Chapter 1 provides an overview of your 1203-CN1 ControlNet
communications module. It provides the following information:
•Description of how the 1203-CN1 module works.
•Overview of ControlNet.
•Overview of SCANport products.
•Parts of the 1203-CN1 module.
•Overview of setting up the module.
•Required equipment and tools.
The 1203-CN1 ControlNet communications module provides an
electronic communications interface between a ControlNet network
and any single SCANport product.

ControlNet
A SCANport cable connects the module to a SCANport product
through a SCANport interface port on the SCANport product. One or
two ControlNet cable taps connect the module to the ControlNet bus,
depending on whether you are using non-redundant or redundant
connections.
Publication 1203-5.13 – February, 2002
1-2Overview
The module translates the ControlNet messages into SCANport
messages that can be understood by the SCANport product. Both
scheduled I/O data and unscheduled messages can be transferred
through the module. ControlNet capability enhances the functionality
and usefulness of the connected product and lets you communicate
with the SCANport product from any node on the ControlNet
network.
What Is ControlNet?
ControlNet is a real-time, control-layer network providing high-speed
transport of both scheduled time-critical I/O data and unscheduled
messaging data, including upload/download of programming and
configuration data and peer-to-peer messaging, on a single physical
media link. Deterministic and repeatable, ControlNet’s high-speed (5
Mbps) control and data capabilities significantly enhance the size and
speed of I/O data and messaging data transfers.
Specifically, ControlNet provides:
•Bandwidth for I/O, real-time interlocking, peer-to-peer
messaging and programming—all on the same link, without
impacting time-critical I/O.
•Deterministic, repeatable performance for both discrete and
process applications.
•Multicast of both inputs and peer-to-peer data.
•Fiber media, media redundancy and intrinsically safe options.
•Simple and flexible installation requiring no special tools to
install or tune the network.
•Network access for any node.
Publication 1203-5.13 – February, 2002
•Support for up to 99 nodes per subnet to help flatten architectures
and support more distributed systems.
•User-configured real-time remote analog updates for more
flexibility and process capabilities.

Installing Your 1203-CN1 Module
The following instructions explain how to physically install your
1203-CN1 module.
Important: To guard against device malfunction, you must wear a
grounding wrist strap when installing the 1203-CN1 module.
1. Set the module’s ControlNet node address by clicking the + or button to the desired value for each digit.
Important: Each node on the ControlNet network must have a
unique address.
Important: The node address must be set before power is applied
because the module uses the node address it detects when it first
receives power. To change a node address, you must set the new value
and then remove and reapply power to or reset the module.
Figure 2.1
Setting the Module’s Node Address
Publication 1203-5.13 – February, 2002
ATTENTION: When setting the node address, use a
blunt, pointed instrument. Do not use a pencil or pen
!
2. Ensure the DIN rail to which the module will be attached is
connected to an earth ground.
Important: If EMC compliance is required, the DIN rail should be
properly grounded inside a full metal enclosure. The enclosure should
also be properly connected to an earth ground.
because lead (graphite) or ink may damage the switch
assembly.

3. Hook the top lip of the module’s DIN rail mount onto the top of
the DIN rail and then rotate the module onto the DIN rail. You
will hear the module snap into a locked position.
Figure 2.2
Connecting the Module to the DIN Rail
4. Verify the module is correctly grounded to the DIN rail by using
an Ohm meter to measure between:
• DIN rail’s earth ground.
• Metal shell in the module’s RS-232 serial port.
If the reading is greater than 2 Ohms, you must reconnect the
module to the DIN rail, making sure it attaches securely.

5. Connect the SCANport cable to the SCANport product and the
module.
To connect the cable to the module, align the pins on the cable
with the holes in the SCANport connection and then insert the
SCANport cable. The cable will click into a locked position.

The module is now physically installed. Its SCANport and
ControlNet LEDs are solid green, and its Module LED is flashing
green. (If your module’s LEDs differ, refer to Chapter 7,
Troubleshooting, for troubleshooting information.)
The flashing green Module LED means that the module is not yet
able to provide an interface between the ControlNet network and the
SCANport product. For it to do so, you must:
1. Configure, if necessary, the module by editing its parameters.
Refer to Chapter 3, Getting Started.
2. Configure the controller on the ControlNet network to recognize
and communicate with the module. Refer to Chapter 4,
Configuring a Controller to Communicate with the 1203-CN1
Module.
3. If desired, write a PLC Ladder Logic program to control the
SCANport product. Refer to Chapter 5, PLC Ladder Logic Programming.
Important: The 1203-CN1 ControlNet communications module will
not communicate over ControlNet without being connected to a
SCANport product which is powered and operational.

Removing the 1203-CN1 Module
If you want to remove the 1203-CN1 module, you need to:
Important: To guard against device malfunction, you must wear a
grounding wrist strap when removing the 1203-CN1 module.
1. Turn off the power supply to the module.
2. Disconnect all cables and the power supply from the module.
Important: To disconnect the SCANport cable, gently push in the
cable and then pull it out.
3. With a screw driver in the tab release, gently push its handle
towards the module to release the connection tab, and then pull
the module off of the DIN Rail.
