About This Manual

WARNING
This manual provides information needed to install and use the Rice Lake Weighing

Systems EtherNet/IP
™
Interface. The EtherNet/IP Interface allows the indicator to
communicate with an EtherNet/IP network. See the indicator installation manual for additional installation information and
detailed descriptions of indicator functions. The EtherNet/IP Interface is installed inside the indicator enclosure. Installation in
NEMA 4X stainless steel enclosures permits use in washdown environments.
Some procedures described in this manual require work inside the indicator enclosure. These procedures are to be performed by qualified service personnel only.
The Ethernet card should NOT be used to communicate between buildings. The Ethernet port is not suitable for connection to circuits used outside the building and is subject to lightning or power faults.
Authorized distributors and their employees can view or download this manual from the Rice Lake Weighing Systems distributor site at www.rlws.com.

1.0 Introduction

EtherNet/IP (“Ethernet Industrial Protocol”) is an open industrial networking standard that allows control applications to make use of widely-available Ethernet communications components and physical media. EtherNet/IP is based on the IEEE
802.3 Ethernet standard, the TCP/IP protocol suite, and CIP Protocol), the real-time I/O and information protocol used by both DeviceNet

networks.
The EtherNet/IP Interface returns weight and status inform ation from an indicator to the network and provides limited control of indicator functions to the programmer. Indicator configuration and calibration cannot be performed through the EtherNet/IP Interface.

2.0 Installation

WARNING
CAUTION
EtherNet/IP-specific functions are provided by an EtherNet/IP module. The module plugs into an open option card slot on the CPU board and provides power and access from the indicator bus to the EtherNet/IP Interface module.
This section describes the procedures used to install the EtherNet/IP Interface into the indicator.

2.1 Installing the EtherNet/IP Interface

Figure 2-1. EtherNet/IP Interface Kit
Disconnect power before removing indicator backplate.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the indicator enclosure.
1. Disconnect indicator from power source.
2. Unplug all connectors from the back of the controller assembly.

Note
3. Rotate left and right hooks away from the DIN rail clip.
4. Carefully remove the controller box from the DIN rail.
5. Disconnect the display cable harness.
6. Loosen the four corner screws and carefully pull the backplate straight out from the enclosure. The boards are still connected to the backplate and will slide out of the enclosure.
All boards will slide out together, the power supply board and the CPU board are connected by a cable.

7. Remove the cable connecting the boards.
8. Remove the power board and CPU board from the back plate by loosening the screws holding them in place.
Installation 3
Retain the screws for installing boards to new backplate. Discard

9. Install the option card on the CPU board standoffs, plugging it into the J8 connector on the CPU board.
10. Secure with option card screws.
11. Connect the CPU board and the power supply board to the new backplat e.

13. Slide the module in to the slot provided until it connects to the option card, the notches on the bottom of the module must slide over the front of the card.
A slight pressure may need to be applied to the top of the module to ensure the notches slide onto the card.

15. Slide backplate with boards into enclosure, ensure that each board is seated correctly in the grooves of the enclosure.
Ensure the enclosure is in the upright position, otherwise the connector for the display will not align with the front cutcut. The DIN Rail clips will be at the bottom.

16. Reassembly control box to the DIN rail.
17. Reconnect all connectors to the back of the controller assembly.
18. Reconnect power to the indicator.
The indicator automatically recognizes all installed option cards when the unit is powered on. No hardware-specific c onfiguration is required to identify the newly­installed card to the system.
