4 Typically, module profiles are made up of ID, ID1, ID2, and IO. NOTE: Certain older modules ( AS-Interface specification ) may have reduced profiles with only ID and addressing cable can be used on most AS-Interface modules using the addressing jack. 6 AS-Interface Maintenance Troubleshooting Guide1.

10 40 Offline phase: Gateway displays OFF-LINE by host Check Points n No power to AS-Interface network, causing it to be offline n Network has been taken offline manually using gateway display or toggling F0 bit in the PLC output image. 41 Detection phase: Gateway remains in this state until at least one node is found. Check Pointsn Place nodes on network, making sure there are no duplicate addresses. n Check to ensure that exactly one power supply is used for each AS-Interface segment. HINT: This can be easily verified by powering down each of the AS-Interface power supplies, one at a time. The PWR LEDs on all of the nodes within each segment should turn off. The U-AS-i LED on the segment connected to the AS-Interface gateway/scanner should turn Make sure the AS-Interface power supply is not being used to power auxiliary devices.
