homebridge-plc

Homebridge plugin for Siemens Step7 and compatible PLCs

SIEMENS S7 PLC plugin for Homebridge

• Uses snap7 for communication therefore compatible with:
  • S7 300
  • S7 400
  • S7 1200 see Snap7 notes
  • S7 1500 see Snap7 notes
  • and compatible PLCs e.g. Yaskawa or VIPA
  • uses PG-Communication (programming device communication) to connect the PLC
  • optional also OP-Communication (HMI or panel communication) can be used for to connect the PLC
  • NOTE: You may need to increase the connection resources for PG-Communication or OP-Communication within Siemens Simatic Manager or Siemens TIA Portal. The default value is 1 and thus lead to connection problems using programming tool or panel and this plugin at the same time.
• Tested with S7-300, S7-1200 and S7-300 compatible PLCs from Yaskawa
• Implementation is based on documentation of the Homebridge API
• Supports polling of PLC from homebridge-plc plugin by per accessory defined interval

Homebridge configuration

Platform

The plugin is configured as single platform by defining a PLC platform. Parameters:

• ip: the IPv4 address of the PLC
• rack: the rack number of the PLC typically 0
• slot: the slot number of the PLC for S7 300/400 typically 2, for 1200/1500 typically 1.
• communicationOP: (optional) when set to true OP-Communication is used instead of PG-Communication
• enablePolling: (optional) when set to true a background task is executed every second enable polling for the accessories
• defaultPollInterval (optional) default polling interval for all accessories in seconds. Default value is 10 seconds
• distributePolling (optional) when set to true the polling of the accessories does not start at the same time. In order to distribute the PLC load for the queries
• enablePush: (optional) when set to true a the configured port is opened to push updates of values form plc to the plugin
• enableControl: (optional) when set to true a the configured port is opened to control accessories by http request
• port: (optional) port for http server to handle incoming http requests for push and control functionality. Default port is 8888
• forward: (optional) there is a limit of maximum 149 supported accessories by homebridge. To overcome this is limited you can create a second instance of homebridge running homebridge-plc and forward all push and control with no matching db to the other instance. Set the destination address of the second instance e.g. http:\\127.0.0.1:8889.
• mirror (optional) There are environments where it could make sense to share the same accessories on two homebridge instances. To allow pairing with another Home with Apple Home App or Home Assistant. This option mirrors all values read from PLC by this instance to a second instance. It also forwards all push requests to the second instance. The option enablePush has to be enabled on the second instance. on the destination instance. Set the destination address of the second instance e.g. http:\\192.168.1.11:8888. (expirimental feature)

Accessories

• In the platform, you can declare different types of accessories
• The notation (push support) identifies that parameter supports direct updates from the PLC
• The notation (control support) identifies parameters that can be controlled by http request
