Warning

Please read this instruction carefully before use and follow this instruction to operate the device in order to prevent

damages on the device or injuries to staff.

Switch off the power before wiring.

RTU-DNET is an OPEN TYPE device and therefore should be installed in an enclosure free of airborne dust,

humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required for operating the enclosure) in case danger and damage on the device may occur.

RTU-DNET is to be used for controlling the operating machine and equipment. In order not to damage it, only

qualified professional staff familiar with the structure and operation of RTU-DNET can install, operate, wire and maintain it.

DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check

all the wirings again before switching on the power and DO NOT touch any terminal when the power is switched on. Make sure the ground terminal

2.5 Address Switch

The switch is used on setting up the node address of RTU-DNET on DeviceNet. Range: 00 ~ 63 (64 ~ 99 are

forbidden).

Switch setting Content

0 ~ 63 Valid DeviceNet node address

64 ~ 99 Invalid DeviceNet node address

Example: If you need to set the node address of RTU-DNET to 26, simply switch the corresponding swit ch of x101 to 2 and the corresponding switch of x10

to 6.

Note:

z Please set up the node address when the power is switched off. After the setup is completed, re-power

RTU-DNET.

z When RTU-DNET is operating, changing the setting of node address will be invalid. z Use slotted screwdriver to rotate the switch carefully in case you scratch the switch.

When DeviceNet is off, the I/O data in the buffer area will be cleared.

IN0

When DeviceNet is off, the I/O data in the buffer area will be held.

IN1 Reserved

Note:

z Please set up the function switch when the power is switched off. After the setup is completed, re-power

RTU-DNET.

z When RTU-DNET is operating, changing the setting of the function switch will be invalid. z Use slotted screwdriver to adjust the DIP switch carefully in case you scratch the switch.

2.7 Extension Port

The extension port is used on connecting RTU-DNET to DVP Slim DI/DO extension units and special modules.

3 Basic Operation

3.1 Connecting RTU-DNET to DVP Slim DI/DO Extension Unit

z Open the fixing clips on top and bottom of RTU-DNET. Meet the extension port of Slim DI/DO with RTU-DNE T. z Press the fixing clips on top and bottm of Slim DI/DO and check if the connection is fine.

z The colors on the PINs on the DeviceNet connection port match the colors of the connection cables. Make

sure you connect the cable to the right PIN.

z We recommend you also apply Delta’s power module in the connection.

4 How to Configure RTU-DNET

In this section we will introduce how RTU-DNET as a DeviceNet slave realizes the data exchange between

DeviceNet master and DVP Slim DI/DO extension unit.

z DeviceNet master sends the data to Slim DI/DO. z RTU-DENT sends the input data from Slim DI/DO to DeviceNet master.
