Supported MicroLogix Connection Methods

  • MicroLogix 1100 and 1400 direct

  • MicroLogix 1100 and 1400 connected through 1761-NET-ENI

  • MicroLogix 1100/1400 connected through Spectrum Controls WebPort 500

Important

MicroLogix 1200 and 1500 are not fully supported. Browsing is not available on these devices, so the 'Disable Processor Browse' advanced property will need to be set to True on the device connection.

Some Micrologix devices may get stuck in a 'Browse Pending' status. In this case setting the connection path property to 1,0 should resolve the issue.
