MODEL PAXCDC -DEVICENET™ OUTPUT OPTION CARD
DESCRIPTION
The DeviceNet Option Card (PAXCDC30) is designed for the PAX series of
meters. It fits into the Comms slot of any PAX meter and allows the meter to
communicate with a DeviceNet bus. The card supports Polling, Bit Strobe, and
Explicit Message Commands. The MAC ID and the Baud Rate are switch
adjustable via a DIP switch. A bicolor LED is used to indicate the meter’s status
in relationship to the bus.
Bulletin No. PAXCDC3-E
Drawing No. LP0424

INSTALLING AN OPTION CARD
Caution: The option and main circuit cards contain static
sensitive components. Before handling the cards, discharge
static charges from your body by touching a grounded bare
metal object. Ideally, handle the cards at a static controlled
clean workstation. Also, only handle the cards by the edges.
Dirt, oil or other contaminants that may contact the cards can
adversely affect circuit operation.
Warning: Exposed line voltage exists on the circuit boards.
Remove all power to the meter AND load circuits before
accessing the unit.
1. Remove the main assembly from the rear of the case. Squeeze the finger
holds on the rear cover, or use a small screwdriver to depress the side
latches to release it from the case. It is not necessary to separate the rear
cover from the main circuit card.
2. Locate the option card connector for the type of option card to be
installed. Hold the unit by the rear connector, not the display board, when
installing an option card.
3. Install the option card by aligning the option card connector with the slot
in the rear cover. The cards are keyed by position with different main
board connector locations. Be sure the connector is fully engaged and the
tab on the option card rests in the alignment slot on the display board.
4. Slide the assembly back into the case. Be sure the rear cover latches fully
into the case.
5. Apply the option card label to the bottom side of the meter. Do not cover
the vents on the top surface of the meter. The surface of the case must be
clean for the label to adhere properly. Apply the label to the area
designated by the large case label.
6. See manual for wiring connections and programming procedures.

NETWORK STATUS LEDs
Flashing Red LED:
This device is the only device on the network (waiting for an
acknowledgment to its duplicate MAC ID check), or an I/O connection
has timed out, or a recoverable error has occurred.
Flashing Green LED:
The device is functioning correctly and is waiting to be commissioned
by a bus master.
Solid Red LED:
The device has encountered a non-recoverable fault, such as a duplicate
MAC ID response, and has removed itself from the bus, or the device
is in a power up reset state and is attempting to come on line.
Solid Green LED:
The device is on line, functioning correctly and has been commissioned
by a bus master.
SUPPORTED CONNECTIONS
Polled Command: The Polled Command consumes 6 bytes of data, and is used
to get, set, or reset attributes. The meter attribute is determined by the value
in byte 0 of the data field. Refer to the Attribute Identification Chart for the
appropriate value. Byte 1 determines the action: 0 = get, 1 = set, 2 = reset.
The next 4 bytes are the new attribute value for the set command. For get or
reset commands, enter 4 zeros. The data response from the Polled Command
is in the format of a 4 byte hexadecimal number. For the get command (0),
the response is the attribute value. For the set command (1), the response is
an echo of the data input. For the reset command (2), all 0s are returned.
Bit Strobe Command: The Bit Strobe Command consumes eight bytes of data,
or less. This is a read only predetermined meter attribute. The data response
from the Bit Strobe Command is in the format of a 4 byte hexadecimal
number. The register that will be read using the Bit Strobe command is
determined by setting Attribute 2, Instance 1, Class 100* (decimal) with a
value that represents the desired attribute. Refer to the Attribute Identification
Chart for the appropriate value.
*Class 100 (decimal) is a vendor specific class.
EXPLICIT MESSAGE COMMAND
Get Attribute: The attribute that will be read using the Get Attribute command
is determined by setting Service Code 14, Instance 1, Class 100* (decimal),
and the attribute with a value that represents the desired meter attribute. Refer
to the Attribute Identification Chart for the appropriate value. The data
response from the Get Attribute Command is in the format of a 4 byte
hexadecimal number.
Set Attribute: The attribute that will be set using the Set Attribute command is
determined by setting Service Code 16, Instance 1, Class 100* (decimal), and
the attribute with a value that represents the desired meter attribute. Refer to the
Attribute Identification Chart for the appropriate value. The data field for the
Set Attribute Command is entered as a 4 byte hexadecimal number.
Reset Attribute: The attribute that will be reset using the Reset Attribute
command is determined by setting Service Code 5, Instance 1, Class 100*
(decimal), and the attribute with a value that represents the desired meter
attribute. Refer to the Attribute Identification Chart for the appropriate value.
*Class 100 (decimal) is a vendor specific class.
Note: Not all meter attributes respond to a Set or Reset Attribute command.
Refer to the Attribute Identification Chart for details.
However, some meter configuration is supported.
