Allen Bradley 1203-CN1

Allen Bradley 1203-CN1 Product Introduction

One sentence positioning: This is a ControlNet communication module, belonging to the SCANPort series of external couplers, responsible for establishing an electronic communication bridge between the ControlNet network and SCANPort compatible devices, and can only interface with one SCANPort product at a time.

Product type: ControlNet communication module/SCANPort external coupler
System: SCANPort communication interface system, compatible with SLC 500 series PLC and related ControlNet network architecture
Main model: 1203-CN1

Allen Bradley 1203-CN1

Core functions:

As an electronic communication interface between the ControlNet network and SCAnport products
Provide redundant media, unplanned message delivery, and deterministic I/O control
Realize data exchange with SCANPort compatible devices through Scanport connection
Interface configuration:

Scan Port: Connect SCANPort devices through a scan port cable and a standard 8-pin circular mini DIN scan port connector
Serial port: 1 RS-232 serial communication port
Network port: 1 ControlNet network access port
Installation method: equipped with DIN rail mounting slot, can be clamped onto the DIN rail base
Electrical parameters:

Supply voltage: 250V DC
Power consumption: 24 mA (at 250V DC)
Status indication:

Two tone LED indicator light, providing three types of status updates:
SCANPort connection status
ControlNet media channel status
Module’s own operating status
Important operational requirements:

The node address of the communication module must be set before the first power on
The node address must be set using tools with blunt dots, and the use of pencils or pens is strictly prohibited as graphite or ink may damage the ESD sensitive components inside the controller
Components sensitive to electrostatic discharge (ESD) are used inside the module, and electrostatic protection measures must be taken during installation, testing, use, or maintenance, otherwise the controller may be damaged
Physics and Installation:

Installation method: DIN rail card mounting
Supports online replacement, does not support hot standby
The module is made of ESD sensitive components and must strictly comply with anti-static operation specifications
Current status: This model belongs to the early SCAnport/ControlNet communication module, which is currently circulating in the market in the form of inventory spare parts and is gradually being replaced by the new generation of communication modules. If necessary, it is recommended to confirm compatibility with existing ControlNet networks and SCANPort devices, and refer to the physical nameplate data of the module for accuracy.
