GE PACSystems™ RX3i IC695ETM001 Ethernet Interface Module

GE PACSystems™ RX3i IC695ETM001 Ethernet Interface Module

DESCRIPTION

The Ethernet Interface Module, IC695ETM001, connects a PACSystems RX3i controller to  an Ethernet network. It enables the RX3i controller to communicate with other PACSystems  equipment and with Series 90 and VersaMax controllers. The Ethernet Interface provides  TCP/IP communications with other PLCs, host computers running the Host Communications  Toolkit or programmer software, and computers running the TCP/IP version of the  programming software. These communications use the GE Fanuc SRTP and Ethernet  Global Data (EGD) protocols over a four-layer TCP/IP (Internet) stack.

Features of the RX3i Ethernet Interface include:

▪ The Ethernet Interface implements the capabilities of a Class 1 and Class 2 device.  

▪ Full PLC programming and configuration services. Firmware upgrades from the PLC  CPU using the WinLoader software utility. WInLoader is supplied with any updates to  the Ethernet Interface software.  

▪ Periodic data exchange using Ethernet Global Data (EGD).  

▪ EGD Commands to read and write PLC and EGD exchange memory over the network.  

▪ TCP/IP communication services using SRTP.  

▪ Built-in Station Manager for on-line supervisory access to the Ethernet Interface.  Dedicated Station Manager port.  

▪ Two auto-sensing 10Base T / 100Base TX RJ-45 shielded twisted-pair Ethernet ports  for direct connection to either a 10BaseT or 100BaseTX IEEE 802.3 network without an  external transceiver. There is only one interface to the network (only one Ethernet MAC  address and only one IP address).  

▪ Internal network switch with Auto negotiate, Sense, Speed, and crossover detection.  

▪ Recessed Ethernet Restart pushbutton to manually restart the Ethernet firmware  without power cycling the system.  

▪ LEDs: Ethernet OK, LAN OK, Log Empty, individual port activity and speed LEDs.

New Features for this Release

Release 3.00 of the RX3i Ethernet Interface Module provides the following new features and enhancements:

Support for up to 32 SRTP Channels: SRTP (Client) Channels provides communication from PLC to PLC, or from  the PLC to a host application SRTP server, over an Ethernet Network using the SRTP/TCP/IP protocol.  Up to 80 SRTP/TCP connections total, consisting of up to 48 SRTP Server connections and up to 32 Client  Channels.  PACSystems Ethernet Interfaces support the same set of Channel commands as Series 90 Ethernet Interfaces, and  use identical Command Block formats. Please refer to the PACSystems TCP/IP Ethernet Communications Manual,  GFK-2224C or later) for details. Note that specifying a Remote PLC or Host Application SRTP Server by name is not  supported in PACSystems. The Channel Commands are:

Establish Read Channel (2003). Requests that a channel be established between the Local PLC (client) and a  Remote PLC (server) and that data be read from the Remote PLC and transferred to the Local PLC.

Establish Write Channel (2004). Requests that a channel be established between the Local PLC and a Remote  PLC and that data from the Local PLC be transferred to the Remote PLC (read from the client and written to the  server).
Send Information Report (2010). Requests that a specified block of memory within the Local PLC be transferred to  a Host Application SRTP Server (rather than a Remote PLC).

Retrieve Detailed Channel Status (2002). This is a local command: communication occurs only between the Local  PLC and the local Ethernet Interface. It requests that the current Detailed Channel Status Data (DCSD) words  be returned for the specified channel number. The DCSD consists of two words that contain the last channel  status codes that occurred and an active/inactive channel indicator.

Support for Modbus/TCP Server 

Supports Modbus Conformance classes 0, 1, and 2. The Modbus/TCP Server supports up to 16 simultaneous  connections. These connections are not shared with any other applications. Other TCP-based application protocols  such as SRTP Server use a different set of TCP Connections.
