INTRODUCTION
Serial Node Adapter/Serial Node Adapter + - Introduction
GENERAL DESCRIPTION
This service manual covers both the Serial Node
Adapter and Serial Node Adapter Plus. The
Plus version does everything the original Node
Adapter does and has added capabilities such as
certain I/O signals may be handled either via A-B
Remote I/O or discretely. In general, this manual
will address the two as one module and point out
the additional capabilities of the Node Adapter
Plus where applicable.
The Serial Node Adapter / Serial Node Adapter
+ Modules have three parts: 1) Allen Bradley
remote I/O (RIO) interface, 2) central processor,
and 3) serial input/output circuits.
The RIO interface contains some Allen-Bradley
(A-B) components which are licensed to Ransburg.
These are designed specically to communicate
with the proprietary protocol of the RIO serial
link. The central component of this block is an
application specic IC (ASIC) which is capable
of formatting the RIO information for use by the
central processor. The termination of the RIO
cable is made to the motherboard at the rear of
the Serial Node Adapter + Module location.
SPECIFICATIONS
Environmental / Physical
Operating Temperature: 0° to 55°C
Storage Temperature: -40°C to 75°C
Humidity: 95% Non-Condensing
Size: 100 x 160mm
Eurocard module, 25mm wide
Electrical
Power Required: 24 Vdc at 150 mA Max.
The core of the central processor is an 8032
microprocessor which communicates with the
Allen-Bradley ASIC. The 8032 provides an RS232 port from which diagnostic functions are
accomplished via internal “debugger” software.
The main software program, which includes the
“debugger” functions, is contained in an Erasable
Programmable Read-Only Memory (EPROM).
The serial I/O circuits are the interface to the other
Eurocard modules in the control rack or racks.
The Serial Node Adapter + uses two-wire serial
(CANBus) bus communication for this, and all
associated modules are equipped to receive and
send information on this bus.

Serial Node Adapter/Serial Node Adapter + - Introduction
Ransburg
MODES OF OPERATION
The Serial Node Adapter/Serial Node Adapter +
has three modes of operation, determined by what
modules need to be operated. The three modes
are: 1) MicroPak, 2) NPB (1 MicroPak, 1 Serial
Atomizer), and 3) Flex mode.
MicroPak Mode
MicroPak mode is for communication with the
MicroPak only, up to four units. This mode is
selected by setting SerNA dipswitch SW2-1 to
OFF. SW2, positions 5, 6, 7, and 8 must be set
to OFF. PLC data mapping information is shown
in Table 1 of the PLC I/O section.
NPB Mode
Node Per Bell mode communicates with one
MicroPak and one Serial Atomizer module and
is selected by setting SerNA dipswitch SW2-1 to
ON. SW2, positions 5, 6, 7, and 8 must be set to
OFF. PLC data mapping information is shown in
Table 2 of the PLC I/O section.
Flex Mode
Beginning with Serial Node Adapter/Serial Node
Adapter + version 2.02 software, this module has
the capability of communicating with one MicroPak
and any combination of Serial Atomizer (SerAT),
and Serial Digital (SerDG) modules, up to a total
of 12 modules. Note: Serial Atomizer must
have version 3.0 or higher Eprom (77118-05)
and it's SW2-4 in ON position. Space is also
reserved for Serial Analog (SerAN) modules, presently under development. This is the FLEX mode
of operation. The new version 2.02 software is
completely compatible with the old MicroPak and
Node Per Bell modes as long as the Serial Node
Adapter/ Serial Node Adapter + dipswitch SW2
is set correctly. For these older modes, SW2,
position 5, 6, 7, and 8 must be set OFF, as is currently done on Serial Node Adapter modules with
software earlier than 2.02. With these settings,
the Serial Node Adapter/Serial Node Adapter +
looks the same to the PLC and other modules as
the older versions.
determine what module is in what location. It will
then read a group of three conguration words,
which are programmed into Block Transfer Writes
from the PLC. (The instructions for making up
these conguration words are given in Appendix
1). While making this comparison, the module will
ash its "CPU" indicator. If these two congurations are the same, the Serial Node Adapter/Serial
Node Adapter + will begin communication with the
local modules, and the "CPU" indicator will stay
on solid. This method of redundant conguration
checking will prevent data from being sent to the
wrong module in case of a faulty module or one
having been removed. (PLC data mapping information is shown in Table 3 of the PLC I/O Section.)
Flex Mode Settings
The setting of the four dipswitches, SW2, 5-8 is
critical to proper operation. (See Figure 6 entitled
"SW1, SW2, and SW3 Switches". ) In order to enable FLEX mode, SW2-1 must be ON. If SW2 - 1
is ON, the positions 5-8 mean:
Position 5:
OFF means the mode is determined by SW2-1,
either MicroPak only or NPB (one MicroPak and
one Serial Atomizer). In this mode the Serial
Node Adapter version 2.02 is backward compat-
ible with existing applications.
ON (with position 1 ON) means the new FLEX
mode. This means the PLC programmer must
include the conguration information in the rst
three words of BTW.
Position 6 and 7:
These are used, as shown in Figure 1, to set the
logical rack size of the node adapter as it appears
to the PLC. The number of SerDG modules on
the bus determines the size.
Again, the Serial Node Adapter could do this
function automatically, but a faulty module or
modules removed could create an erroneous
reading.
In the FLEX mode, on power up, before sending
data to modules, the Serial Node Adapter/Serial
Node Adapter + will read the local serial bus and

CONNECTIONS AND
CONFIGURATIONS
Input Power
Required input power is regulated 24 Vdc which
is supplied by the motherboard of the rack which
contains the Serial Node Adapter. An on-board
dc-dc converter makes 5 Vdc for the module's logic
level circuits. The Serial Node Adapter + may be
installed in any one of three motherboards. The
power connections for each are shown in Figure 2.

The RIO cable may be "daisy-chained" from
one node to another per Allen-Bradley installa-
tion specications. Where a termination resistor
is specied, usually the last termination point in
a chain, install the appropriate resistor directly
across ""BLU" and "CLR" on the RIO connector.
NOTE

Serial Bus Connection To Other
Motherboards
The Serial Node Adapter/Serial Node Adapter +
communicates to other modules in the rack via the
local Serial Bus. If more than one motherboard
is communicating with the Serial Node Adapter/
Serial Node Adapter +, the Serial Bus must be
jumpered to motherboards not having a Serial
Node Adapter. This is done by a short section
of shielded twisted pair cable between connectors labeled “Serial” or “CAN”, and being sure to
observe the (+) to (+) convention.
A bus termination resistor (120 ohms, 1/2w) must
be connected across the (+) and (-) terminals of
the nal cable termination.
Serial Node Adapter/Serial

or by discrete wiring to the module's terminal
strip on the rear.
Serial Node Adapter/Serial Node Adapter + - Operation
COMMUNICATION DISCRETE WIRING
1. Serial Atomizer (SerAT) - must be paired with
Discrete I/O module (one DIO per SerAT). Connections are made via the Discrete I/O cable.
2. Serial Digital (SerDG), Cascading Digital
(CCDG) - will accept 24 Vdc signals to 8 pin
terminal strips on rear of motherboard, behind
each slot. Module must be set via dipswitch for
this I/O conguration. The I/O for both Serial and
Cascading Digital is identical.
3. Serial Analog (SerAN) - will accept 0-10 Vdc or
4-20 mA signals to 8 pin terminal strips on rear of
motherboard, behind each slot. Module must be
set via dipswitch for this I/O conguration.
COMMUNICATION REMOTE I/O
The Allen-Bradley RIO via the Serial Node Adapter
can talk to any combination of up to 12 SerAT,
SerDG, CCDG, and SerAN modules via its local
CANBus. This requires Serial Node Adapter Eprom Part #77128-04 (Version 2.02 or higher).
The local CANBus can consist of up to 4, 1/4 rack
motherboards connected together. Each motherboard has an addressing switch, which must be
set to from 0 to 3, so that each slot has a unique
bus address. The PLC data mapping for the FLEX
mode is shown in the following gures.

Conguration Word Construction
Ransburg
The above shows a group of any four of the
78145, 147, or 149 motherboards. The rotary
address switch sets an address number 0, 1, 2,
or 3 for that motherboard. Each motherboard
communicating with a given Serial Node Adapter
must have a different address number. This address number is completely independent of the
physical location of the motherboard. Each slot
in these motherboards has a number assigned
to it which is determined by which slot and which
mother-board.
The conguration words entered in the BTW's
dene what modules are located in each motherboard. Word 0 denes what modules are located
in the motherboard with address 0, word 1 denes
motherboard 1, etc. The modules are assigned an
ID number that is used to identify it and its position
in the motherboard. These ID's are:

Serial Node Adapter/Serial Node Adapter + - Operation
If the address 0 motherboard is a 78145-00, having a Serial Node Adapter in the leftmost slot,
the procedure is the same. There is simply no
contribution to a conguration word from this slot
(Word 0, bits 12-15 are zero).
If any of the slots are empty, simply enter zero
for that slot.
With MicroPak
When a MicroPak is used, there is no change to
the conguration system. There is no conguration word used for the MicroPak, but MicroPak
switch SW7 must be set at the default, address
1 (positions 1, 2, and 3 ON, position 4 OFF). In
the following example, a MicroPak motherboard
has been added to this combination.
Ransburg
The conguration words are identical to that above.
Note that at least one of the motherboards in this
example must be located in another physical rack.
The above examples show a maximum number
of modules communicating with one Serial Node
Adapter. A more practical system (single bell)
might be:
