2.4 LED Indicator Specifications

2.4 LED Indicator Specifications

The LED indicator specifications for the 260IF Module are shown in the following table.

		Table 2.3	LED Indicator Specifications
Indicator	Color	Status		Meaning
MS	Red/Green	Not lit		No power to the 260IF Module.
		Lit green		Operating normally.
		Lit red		Self-diagnostic error or WDT error.
NS	Red/green	Not lit		No power to the 260IF Module/offline.*1
		Flashing green		Online but not connected.
		Lit green		Online and connected.
		Flashing red		No-DeviceNet communications error.
		Lit red		Communications not possible (duplicate MAC ID),
				bus-off error, or WDT error.*2

1. The 260IF Module is offline for the two seconds from the completion of the indicator test after startup through the completion of the MAC ID duplication check. The 260IF Module is online after the MAC ID duplication check at startup has been completed.

2. When the network power supply is OFF, the 260IF Module automatically resets as specified in the DeviceNet specifications even if a busoff error occurs. At the same time, the NS indicator will light red for a moment and then go OFF again immediately. After power has been restored to the network, the green NS indicator will start flashing (online but not connected).

The following diagram shows the indicator test sequence that is performed immediately after the power is turned ON. Check the ON and OFF status of these indicators for any malfunctions. About 1 second is required for this test.

Configuration Elements

The network is configured from the following elements.

Nodes

A node is either a slave that connects to external I/O, or the Master, which manages the I/O of the slaves. There are no restrictions on the locations of the Master or Slaves. Any node in the figure above can be the Master or a Slave.

Trunk Line and Drop Lines

A cable with a terminator on each end is the trunk line. Any cable branching from the trunk line is a drop line.

Connection Methods

A node is connected using the T-branch method or multi-drop method. A T-Branch Adapter is used to connect a node with the T-branch method. A node is directly connected to the trunk line or a drop line with the multi-drop method. Both T-branch and multi-drop methods

3-2

3.1 Network Configuration

can be used together in the same network, as shown in the figure above.

Terminators

Both ends of the trunk line must connect to terminating resistance to decrease signal reflection and ensure stable network communications.

Communications Power Supply

The communications connectors of each node must be provided with communications power supply through the communications cable for DeviceNet communications. Communications power supply, internal circuit power supply, and I/O power supply must all be provided separately.

INFO

1 Use only DeviceNet cables as communications cables.

2 Always connect terminators to both ends of the trunk line.

3 Do not connect lightning arresters or any devices to the network other than the 260IF Module and DeviceNet-conforming products.
