5 Modules
5.6.4 DeviceNet Interface Module (260IF)
5-130
„ Rotary Switches SW2 and SW3
The SW2 and SW3 are used to set the MAC ID of the DeviceNet.
„ LED Indicators
The following table shows the LED indicator display patterns.
* 1. Offline status: Status from the time the LED test after startup com-
pletes to the time the MAC ID duplication check completes (2 sec-
onds)
Online status: Status after the MAC ID duplication check completes at
startup
* 2. If a DeviceNet bus OFF error occurs due to disconnection from the
power supply, the 260IF Module executes the Automatic Reset opera-
tion according to the DeviceNet specifications. In this case, the NS
lights up in red in a instant, then lights out. When the network power
supply is restored, the NS will start blinking in green (no connection
being established in online).
The 260IF executes the MS and NS LED check for one second when the power is turned ON
according to the DeviceNet Specifications. The following figure shows the LED display
during the LED test.
