This model includes the ability to program the processor with 984 Ladder Logic program editor available with the Concept and ProWORX programming software packages. This programming capability allows the Momentum processor to be applied in a wide range of control application from simple machine control to batch process control. Embedded The Momentum 171 CCC 980 20 Processor’s Ethernet Communication Ethernet Port is a standard 10 baseT connection and supports Modbus TCP/IP protocol that includes services such as the reading and writing of discrete data, diagnostics, and registers, along with on-line programming and full program upload/download capability. This enables the M1E processors to be used in control applications that include data acquisition, peer-to-peer communications between multiple M1E’s and I/O scanning, using the same communication backbone that is used in the business-level systems: Ethernet Web Page The Momentum 171 CCC 980 20 Processor includes an embedded Web Capabilities Server with 5 built in web pages that include the following pages. These embedded web pages report real time information on the Momentum’s processor status and the local I/O module points. These pages are easily accessible with any PC configured with only a standard web browser, without the need for any custom configured displays. • Home Page – link to other web pages • Controller Configuration - contains system information • Ethernet Statistics – monitors Ethernet receive/transmit statistics • Momentum I/O Status Page – including status, attributes, versions, and part number information. • Support Page – provides support contact information at the Schneider Web Sites and an E mail address for product feedback Continued on next page Schneider Automation All Rights Reserved Page 2 Document: 171CCC98020- data sheet.doc Author: Joe Benedetto, Date: 25 August 2003 Momentum 171 CCC 980 20 Processor, Continued Technical The following are the technical specifications Specifications Product Specifications Central Processor Unit 186 based Clock Speed 50 MHz IEC Program Logic Memory Capacity 18 K Words Register Memory 26,032 Registers I/O Capacity – total 8192 input points/ 8192 output points Number of I/O modules Local I/O 1 module Ethernet port 64 modules Communication Port 1 Ethernet Protocol MODBUS TCP/IP Communication Rate 10M bits per second Connector Single RJ-45 connector (shielded or unshielded) Media Category 5 or better, twisted pair, shielded cable Error Checking CRC-32 Error Check Error and Fail States Safe I/O mode Addressing Unique IEEE Global (MAC) Address User assigned IP Address Mode of Operation Master Slave Topology Star, Multi-Drop Communication Port 2 RS-485 Protocol Modbus Communication Rate 19,200 baud Connector 9 pin DB connector Media Two or four wire connection Error Checking CRC-16 Error Check Mode of Operation Master – Slave Topology Multi-drop Continued on next page Schneider Automation All Rights Reserved Page 3 Document: 171CCC98020- data sheet.doc Author: Joe Benedetto, Date: 25 August 2003 Momentum 171 CCC 980 20 Processor, Continued Environmental Specifications Storage temperature -40°C to 85°C Operating temperature 0°C to 60°C Humidity (Non-operating) 95% Rh @ 60°C, Non-condensing, 96 hours (Operating) 95% Rh @ 60 C, Non-condensing, 24 hours Altitude (Non-operating) Up to 15,000 ft.
