You may want to make these
systemd
daemons, if so follow the steps in the Basic Installation file.
Setting the Configuration Directory Location¶
pattoo_agent_bacnetipd
is a standard pattoo
agent and needs its configuration directory defined by using the PATTOO_CONFIGDIR
environmental variable. Here is how to do this from the Linux command line:
$ export PATTOO_CONFIGDIR=/path/to/configuration/directory
pattoo_agent_bacnetipd
client will read its own pattoo_agent_bacnetipd.yaml
configuration file located this directory when PATTOO_CONFIGDIR
is set.
You can automatically set this variable each time you log in by adding these lines to your ~/.bash_profile
file.
export PATTOO_CONFIGDIR=/path/to/configuration/directory
Make sure that files in this directory are readable by the user that will be running standard pattoo
agent daemons or scripts.
Configuring pattoo_agent_bacnetipd.yaml
¶
Let’s get started on configuring pattoo_agent_bacnetipd.yaml
.
pattoo_agent_bacnetipd
Section¶
Here is a sample of what should be added. An explanation follows.
NOTE: The indentations in the YAML configuration are important. Make sure indentations line up. Dashes ‘-‘ indicate one item in a list of items.
pattoo_agent_bacnetipd:
polling_interval: 300
polling_groups:
- group_name: GROUP 1
ip_devices:
- ip.address.of.device1
- ip.address.of.device2
points:
- address: 162
- address: 181
- address: 1
- address: 2
- address: 3
- group_name: GROUP 2
ip_devices:
- ip.address.of.device3
- ip.address.of.device4
points:
- address: 134
multiplier: 8
- address: 136
multiplier: 10
- address: 144
- address: 158
Configuration Explanation¶
This table outlines the purpose of each configuration parameter
Section | Sub-Section | Config Options | Description |
---|---|---|---|
pattoo_agent_bacnetipd: |
|||
polling_interval |
The pattoo_agent_bacnetipd will report to the pattoo server every polling_interval seconds |
||
polling_groups: |
List of groupings of ip_devices that need data from a shared set of BACnet points (For example the same manufacturer’s make and model). Make this the first entry in the configuration sub-section. Make sure it starts with a dash ‘-‘ which indicates the beginning of a new grouping. |
||
group_name: |
Unique name for a group of ip_devices that share the same BACnet parameters |
||
ip_devices: |
List of ip_devices to poll for data |
||
points: |
BACnet Analog Value point to poll for data from for the ip_devices . Each address must be a BACnet point. The multiplier is the value by which the polled data result must be multiplied. This is useful in converting byte values to bits. The default multiplier is 1. |
Polling¶
Use pattoo_agent_bacnetipd
to poll your devices. The daemon has a simple command structure below.
You will need a pattoo_agent_bacnetipd.yaml
configuration file in the PATTOO_CONFIGDIR
directory before you start.
$ bin/pattoo_agent_bacnetipd.py --help
usage: pattoo_agent_bacnetipd.py [-h] [--start] [--stop] [--status] [--restart]
[--force]
optional arguments:
-h, --help show this help message and exit
--start Start the agent daemon.
--stop Stop the agent daemon.
--status Get daemon daemon status.
--restart Restart the agent daemon.
--force Stops or restarts the agent daemon ungracefully when used with --stop or
--restart.
$
General Operation¶
Use these commands for general operation of the daemon.
Start Polling at Boot¶
Configuration Guide provides information on how to get the pattoo_agent_bacnetipd
daemon to start at boot.
Troubleshooting¶
Troubleshooting steps can be found in the PattooShared troubleshooting documentation
