This manual covers the hardware and software installation for configuring DeviceNet
to interface with the Link system. The reader should have the software, RSLogix,
RSNetWorx, RSLinx, and Configuration Editor/DSD installed on the computer and a
working knowledge of the software prior to configuring the DeviceNet interface.
Contact the supplier of the above software if any difficulties are encountered installing
the software installing.

The following hardware is required for DeviceNet set-up and operation:
•L5351 Link card installed in a L5392 or L5300.
•DeviceNet scanner card installed in a PLC.
•a 24VDC Supply (> 1 amp rating)
•A PC running Windows 95/98 or NT

Configuring the L5351 consists of two basic parts. The first is configurating the host
Link module with the definition of “register” function blocks and their and
interconnection with other Link function blocks on the Link fiber-optic ring. The
L5351 appears as an I/O device to the rest of the Link system. The second resides in
the DeviceNet master (such as a PLC DeviceNet Scanner module) and defines the
number and type of parameters to transfer and how to map them to PLC memory.
Each node on the DeviceNet network can transfer a maximum of 127 words. The
L5351 is a node on the network. A maximum of three L5351’s can be inserted into
each L5300 or L5392. Each card is considered a separate node. As a result, the Link
system, using three L5351 LinkCards in one L5300 or L5392, can transfer a
maximum of 381 words. The PLC will be the limiting factor. Allen Bradley’s PLC 5,
using DeviceNet scanner card equipped with two ports, has the maximum capability of
processing 357 words. Allen Bradley’s SLC 500, using DeviceNet scanner card
equipped with one port, has the maximum capability of processing 150 words.

This chapter covers the installation of the L5351 LinkCard in a L5392 LinkStation.
Prior to handling the cards, discharge any static electricity from your person by using
a proper ESD protection kit. If you do not have an ESD kit, touch a panel ground to
discharge any static electricity from your person. Take necessary precautions to
disconnect and lockout any power sources that might be affected while doing this
procedure.
Step 1. Remove the cover
Disconnect power and remove all connections from the L5392 or L5300.
Squeeze the tabs on each side of the L5392 or L5300. This allows you to remove the
plastic cover.
Step 2. Inserting the L5351 Link Card
Insert the L5351 Link Card(s) into the desired slot(s). Slot number 1 is usually
reserved for the L5311 RTNX card. If you do not have a L5311 card in your system
the L5351 can be inserted into any one of the four available slots. Make note of the
slot the L5351 card location.
Step 3. Replace the cover
Replace the cover by inserting the plastic cover until the tabs on the side snap into
place.

This chapter describes the electrical connections to the L5351 LinkCard.
The communications cable should be two-pair, shielded, twisted pairs. The end to end
length and the wire gauge will determine the baud rate used around the network.

The supply voltage to V- and V+ can be supplied locally using an external power
supply or over the network using the PLC power supply. The voltage range is 11 vdc
to 24 vdc. The voltage is generally supplied by the PLC. The LinkCard L5351
current consumption at 24 VDC is 30 mA.

This chapter covers making a simple Link DeviceNet configuration.
The example uses a L5392 with the L5351 was installed in slot J2. The L5311 RTN
card is inserted in slot J1.
Step 1. Select BLOCK :: LINKCARD :: L5351

This inserts the DeviceNet handler block in the configuration. This block is used to
identify the MAC id number, Baud rate, L5351 site location and the order of the
DeviceNet registers.
Note. The order of the registers in the DeviceNet handler must match
the scanner card in the PLC. If the order is does not match
communications between the L5351 card and the PLC will fail.

Step 2. Insert the types of registers you require for your system.
The example configuration has one of each type (Bit,
Unsigned and Signed registers).
