General Information
1.1 INTRODUCTION
This section provides a description and specications for ICS's Model 9009
and 9099 Ethernet to Modbus Interfaces. All specications and functional
descriptions apply to both units unless otherwise stated.
1.2 DESCRIPTION
The Model 9009 and 9099 Ethernet to Modbus Interfaces provide a user with
multiple ways to control Modbus RTU slave devices with RS-232 and RS-422/
RS-485 signals. The Model 9009 is a PC board assembly with an Ethernet,
GPIB and USB user interfaces. The Model 9099 is an enclosed unit that has
an Ethernet user interface. Both units have a 9-pin connector with user se-
lected RS-232 or RS-422/RS-485 signals for controlling Modbus RTU slave
devices.
In both units, the Ethernet Interface provides a user with multiple protocols
and conversion capability to control serial Modbus RTU devices. The Ethernet
Interfaces support the VXI-11, raw-socket and Modbus TCP/IP conversion and
include a webserver with HTML control pages for the more popular tempera-
ture controllers.
The VXI-11 and raw-socket protocols let the user send simple commands
with ASCII values over a 10/100 Mbs TCP/IP network to control and query
Modbus slave devices. The simple commands are converted into the Modbus
RTU messages and the CRC checksum is added 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 9099 is next addressed to talk.

The 9099 contains a number of advanced features that increase its exibility
and simplies their use in test system applications. The 9099 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 GPIB, USB and
serial conguration, 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.
ModbusTCP/IPpackets are automatically converted into Modbus RTU packets.
The Modbus conversion is transparent and the 9099 does not restrict the Modbus
addresses, functions or data but they are restricted by the capabilities of the
slave device. Response data from the slave device is returned to the sender
as a TCP/IP response packet. Message length is limited to 255 bytes.
The 9099 contains a webserver which provides the user with several types
of webpages. The Welcome page displays information about the 9099 and
displays its status. The Conguration Page provides a way to view the 9099's
current settings and to change the network, serial and USB settings. There
is some overlap with the SCPI setup commands. A rear panel 'LAN Reset'
button allows the user to return the 9099 to its default network settings. Two
Temperature Controller pages and a general Control page let a user view and
control different processes and devices run by temperature controllers.
The 9009's GPIB and USB Interfaces access the 9009's parser as does the
Ethernet interface and use the same simple commands to control and query
Modbus slave devices as does the Ethernet interface. The GPIB interface is
fully IEEE-488.2 compliant. The USB Interface uses Microsoft's Virtual COM
port driver for easy communication with the 9009.
The 9009 and 9099 are VXI-11.3 compliant, can be used in systems with LXI
devices and can be found with the LXI 'VXI-11 Discovery Method'.
The Model 9009 is a 5.5 x 5.5 inch PC board assembly that can be mounted on
the rear panel or inside a host chassis. It accepts 5 to 15 Vdc power.
The Model 9099 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 se-
rial connectors, LAN Reset button and a DC power jack. The 9099 accepts
a wide range of DC voltages and is shipped with an universal power adapter
and plugs.

1.4. VXI-11 CONFORMANCE
The 9099 complies with the VXI-11.3 Specication.
1.4.1 RPC Protocol
The RPC protocol conforms to ONC RPC Version 2.
1.4.2 Sockets
The 9099's VXI-11 service supports 15 TCP/IP sockets for client communica-
tion with a maximum of 4 active sockets. 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 andAbort channels each use
a socket connection. 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 9099 supports 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 9099 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 9099 supports all VXI-11.3 functions including:
create_link destroy_link create_intr_channel destroy_intr_channel
device_lock device_unlock device_abort
device_read device_write device_clear device_trigger
device_remote device_local device_readstb create_intr_channel
device_intr_SRQ device_enable_SRQ

1.5.7 Protocols
TCP/IP for VXI-11, HTTP and RPC communication
UPD and TCP/IP for RPC Port Mapper commands
Modbus TCP/IP for Modbus RTU conversion
Raw Socket for telnet compatible IP packet communication
1.5.8 Raw Socket
The 90x9's Raw Socket conguration is set to the following values:
Port 23
Sockets 4
Echo Off
Prompt None
Timeout 120 seconds xed
Logon message Message equal to *IDN? response.
Terminator Linefeed character
Carriage Returns Client generated carriage returns are ignored.
Backspace Prior character deleted up to the start of the buffer.
Echo On command Cntl-E
Echo off command Cntl-F
The Raw Socket connection will be closed if there is no communication for 120
seconds. To prevent the Raw Socket from timing out and disconnecting, the
client can issue a no change message like space-backspace or a Cntl-E-Cntl-F
sequence, on an occasional basis, to restart the timeout counter.
If Echo was enabled, all client character will be echoed back to the client. The
echo sequence for a backspace is a BS-space-BS to visually wipe the deleted
character off of the telnet client screen.

1.11 INDICATORS
The 9099 has eight LED indicators that 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. Off when
IP address has unexpectedly changed.
ACT Indicates messages are being transferred between the unit
and the LAN.
RDY Indicates the unit has passed self test.
Blinks when all 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 unit 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 unit 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 any of the ESR Register error bits
2 thru 6 are set or LAN ip address unexpectedly changed.
When the unit is turned on, it performs an internal selftest and startup which
takes about 7 seconds. Only the PWR LED is on during the self test-startup
time.
The Model 9009 blinks is GPIB address as a binary value during the self test.
The bit weights are:
RDY TALK LSTN SRQ ERR
16 8 4 2 1
At the end of a successful selftest, the unit turns the RDY LED on after the
outputs have been congured. At this time the LAN and ACT LEDs display the
unit's network status. LAN communication is immediate for static IP addresses.
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.
