Overview

	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.
	• 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.

2-4	Installation

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

ATTENTION: When setting the node address, use a blunt, pointed instrument. Do not use a pencil or pen ! because lead (graphite) or ink may damage the switch

assembly.

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.
