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. irt, 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 AN 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. ocate 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.
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 ED is used to indicate the meter’s status
in relationship to the bus.

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.

A ribu e Iden ifica ion Char
➀ Data Swap: (1 byte), Attribute 1, Instance 1, Class 100 (decimal). Data is
normally sent and entered as follows: Pax display value = 500000 (7A120h).
4 byte value sent would be 20 A1 07 00. Setting the data swap value to 1
would result in the data being sent as 00 07 A1 20. This attribute can only be
set to 0 or 1, all other values are ignored. The factory setting value is 0. Data
Byte is saved in EEPROM memory.
➃ DIP Switch Values: (1 byte), Attribute 6, Instance 1, Class 100 (decimal).
Returns the dip switch setting. Switch 1 = SB, 1 = on.
➂Polling Flags: (3 bytes) Attribute 3 - 5, Instance 1, Class 100 (decimal). The
DeviceNet card is continually requesting values from the PAX unit. The
polling flags determine what values are requested during each loop. Setting
the flags to “1” enables the card to poll that particular value. A “0” value
disables it. Turning polling flags off allows the card to request fewer values
and therefore decreases the internal loop time, which allows the values that
are polled to be updated more often.
If a Set Attribute is executed for any value, that value is automatically
updated to the latest value, regardless of whether the polling flag is on or off.
On power up, all values are updated regardless of Polling flag settings.
Polling flag values are saved in EEPROM memory. Factory settings is “on”
for all Polling flags.
See Meter Attribute Identification Chart for polling flags.
➄Store Flags: (3 bytes) Attribute 26 - 28, Instance 1, Class 100 (decimal). This
set of flags determines whether the attribute is stored to EEPROM when a Set
or Reset service code is executed. If the flag is 0, the value is not saved to
EEPROM memory in the PAX. If the flag is 1, the value is saved immediately
to EEPROM memory in the PAX. Factory setting is “on” for all Store Flags.
The attributes are grouped in blocks. Storing one attribute may cause others
to be stored. If an attribute is SET frequently, its store flag should be set to 0
to increase EEPROM life.
MANUAL MODE DESCRIPTION ➅
(CSR) Control Status Register [16] (PAX)
The Control Status Register is used to directly control the meter’s outputs
(setpoints and analog output), or view the state of the setpoint outputs and the
status of the temperature sensor (PAXT only). The attribute is bit mapped with
each bit position within the attribute assigned to a particular control function.
The control functions are invoked by writing to each bit position. The bit
position definitions are:
In Manual Mode, the setpoint outputs are defined by the values written to bits
b0, b1, b2, b3; and the analog output is defined by the value written to the AOR.
Internal control of these outputs is then overridden. In automatic mode, the
setpoint outputs can only be reset off.
Example:
1. Select manual mode for all outputs:
Value to write to attribute 16: 0010h
1 value – 52 msec
5 values – 230 msec1 value – 100 msec
10 values – 430 msec5 values – 500 msec

(MMR) Auto/Manual Mode Register [23] (PAXI/PAXCK/PAXDP)
This attribute sets the controlling mode for the outputs. In Auto Mode (0) the
meter controls the setpoint output. In Manual Mode (1) the outputs are defined
by the attribute SOR. When transferring from auto mode to manual mode, the
meter holds the last output value (until the attribute is changed by a write). Each
output may be independently changed to auto or manual. Select values to place
in manual mode by writing appropriate value to attribute 23. The bit position
definitions are:
Example:
1. Select manual mode for all outputs and AOR (PAXI, PAXDP):
Value to write to attribute 23: 001Fh
(SOR) Setpoint Output Register [25] (PAXI/PAXCK/PAXDP)
This attribute is used to view or change the states of the setpoint outputs.
Reading from this attribute will show the present state of all the setpoint outputs.
A “0” in the setpoint location means the output is inactive and a “1” means the
output is active.
In Automatic Mode (See MMR Description), the meter controls the setpoint
output state. In Manual Mode, writing to this attribute will change the output
state. The bit position definitions are:
Examples:
1. Turn all outputs on:
Value to write to attribute 25 - 000Fh.
2. Turn outputs 1, 3 on:
Value to write to attribute 25 - 0005h.
3. Turn all outputs off:
Value to write to attribute 25 - 0000h.
(AOR) Analog Output Register (Not PAXCK)
The Analog Output Register controls the analog output of the meter. The
manual mode must first be engaged by setting bit 4 of the CSR (PAX) or bit 0
of the MMR (PAXI). The range of values of this attribute is 0 to 4095, which
corresponds to 0 mA, 0 V and 20 mA, 10 V; respectively. If a value larger than
4095 is written to the AOR Attribute, 4095 will be loaded. The table lists
correspondence of the output signal with the attribute value.
* ue to the absolute accuracy rating
and resolution of the output card, the
actual output signal may differ 0.15% FS
from the table values. The output signal
corresponds to the range selected (20 mA
or 10 V).
Writing to this attribute while the meter is in the manual mode causes the output
signal to update immediately. While in the automatic mode, this attribute may be
written to, but the output will not update until the meter is placed in manual mode.
Examples:
1. Set output to full scale:
Value to write to attribute 15 (PAX) or attribute 24 (PAXI) - 0FFFh (4095).
2. Set output to zero scale:
Value to write to attribute 15 (PAX) or attribute 24 (PAXI) - 0000h (0).
