The GEnet Factory LAN architecture is based on standards set forth in the Manufacturing Automation Protocol (MAP) specification. 2 Carrierband Network Interface Features of the LAN Interface Module The features of the GEnet Factory LAN Interface module are described briefly here. For a more complete description see the appropriate GEnet Series Six PLC Network Interface User s Manual. Other related publications are listed on page 7. Direct LAN Attachment to the Carrierband Network The LAN Interface module consists of two boards (controller board and modem board) which plug directly into the Series Six Plus CPU rack. Figure 1 illustrates the LAN Interface module as part of the network. The LAN Interface module connects directly to the Carrierband Network through the 5 Mbps modem board. Intermediate devices such as bridges or gateways are not required, The direct connection provides the high performance required for real-time control applications. The communications software is down-loaded to the LAN Interface and stored in Random Access Memory (RAM). This makes it easy to reconfigure or upgrade the communications software simply by downloading it again. An on-board capacitor provides 72-hour memory retention which will prevent loss of the communication software due to most power loss situations. Carrierband Networks: Networks of up to 72 stations or up to 2000 feet cable span can be constructed using simple do-it-yourself carrierband technology. The 75 ohm coaxial cable plant contains no active (powered) components. Received signal strength limits network size and depends on the number of intervening stations and the cable distance over which the signal must travel. For carrierband cable design, refer to GFK-0014, Carrierband Cable Plant Design and Installation Manual for step-by-step instructions. GEnet carrierband complies with the IEEE 802.4 Phase Coherent standard, operating at 5 Mbps. Communication Services There are three different communication protocols for transferring data on the network: MAP, Datagram, and Global Data. The LAN Interface software for these protocols is offered as two separate software GFK-0015C packages, one for MAP 3.0, and the other for MAP 2.2. Regardless of which MAP version you choose; MAP, Datagram, and Global Data operate simultaneously on the network and within each station. MAP Protocol (7-layer) MAP protocol is defined by the Manufacturing Automation Protocol (MAP) specification. MAP is an approved standard. MAP-compatible products are available from a variety of manufacturers, and their interoperability has been established. The primary service offered by the MAP protocol is reliable message transfer between two interconnected stations. MAP protocol provides automatic error recovery for most kinds of errors. MAP is ideal for transferring large amounts of data between two specific stations, such as PLC program downloads. A feature of MAP is that the two communicating stations need not be on the same LAN, so long as the different LANs are connected by an appropriate intermediate station. MAP commands are directed from an initiating station to a single specific responding station. Each message exchange is explicitly initiated. Datagram Protocol (3-layer, miniMAP, EPA) GEnet Datagram protocol is a subset of the MAP/EPA standard specified in MAP Version 3.0. MAP/EPA represents an optional enhancement of the basic MAP standard, toward improved real-time performance for direct control applications. These applications, in contrast to MAP applications, send short messages but demand very quick response. GEnet Datagram protocol provides basic read and write data transfers between two stations on the same LAN. Like MAP, automatic error recovery is provided. GEnet Datagram commands are directed from an initiating station to a single specific responding station. Each message exchange is explicitly initiated. Global Data Protocol GEnet Global Data protocol is a proprietary innovation of GE Fanuc - NA. Carrierband Network Interface 3 Global Data provides periodic data transfers from a source station to unspecified receiving station(s). Receiving stations elect to receive specific data according to symbolic variable-names, but from unspecified source station(s). The receiving ladder logic program is notified only if the data is not updated in a timely fashion. GEnet Global Data provides highIy efficient transfer of periodic data to one or many stations on the same LAN. Symbolic data references permit independent programming of the stations. A single command initiates the transfer, which then proceeds periodically without further attention by the ladder logic program unless an exception condition occurs. Station Management and Diagnostics Tools The station management and diagnostic tools featured are: GEnet System Manager (GSM) (called Local Management Console or LMC with the MAP 2.2 software) The Local Station Manager (LSM) GEnet System Manager (GSM) GEnet System Manager (GSM) is a software package which runs on an IBM PC or IBM-compatible (e.g., Workmaster) computer. GSM is used to perform the following functions: Create and store configuration files to be downloaded as the communication software to a Series Six PLC LAN Interface. A terminal mode of operation provides access to the local Station Manager of Series Six LAN Interfaces. GSM Software Versions The GEnet System Manager (GSM) comes in two versions: Local and Network. Local GSM comes as part of the MAP software and allows connection from the computer COMMl port to the 9-pin port on the Series Six LAN Interface. Network GSM is an optional software package (purchased separately) which allows GSM to work over the network. The appropriate MAP Interface card is required for the personal computer on which GSM is to be installed. A download server is included with network GSM to load configuration files to Series Six LAN Interfaces over the network. Local Station Manager The Local Station Manager (LSM) is a part of the basic Series Six LAN Interface communication software. The LSM executes as a background activity on the LAN Interface module to provide online supervisory access to it. The LSM can be accessed in three ways: Via the 9-pin serial port to a locally connected user-provided terminal. Via the network from GEnet System Manager. Limited access is also provided directly to the ladder logic program of the associated Series Six PLC. The LSM provides all the following services via the local serial port or over the network to GSM. A subset is available directly to the ladder logic program. An interactive set of commands for interrogating and controlling the LAN Interface module. An online help facility. Unrestricted access to observe internal statistics, an error log, and configuration parameters. Password security for commands that change the LAN Interface states or configuration. Installation The Carrierband LAN Interface Module consists of two boards that plug into two adjacent card-slots in the Series Six Plus PLC. The digital controller board The modem board A separate ribbon cable connects the two boards together. Each board is also shipped with a faceplate. 4 Carrierband Network Interface BOARD OK LED RESET BUTTON DIP SWTTCHES MAC ADDRESS RIBBON CABLE CONNECTOR 3PL CONNECTOR Figure 2. Controller Board Digital Controller Board The digital controller (see Figure 2) connects the LAN Interface to the backplane of the Series Six PLC, allowing data to flow to and from the PLC. It contains RAM storage for LAN communication software which is downloaded to the board using GEnet System Manager (GSM) software. The controller board has the following user-accessible elements: 1. BOARD OK LED This LED is ON if the LAN Interface hardware has passed diagnostics and is operating properly. It is OFF if either the board fails diagnostics or if a hardware problem occurs on an operating board. 2. ONLINE LED The ONLINE LED is ON when the LAN Interface module is periodically receiving the right to transmit on the network, It is BLINKING when the module is transferring data to or from the network. It is OFF when no other stations are connected and communicating, when the network is not communicating due to a disruption of the cable, or when the local station has malfunctioned. 3. 4. STATUS DISPLAY The Status Display is a seven-segment display used to show a diagnostic code during the power-up diagnostics. It is also used to show the status of the station after it is operating. See GEnet Series Six PLC Network Interface User s Manual, for the meaning of codes which may be displayed. RESTART BUTTON Pressing the Restart button forces a reset of the LAN Interface module. This causes the power-up diagnostics to be run and the software on the module to be reset. Any data being transferred by the LAN Interface module at the time of the restart will be lost. The button is used to force a restart of the LAN Interface module after changes have been made to the maintenance switches. The Restart button is inaccessible when the module faceplate is installed. Depending on the ladder logic program in the Series Six PLC, depressing the Reset button when the Series Six RUN/STOP keyswitch is in RUN may result in failure of the LAN Interface backplane diagnostic, 5. OPTION SWITCHES On the exposed edge of the digital controller board is a set of 8 DIP switches which are used to enable various maintenance options. For a complete description of these switches, refer to GEnet Series Six PLC Network Interface User s Manual, Appendix C. Normally, all these switches should be positioned to the right (OPEN). The option switches are inaccessible when the Digital Controller faceplate is installed. 6. SERIAL PORT GFK-0015C NOTE The GSM terminal is connected to this 9-pin port and communication software may be loaded to the module through this port. For pinouts of this port, refer to Table 2. Carrierband Modem Board The modem board (see Figure 3) connects to the digital controller board through the ribbon cable, but does not connect directly to the Series Six PLC s backplane; the modem board s backplane connection provides mechanical support only. The LAN Interface module is connected to the network through the coaxial LAN connector on the modem board. Carrierband Network Interface 5 GFK-001% 1 1 Figure 3.
