Introduction

E2050 Software/Firmware Architecture

Typical LAN Connections

The E2050 LAN/GPIB Gateway combines hardware and firmware in a single box that provides a network gateway between network-equipped computer systems and GPIB based instruments. The Gateway enables users of I/O applications to obtain measurement data either locally or remotely from GPIB instrumentation. The following figure shows typical LAN connections for an E2050 Gateway.

Introduction

E2050 Software/Firmware Architecture

The Gateway connects the local area network (LAN) from the computer system to the GPIB bus. Network-equipped computer systems that are supported for use with the Gateway include Series 700 workstations and 32-bit PCs. Following the client/server model of computing, the computer system is the

client, and the E2050 LAN/GPIB Gateway acts as the server.

Client System

Thus, I/O applications running on the computer system can transparently interface to GPIB-based instruments over the LAN. Since several computer systems can access the LAN/GPIB Gateway, groups of users can share access to the same GPIB instruments via the Gateway. In addition, existing I/O applications that are supported with the LAN/GPIB Gateway and are designed for GPIB can use the Gateway without modification beyond an address change.

The Gateway and its attached GPIB instruments can be placed anywhere on the network (rather than with a particular controller or server computer system). This includes networks which span different geographic locations, such as when networked computer systems are located at several different sites. Hence, GPIB instruments can be located where they are most convenient for I/O application users.

In addition, you can have more than one LAN/GPIB Gateway on a network, providing “clusters” of GPIB instrumentation at different locations. This further aids users in accessing the instrumentation they need for their specific I/O applications.

Introduction

E2050 Software/Firmware Architecture

Software/Firmware Architecture Overview

Agilent SICL contains the LAN client software needed to access the LAN/GPIB Gateway. Thus, SICL is also provided with the VISA, VEE, and HP BASIC/UX 700 I/O application software products. To use any of these software products with the LAN/GPIB Gateway, you must also install and configure SICL on the client computer system.

Several of these software products support two different LAN networking protocols: the SICL LAN Protocol and the TCP/IP Instrument Protocol. Version A.01.00 or later of the LAN/GPIB Gateway supports the SICL LAN Protocol and VXI-11 (TCP/IP Instrument Protocol). To check your version of the Gateway (and the protocol(s) you can use with the Gateway depending on the software product you have), see Chapter 4.

As shown in the following figure, the client system contains the LAN client software provided with SICL as well as the TCP/IP LAN software needed to access the Gateway. The Gateway contains LAN server and TCP/IP LAN firmware so that it acts as the LAN server.

The LAN client software provided with SICL uses the TCP/IP LAN protocol suite to pass messages between the client system and the server (the E2050 LAN/GPIB Gateway). Therefore, the client sends I/O requests over the network to the server. The server then executes those I/O requests on the appropriate GPIB based instrument(s) connected to the server.

Introduction

E2050 Software/Firmware Architecture

Using Application Software

This section summarizes how the software on a client computer system works with the E2050 LAN/GPIB Gateway to complete I/O application operations on attached GPIB instruments. For more information on how to use your software with the Gateway, see the applicable software documentation as listed in “Related Software Documentation”.

Establishing a Network Connection

Maximum Client Connections

I/O Application Operation

Before trying to perform an I/O application operation on the Gateway’s GPIB interface and the GPIB bus, the LAN client software in the client computer system establishes a network connection to the LAN server (the Gateway). Once the client establishes a connection, the client can begin to send I/O requests to the Gateway.

The Gateway (LAN server) can have multiple clients connected and being serviced at any given time. The maximum number of concurrent client connections depends on memory usage in the Gateway, including the number of clients and the number of current sessions running on those clients. However, at least 8, but not more than 15, client connections can be running concurrently. Thus, if the maximum number of client connections to the Gateway has not been exceeded, the connection is allowed to occur.

Although several instruments can be connected to the Gateway’s GPIB bus, only one I/O application operation can occur on the GPIB bus at any given time. Therefore, once a client’s request begins to execute on the GPIB, all other client requests for operations on the GPIB must wait until the current client request completes. Client requests are serviced in a first come, first served manner, unless they are prohibited by interface or device locks.

Using Locks If a client has a sequence of I/O application operations to perform that

should not be preempted, the client should obtain a lock on the Gateway’s GPIB interface or device. Once the client’s sequence has completed, it should release its lock, allowing other clients access.

Closing a Network Connection

When a client closes a connection, the Gateway frees up the resources allocated to that client, including any locks, pending I/O requests, memory usage, etc. Abnormal termination (for example, the network and/or client goes down) is discussed in Chapter 5.
