INSTALLATION
WIRING
Mount the ToolLink Gateway on a horizontal or vertical
surface, in a suitable location or enclosure for your
application. Provide sufficient clearance and airflow to
maintain 0°C to 70°C ambient operating temperature
range. Fasten the ToolLink Gateway to the mounting
surface using two screws (not provided) in the 0.19 inch
mounting holes.
All dimensions are inches
The ToolLink Gateway requires two connections – one to the
DeviceNet network (male 5-pin micro connector) and one to the
serial device (male DB9 connector). DeviceNet and serial cables
are available from a variety of industrial sources. Follow all
applicable electrical codes in your area when mounting and wiring
any electrical device.

All power is received from the DeviceNet network. The ToolLink
Gateway draws up to 200mA from the 24VDC power supply.
Select your DeviceNet cables and power supply so that it can
provide sufficient current for all networked devices at their peak
operating power.
The following are typical ToolLink Gateway wiring examples. Your
RS232 or RS485 interface may vary. Refer to your device’s
documentation for the required data and control signals.

Each rotary switch parameter has a PGM option. Setting a
switch to PGM allows the parameter to be remotely set over
DeviceNet. However, it must first be initialized. To initialize,
set the switch to desired value and power up the gateway.
The new settings are saved in its memory. Power down and
change switch to PGM mode.

When in Timeout mode, the ToolLink Gateway waits for an inter-byte delay to signal the end of a
message packet. If the receiver is idle for more than 3.5 byte times (or 5 msec, whichever value is
greater), then all bytes received before the timeout are grouped into a single message packet. 1 byte
time = 10 bits ÷ baud rate.
When in Length mode, the ToolLink Gateway receives a fixed number of bytes as a complete message
packet. The Maximum Receive Size parameter defines the message packet size (0 to 64 bytes) for the
LENGTH mode.
When in delimiter mode, the ToolLink Gateway uses start and stop delimiter strings to identify the
beginning and end of a message packet. The Start Delimiter String parameter defines the beginning of
a message, and the Stop Delimiter String parameter defines the end of a message.

Chapter 2 – Quick Start Guide
This chapter describes the setup for a simple gateway solution using a DeviceNet master and the serial
port of a PC using HyperTerminal. Before beginning a basic understanding of DeviceNet and rs232 is
required. Experience using explicit and poll transactions from the software provided with your DeviceNet
master is essential. For more information on generating explicit and poll messages consult the DeviceNet
master’s software user’s guide.

Chapter 3 – Theory of Operation
This chapter describes how the CDN466 gateway operates. You should have a working knowledge of
DeviceNet and asynchronous serial communications before continuing. The Open DeviceNet Vendors
Association (www.odva.com) is a good source for general DeviceNet information. Refer to your serial
device documentation for its protocol information.
DeviceNet Interface
The DeviceNet Specification defines an Object Model that consists of Objects and Attributes. An Object
is a predefined software process, and an Object Attribute is a data value used or created by that process.
An Object can have multiple Instances, or the same process operating with different sets of Attributes or
data values. For the purpose of this document, an Object Instance is an independent program or
process, and its Attributes are configuration parameters and data values that are unique to that specific
Object Instance.
The CDN466 gateway has six different Object Classes, or types. Five are standard objects defined by
the DeviceNet Specification (Identity, Router, DeviceNet, Assembly, Connection). One specific object
defines for the CDN466 gateway (Serial Stream). The Serial Stream Object configures the serial channel,
and scans the incoming serial stream for valid message packets
The CDN466 gateway operates as a DeviceNet slave. It supports Explicit Messages and Polled I/O
Messages of the predefined master/slave connection set. The Explicit Unconnected Message Manager
(UCMM) is not supported. The CDN466 will be a Group 2 Only Slave device. It will support Change-ofState and Polled I/O Messages. It will also support Explicit Messaging. The DeviceNet interface will
comply with the DeviceNet Physical Layer specification.
The I/O Messaging process consists of the DeviceNet master sending output data to the CDN466 in the
form of a Poll/COS Command Message, and the CDN466 returning input data to the DeviceNet master in
a Poll/COS Response Message. The difference between Poll and Change-of-State is Polled I/O
Messaging is initiated by the DeviceNet master and responded to by the slave device
The output and input data bytes are typically mapped into data files inside the DeviceNet master. These
data files are exchanged with the user application program, which acts upon the received input data and
writes new output data to the DeviceNet master.

The first 4 output data bytes received from the DeviceNet master contain used to control and monitor the
flow of data through the gateway. The remaining output data bytes contain serial message data to be
transmitted out the serial channel.
The ToolLink Gateway can receive serial message packets up to 68 bytes long. Set the Maximum
Receive Size equal to the size of the largest receive message packet for your application. This
parameter defines the Data Field size (M) for the input bytes.

Serial Interface
The Serial Stream Object attributes configure the serial channel’s baud rate, number of data bits and stop
bits, parity, and flow control. This configuration applies to both the serial transmitter and receiver. The
gateway has separate 128-byte serial transmit and receive FIFO buffers, allowing full duplex operation
when supported by the physical layer media.
The Serial Stream Object is also used to configure the message packet format. A message packet is
determined by one of three modes. List mode searches for Pre-Delimiter and Post-Delimiter byte strings
at the beginning and end of a message. Length mode captures a specific number of message bytes,
defined by Packet Length. Timeout mode uses an inter-byte delay (Packet Timeout) to signal the end of
a message. The following examples show the three Serial Stream Object Delimiter modes.
When the Receive Mode is set to List, the ToolLink Gateway uses start and stop delimiter strings to
identify the beginning and end of a message packet. The Start Delimiter String attribute defines the
beginning of a message, and the Stop Delimiter String attribute defines the end of a message.
The Start Delimiter String attribute format is [length][byte1][byte2][byte3][byte4]. The length byte is 0 to
4. The remaining byte(s) define the start of a message packet, which must be a unique byte string that is
not used elsewhere in the message packet. The ToolLink Gateway monitors received bytes for a match
to the Start Delimiter byte string. When a match is found, the start delimiter byte(s) and all subsequent
bytes are saved in the RX buffer, until a Stop Delimiter byte string is received. If the Start Delimiter String
is null (length = 0), the gateway starts saving the first received byte in the RX buffer.
The Stop Delimiter String attribute format is [length][byte1][byte2][byte3][byte4]. The length byte is 0 to
4. The remaining byte(s) define the end of a message packet, which must be a unique byte string that is
not used elsewhere in the message packet. Once a Start Delimiter String is received, the ToolLink
Gateway monitors the received bytes for a match to the Stop Delimiter byte string. When a match is
found, the gateway saves the stop delimiter bytes and the message packet is complete. If the Stop
Delimiter String is null (length = 0), then the gateway saves the start delimiter bytes and all subsequent
bytes until the Maximum Receive Number of bytes are received. This is a modified version of the
Length Mode, using a start message delimiter to signal the start of a new fixed length message packet.
When Receive Mode = TIMEOUT, the ToolLink Gateway waits for an inter-byte delay to signal the end of
a message packet. If the receiver is idle for more than 3.5 byte times (or 5 msec, whichever value is
greater), then all bytes received before the timeout are grouped into a single message packet.
MKS Instruments, Inc.

ToolLink Instruction Manual Rev 1.0
1 byte time = 10 bits ÷ baud rate.
When Receive Mode = LENGTH, the ToolLink Gateway receives a fixed number of bytes as a complete
message packet. The Maximum Receive Size parameter defines the message packet size (0 to 64
bytes) for the LENGTH mode.
Serial Synchronization
The RX Handshake Enable parameter selects the Receive Synchronization option. The Receive
Counter (RXCTR) input byte and Receive Acknowledge (RXACK) output byte provide a handshake
between the ToolLink Gateway and application program. The ToolLink Gateway always increments
RXCTR (1-255) when it loads a new RX message packet into the input Data Field. When Receive
Synchronization is enabled, the application must set RXACK = RXCTR to acknowledge receipt of an RX
message, before the ToolLink Gateway will load the next RX message into the input Data Field. A ladder
logic algorithm for Receive Synchronization is shown below.
RXCTR <> RXACK?
SAVE NEW RX MSG
RXACK = RXCTR
The TX Handshake Enable parameter selects the Transmit Synchronization option. The Transmit
Counter (TXCTR) output byte and Transmit Acknowledge (TXACK) input byte provide a handshake
between the ToolLink Gateway and application program. When Transmit Synchronization is enabled, the
application must increment TXCTR (1-255) when is loads a new TX message packet into the output Data
Field. The ToolLink Gateway sets TXACK = TXCTR after it loads the message into the TX buffer. The
application should wait for the acknowledgement before sending a new TX message, to ensure no data is
lost. A ladder logic algorithm for Transmit Synchronization is shown below.
TXACK == TXCTR?
LOAD NEW TX MSG
TXCTR = TXCTR+1

Chapter 4 – Gateway Configuration
This chapter describes how to configure and operate the CDN466 gateway. Reading and writing attribute
values over its DeviceNet interface configure the gateway. There are a variety of DeviceNet configuration
tools available. Simple configuration tools use GET_ATTRIBUTE and SET_ATTRIBUTE explicit
message commands to read and write attribute values, addressing each attribute by its Object, Instance,
and Attribute numbers. This information is contained in Chapter 5. More sophisticated configuration tools
use EDS files to simplify attribute configuration. You can configure the gateway using pull-down menus,
buttons, and data entry fields from the gateway’s Electronic Data sheet (EDS) file.
Configure DeviceNet Interface
The DeviceNet Baud Rate and MAC ID Address are set using the rotary switches. Configure switches
before connecting to the DeviceNet network. There is either a small triangular indicator or white indicator
on the switch. Use a small screwdriver to align that indicator with the desired setting. Remove the
CDN466 cover if necessary to access the rotary switches.
DeviceNet Baud Rate Switch
Valid settings are 125K, 250K, 500K, or PGM. When PGM is selected, the CDN466 uses the baud rate
saved in its retentive memory. To save a valid baud rate in memory, set the switch to the desired baud
rate and power up the CDN466 for a few seconds. Power down and set the switch to PGM. You may
also write to the DeviceNet Object Baud Rate attribute.

MAC ID Switches
The two MAC ID switches represent decimal numbers from 00 to 99. The LSB switch selects the Ones
digit and the MSB switch selects the Tens digit. Valid MAC IDs are 00 to 63. Setting a MAC ID address
greater than 63 forces the gateway to use the MAC ID saved in retentive memory. To save a valid MAC
ID in memory, set the switches to the desired MAC ID and power up the CDN466 for a few seconds.
Power down and set the switches to value greater than 63. You may also write to the DeviceNet Object
MAC ID attribute.

Register EDS File
If using a DeviceNet configuration tool that supports Electronic Data Sheet (EDS) files, you should now
register the gateway’s EDS file with the software. The latest EDS file versions can be downloaded from
www.mksinst.com. Select the EDS file that matches your gateway’s part number and firmware version.
Follow your configuration tool instructions to register EDS file. The parameters in the EDS file correspond
with the Serial Stream Object attributes defined in Chapter 5.

Rx Counter
Byte 1
TX Acknowledge
Byte 2
Length
Byte 3
Data
Max Rx Bytes
Status: Returns the state of the serial buffers and indicates if a parity error was found in the received
data. Status is bit-mapped as follows:
Bit 7 – RX Buffer Empty
Bit 6 – RX Buffer Overflow
Bit 5 – RX Parity Error
Bit 4 – TX Buffer Empty
Bit 3 – TX Buffer Overflow
Rx Counter: Increments from 0-255 each time a new serial packet received by the CDN466 is placed in
the Data field.
TX Acknowledge: Increments from 0-255 each time a complete serial message has been transmitted by
the CDN66.
Length: The number of bytes of the serial message in the Data field.
Data: Data received by the CDN466 from the serial connection, unused bytes are set to 0.
Transmit Data – Attribute 4
Setting the Transmit Data attribute will allow data to be sent to the serial connection, as in the I/O
command message. The Transmit Data attribute is formatted as follows:
Command
Byte 0
Rx Acknowledge
Byte 1
TX Counter
Byte 2
Length
Byte 3
Data
Max Rx Bytes
Command: The command byte allows the data in the receive and transmit buffers to be flushed.
Bit 6 – Clear Rx Buffer (Set bit to clear)
Bit 3 – Clear TX Buffer (Set bit to clear)
Rx Counter: If the Rx Handshaking attribute is enabled the Rx Acknowledge must be set to the value of
Rx Counter (0-255) in the Receive data attribute before the data field will be updated with a new serial
packet. Setting Rx Acknowledge to ‘0’ will reset the Rx Counter to ‘0’. If Rx Handshaking attribute is
disabled the Rx Counter is ignored and should be left at ‘0’.

TX Counter: If the TX Handshaking is enabled, the TX Counter must be incremented from its previous
value (0-255) in order for the message in the data field to be transmitted. Setting TX Counter to ‘0’ will
reset the value of TX Acknowledge. If TX Handshaking is disabled, the value of TX Counter is ignored
and the message in the Data field is transmitted each time it is written.

ToolLink Instruction Manual Rev 1.0
Time-Out:
In Time-Out mode the CDN466 measures the time delay between received serial characters. When 4
byte-times elapse between received bytes, this signals the end of the current message packet. The
CDN466 automatically calculates the 4 byte-times based on current RS232 baud rate.
Time-out = 4 bytes x 9 bits/byte ÷ data rate (bits/second)
Length:
In length mode the CDN466 is configured to receive fixed-length message packets. The length shall be
software selectable from 0 to 64 bytes.
If the length is set to 0, the CDN466 will operate in a “free running” mode. For Polled I/O messaging, all
RX buffer bytes are returned in response to a Poll Request message. If there are more RX bytes than will
fit, then the remaining bytes are sent in the next poll/explicit transaction. For free-running mode with
Change-of-State messaging, each received byte will generate a Change-of-State input message. Note
that this is not an efficient use of DeviceNet bandwidth.
Start/Stop Delimiters:
In this mode the CDN466 will search for a fixed strings to mark the stop and/or end of a serial message.
Behavior in this mode depends on the setting of the Start Delimiter String and Stop Delimiter String
attributes.
Start + Stop:
If both are used, the Start and Stop delimiters will mark the beginning and end of each message.
Characters outside of the delimiters will be igored. For example, if Start Delimiter = ‘<’ and Stop Delimiter
= ‘>’, the serial data stream “1<ABC>2<XY>3” would be returned in two separate DeviceNet messages
as “<ABC>”, and “<XY>”
Stop Delimiter:
If only the Stop Delimiter String is used, (Start Delimiter = 0,) the CDN466 will use the first character
received as the beginning of a message and the last character received as the end of message. For
example, if Stop Delimiter = “!”, the serial data stream “ABCD!EFG!HI” would be returned in two separate
DeviceNet messages as “ABCD!” and “EFG!”
Start Delimiter:
If only the Start Delimiter String is used (Stop Delimiter String = 0,) the CDN466 will use the Start
delimiter to mark the beginning of the message and will wait until it receives the number of bytes defined
by Maximum Receive Size attribute to mark the end of the message. For example, if Start Delimiter =
“&” and Maximum Receive Size = 5, the data stream “1&ABCD&EFGHIJ” would return two separate
DeviceNet messages “@ABCD” and “@EFGH”
No Delimiters:
MKS Instruments, Inc.
24
12/2006
ToolLink Instruction Manual Rev 1.0
If the Start Delimiter String and Stop Delimiter String are both set to zero, the CDN466 will operate in a
“free running” mode. For Polled I/O messaging, all RX buffer bytes are returned in response to a Poll
Request message. If there are more RX bytes than will fit, then the remaining bytes are sent in the next
poll/explicit transaction. For free-running mode with Change-of-State messaging, each received byte will
generate a Change-of-State input message. Note that this is not an efficient use of DeviceNet bandwidth.
Start Delimiter String – Attribute 11
The Start Delimiter String is a constant sequence of characters the CDN466 uses to identify that beginning of
a received serial message when the Receive Mode attribute is in the “Start/Stop Delimiter” mode. The
number of bytes in the string can be 0 (not used) to 4. The Start Delimiter set as a DeviceNet
SHORT_STRING, which includes a length byte followed by the ASCII bytes defining the string. For example,
to use the four byte string “<<<<” is the SHORT STRING
“ 4, ‘<’, ‘<’, ‘<’, ‘<’ ” or “0x04, 0x3C, 0x3C, 0x3C, 0x3C”.
Stop Delimiter String – Attribute 12
The Stop Delimiter String is a constant sequence of characters the CDN466 uses to identify that end of a
received serial message when the Receive Mode attribute is in the “Start/Stop Delimiter” mode. The number
of bytes in the string can be 0 (not used) to 4. The Stop Delimiter set as a DeviceNet SHORT_STRING,
which includes a length byte followed by the ASCII bytes defining the string. For example, to use the four
byte string “>>>>” is the SHORT STRING
“ 4, ‘>’, ‘>’, ‘>’, ‘>’ ” or “0x04, 0x3C, 0x3C, 0x3C, 0x3C”.
Rx Handshake Enable – Attribute 13
By default (Rx Handshaking disabled), the CDN466 updates the data received from the serial connection
to the DeviceNet I/O response as soon as a complete message is received. At slow DeviceNet rates,
however, there remains the possibility that more than one serial message will be received between
successive polls, resulting in loss of data.
If the Rx Handshaking Enable is set, the serial data made available in the I/O response will not be
overwritten by a new message until the user acknowledges that the data has been received. Once the
user has acknowledged the new serial data by setting the Rx Acknowledge value equal to the Rx
Counter, the I/O response will be free to update with new data.
Important: As the serial buffer may continue to receive data as the CDN466 is waiting for an
acknowledgement, the receive buffer may reach an overflow condition if new data is not acknowledged at
a sufficient enough rate.

ToolLink Instruction Manual Rev 1.0
TX Handshake Enable – Attribute 16
By default (TX Handshaking disabled,) the data in the I/O command is transmitted each time the I/O
command is written with a non-zero value for Length. If the user polls the CDN466 for newly received
serial data, the Length field must be set to zero if no data is to be transmitted.
In this case, the TX Counter performs no function and should remain at zero.
With TX Handshaking enabled, transmission of serial data is triggered from the TX Counter rather than
from the Length field. The data in the I/O response is transmitted to the serial connection when the value
of TX Counter is incremented from its previous state.
The value of TX Acknowledge will increment automatically to match the TX Counter after data from the
I/O command has finished transmitting to the serial connection. If the user waits for TX Acknowledge to
change before triggering the transmission of new data, the user should not be able to overflow the
transmit buffer.

Maximum Rx Size – Attribute 19
Value = 0 to 64 (default 12)
Maximum Rx Size sets the length of the data field in the I/O response. It should be set greater or equal to
the value of the largest message to be received from the serial connection. The produce size of the I/O
connection will be configured to 4 + Maximum TX Size (4 control bytes + Maximum Rx Size data bytes.)
Maximum TX Size – Attribute 20
Value = 0 to 64 (default 12)
Maximum TX Size sets the length of the data field in the I/O command. It should be set greater or equal
to the value of the largest message to be transmitted to the serial connection. The consume size of the
I/O connection will be configured to Maximum TX Size + 4 (4 control bytes + Maximum TX Size data
bytes).
Byte Swapping – Attribute 21
MKS Instruments, Inc.
26
12/2006
ToolLink Instruction Manual Rev 1.0
When enabled, this switches the byte positions of each byte pair in the data field poll command and poll
response. This is useful with many PLC devices that reverse the positions of each byte pair in memory,
garbling up string data.
Default byte positions: [1] [2] [3] [4] [5] [6][7]
Swapped positions:
[2] [1] [4] [3] [6] [5][7]
Note that if the last byte has an odd-numbered position, it retains the same position with “Byte Swapping”
enabled.
