General Information
1.1 INTRODUCTION
This section provides a description and specifications for ICS's Model 8099
Ethernet to Modbus Interface. All specifications and functional descriptions
apply to all units unless otherwise stated.
1.2 DESCRIPTION
The Model 8099 Ethernet to Modbus Interface is a VXI-11.3 compliant in-
terface that provides RS-232 and RS-422/RS485 serial interfaces to control
Modbus devices using the Modbus RTU protocol. It lets the user send simple
commands with ASCII values over a 10/100 Mbs TCP/IP network to control
and query Modbus slave devices. The 8099 converts these simple commands
into the Modbus RTU packet protocol and adds the CRC checksum to make
a complete Modbus RTU packet. The Modbus RTU packets are sent serially
over a RS-232 link to a single Modbus slave device or over a RS-485 network
to one or multiple Modbus devices. Responses are checked and valid response
data from a query is returned when the 8099 is next addressed to talk.
The 8099 contains a number of advanced features that increase its flexibility
and simplifies their use in system applications. It is an IEEE-488.2 compatible
interface with an expanded Status Reporting Structure that complies with the
SCPI standard. SCPI commands are used to set the serial configuration, and
to enable bits in the Status Reporting Structure to generate Service Requests.
The user can also enter his own IDN message to personalize the unit as part
of his assembly. The 8099 contains a webserver which allows the user to
view and update the 8099's configuration settings. All settings are saved in
nonvolatile memory.

The 8099 is VXI-11.3 compliant which makes it easily controllable from virtu-
ally any computer with network access. One programming method is to make
program calls to a VISA or SICL library which can communicate with VXI-
11.3 instruments. LabView and VEE are graphical applications that can make
VISA calls. SICL or VISA calls are recommended for Visual Basic, C and other
program languages that can call any library. Another programming technique
is to use the RPC protocol to communicate with the 8099. The RPC protocol
makes it easy to control the 8099 from any LINUX/UNIX like environment.
JAVA programming examples are available on SourceForge.
The module contains a single instrument personality, inst0. inst0 is an IEEE-
488.2 compatible instrument and lets the user access the internal parser and
execute modbus commands to control the slave Modbus devices. The Ethernet
IP settings can be accessed by a web browser or by ICS's VXI-11 Configure
utility program. A 'LAN Reset' button allows the user to return the card to its
default IP settings at any time.
At power turn-on, the module's boot up and internal selftest process typically
takes approximately 4 seconds. At the end of the selftest, the 8099 turns the
RDY LED on if the test was successful. The LAN and ACT LEDs show the
status of the network connection. The TALK, LSTN and SRQ LEDs show
the module's current address status and if it has asserted a Service Request.
The ERR LED is momentarily illuminated when the card senses a soft error
condition or has a problem with a command that it received.
The 8099 conforms to the requirements for a LXI class C instrument per LXI
Standard Rev 1.1 with the exception of no support for auto-IP configuration. The
8064 exceeds the LXI specification for a class C instrument because it is fully
IEEE-488.2 compliant and specifies complete use of the VXI-11 protocol.
The Model 8099 is packaged in a small Minibox™ metal case that is less than
1U in height (1.6 inches) The front panel contains the power switch and LEDs
which indicate the unit's status. The rear panel contains the Ethernet and serial
connectors and a DC power jack. The 8099 accepts a wide range of DC volt-
ages and is shipped with an adapter for the local power lines.

1.4. VXI-11 CONFORMANCE
The 8099 is a TCP/IP-IEEE 488.2 Instrument and complies with the VXI-11.3
Specification.
1.4.1 RPC Protocol
The RPC protocol conforms to ONC RPC Version 2.
1.4.2 Sockets
The 8099's VXI-11 service supports 15 TCP/IP sockets for client communica-
tion. The sockets are normally opened and closed by the clients. The unit will
close the socket and release all resources if a broken connection is detected or
when the link count goes to zero if Auto Disconnect is enabled.
There is a separate socket for UDP RPC Port Mapper communication.
1.4.3 Channels
Supports Core, Abort and Interrupt channels. Core and Abort channels each
use a socket connection. Core channels support up to 64 device links and locks.
A reverse Interrupt channel is a TCP/IP socket connection that does not count
against the 15 client communication sockets limit.
1.4.4 Device Links and Locks
The 8099 support a maximum of 64 device links and 64 locks that can be used
over multiple Core channels by one or more clients.
1.4.5 VXI-11 Interface Name
The 8064 has only one instrument personality and the default name is inst0.
The name may be changed to any 8 character string.
1.4.6 VXI-11.3 Supported Functions
The 8099 supports all VXI-11.3 functions including:
create_link destroy_link create_intr_channel destroy_intr_channel
device_lock device_unlock device_abort

1.9 INDICATORS
The 8099 has eight front panel LEDs that normally display the following
conditions:
PWR Indicates power on
LAN Indicates that the unit is ready and is connected to an active
LAN. Blinks at user request to identify the unit.
ACT Indicates messages are being transferred between the unit
and the LAN.
RDY Indicates the unit has passed self test.
Blinks when all 8099 sockets are used and the unit cannot
open a new socket or link.
TALK Indicates the unit was sent a device_read command
LSTN Indicates the unit was sent a device_write command.
SRQ On when the card is requesting service. When a reverse
Interrupt channel is established and Service requests are
enabled, the SRQ LED will blink momentarily to indicate
that the card has sent an service request message to the host
application.
ERR Blinks on when the unit has detected a soft error condition
such as a command error, device error or a communication
problem. Steady on when ESR Register error bits 5, 4 or 2
are set.
When the unit is turned on, it performs an internal selftest and startup which
takes about 4 seconds. Only the PWR LED is on during the self test-startup
time.
At the end of a successful selftest, the unit turns the RDY LED on after the
outputs have been configured. At this time the LAN and ACT LEDs display
the card's network status. LAN communication is immediate for static IP ad-
dresses. DHCP IP address assignment times add to the LAN startup time.
If the unit detects a hard self test error, it blinks the error code on its front panel
LEDs. Refer to paragraph 5.4 for a description of the selftest errors and their
possible causes.
