Loggers - Device Connections: Siemens – Inductive Automation Australia

This article covers loggers related to Siemens device connections that were introduced in Ignition version 7.8.X.

Loggers in this article:

drivers.S7{Generation}Driver[{DeviceConnectionName}]

drivers.S7{Generation}Driver[{DeviceConnectionName}]

A series of loggers monitoring connection status and tag subscriptions using one of the Siemens drivers. {Generation} is denoted as Siemen’s Step 7 line driver options (300,400,1200,1500). {DeviceConnectionName} is denoted as the name of the specific Siemens device connection in the Ignition config.

drivers.S7{Generation}Driver[{DeviceConnectionName}]

Will show the output of the connection when it is first established.

DEBUG log showing a successful device connection when it is first created, then disabled in the Ignition config:

Acquired connect permit, calling connect().
