Mounting & Removal
When attaching the module to the
T-type DIN rail, angle the top of the
unit towards the rail and locate the
top groove of the adapter over the
upper lip of the rail. Firmly push the
unit towards the rail until it snaps into
place. To remove, first separate the
input terminal block(s) from the
bottom side of the module to create a
clearance to the DIN mounting area.
Next, while holding the module in
place from above, insert a
screwdriver into the lower arm of the
DIN rail connector and use it as a
lever to force the connector down
until the unit disengages from the rail
(do not twist the screwdriver to avoid
damaging plastic).

may not include automatic crossover. As such, you must use a crossover
cable like that shown below when connecting this device directly to a PC.
A crossover cable simply
connects the differential
transmit pair on each end, to
the receive pair on the
opposite end.

TIP: You can significantly enhance the EMI/RFI performance of your
network connections by using Category 5E STP cable (Shielded Twisted
Pair) with shielded RJ45 plug connectors. This will also help to protect your
installation from damage due to ESD (Electro-Static Discharge). The use of
shielded cable is strongly recommended for installations in harsh industrial
environments and/or in the presence of strong electrical fields.
You can use an Ethernet switch or switching hub to build a network of
Ethernet modules, similar to that shown below. This drawing shows how to
network-connect Acromag Series 9xxEN modules to a 5-port Ethernet
switch (Acromag Model 900EN-S005). Note that the 900EN-S005 switch
includes automatic MDI/MDI-X crossover and a straight-through or
crossover cable(s) may be used to connect to the modules and the PC.

IMPORTANT: IF THE HOST PC CONNECTS DIRECTLY TO THE MODULE,
YOU MUST USE A CROSS-CONNECT CABLE (MDI-X), AS BOTH THE PC

Network Configuration
Note that Acromag series
9xxEN Ethernet I/O modules
may take from 3 to 30 seconds
to boot upon power-up,
depending on your network
configuration and whether a
DHCP server is present.
Use the scroll bar on the right to scroll down the page as shown below:
An IP Address is a unique identification number for any host (this module)
on any TCP/IP network (including the internet). The IP address is made up
of four octets (8 bits), each octet having a value between 0-255 (00H-FFH).
It is expressed here in decimal form, with a period placed between octets.

Network Configuration
A Static IP Address is as the name implies—static, and represents a unique
fixed IP Address that is generally assigned by your service provider or
system administrator. The default mode static IP address assigned to this
module is 128.1.1.100 (refer to product side label).
NOTE: In order to network your PC with an Acromag module, you may have
to consult with your network administrator and either temporarily change
your TCP/IP configuration (see TCP/IP Properties of Network Configuration
in Windows), or create a separate private network using a second network
adapter installed in your PC (recommended). The necessary steps will vary
with your operating system. Refer to Acromag Application Note 8500-734 to
help accomplish this (located on the CDROM shipped with your module or
via download from our web site at www.acromag.com).
This module can be placed
into a default communication
mode via the DFT toggle
switch at the front of the
module.
Default Mode uses a static IP
address of “128.1.1.100”, a
default subnet mask of
“255.255.255.0”, a default
username “User”, and a
default password
“password00”.
The Number of Sockets refers to the number (1-10) of Modbus TCP/IP
access points to allow for this host. The default allows up to 10 sockets, but
you can restrict access by reducing this number. Internally, the module uses
port number 502 which is reserved for Modbus.
The DNS Server refers to the IP address of the Domain Name Server used
on this network. A DNS server relates symbolic names to actual IP
addresses, while the DHCP server is responsible for dynamically passing out
IP addresses.
A Subnet Mask is used to subdivide the host portion of the IP address into
two or more subnets. The subnet mask will flag the bits of the IP address
that belong to the network address, and the remaining bits correspond to the
host portion of the address. The unique subnet to which an IP address
refers to is recovered by performing a bitwise AND operation between the IP
address and the mask itself, with the result being the sub-network address.
Gateway refers to the IP Address of the gateway, if your local area network
happens to be isolated by a gateway. If a gateway is not present, then this
field should contain an unused address within the host subnet address
range. Typically, it is assigned the first host address in the subnet.
The Host Name is the name to be assigned to this host if its address
happens to be assigned dynamically using DHCP.
The Active IP Address refers to the current IP Address being used by this
host, as opposed to any new assignments being made via this page.
The MAC Address refers to the Media Access Control Address that
uniquely identifies the hardware of this device. This is a unique fixed
address assigned to this module at the factory. In IEEE 802 networks, the
Data Link Control (DLC) layer of the OSI Reference Model is divided into two
sublayers: the Logical Link Control (LLC) layer, and the Media Access
Control (MAC) layer. The MAC layer interfaces directly with the network
media (each different type of network media requires a different MAC layer).
By default, the module is setup to use Static IP Addressing and a Static IP
Address of 128.1.1.100. You can optionally choose to have the IP address
assigned dynamically via DHCP/BOOTP or DHCP/BOOTP w/Fallbacks.
This will also require that you specify a valid Host Name. Note that
DHCP/BOOTP w/Fallback will revert to the static IP address if your DHCP or
BOOTP server cannot be found at the address specified.

In general, BOOTP (Bootstrap Protocol) refers to an internet protocol that
enables a diskless workstation to discover its own IP address, the address of
a BOOTP server on the network, and a file to be loaded into memory to boot
the machine. This enables the workstation or device server to boot without
requiring a hard or floppy disk drive. BOOTP works similar to DHCP, but is
usually found in older systems. This protocol is defined by RFC 951.

Network Configuration
DHCP (Dynamic Host Configuration Protocol) refers to a protocol for
assigning dynamic IP addresses to devices on a network. With dynamic
addressing, a device can have a different IP address every time it connects
to the network. In some systems, it can even change while it is still
connected. DHCP also supports a combination of static and dynamic IP
addresses. DHCP/BOOTP with fallback will revert to static IP addressing if
the DHCP or BOOTP server cannot be found.
The unit includes a default address toggle switch to cause the module to
assume a preset default factory address. This switch is at the front of the
module and is used to toggle the module into, or out of Default Mode. If you
use the toggle switch at the front of the module to place the module in
default mode, then “Default Communications Mode” will be indicated at the
bottom of this screen.
Click the Submit button to complete any changes made on this page.
The Default Communication
Mode uses a static IP address
of “128.1.1.100”, a default
subnet mask of
“255.255.255.0”, a default
username of “User”, and a
default password of
“password00”.
Click the Wink On/Off button to toggle the module in/out of “wink” ID mode.
In this mode, the module’s green RUN LED will blink to confirm identification.
Refer to the Technical Reference section of this manual to learn more about
IP Addressing terms and concepts.
After completing your username and password assignment, plus your
network configuration parameters, you can use the Test Page to operate
your module. The Test Page will allow you to read inputs and change input
ranges on this model.

Use the scroll bar on the right to scroll down the page as shown below:
Test Page
TIP: Viewing a module’s web
page is treated similar to
viewing a web page on the
internet. The first time you
open a page, its image is
stored as a temporary internet
file in PC memory. However,
each subsequent attempt to
view that page will need to
automatically update that
image, especially when
making configuration changes.
With Internet Explorer, click
the “Internet Options” of the
“Tools” menu, select the
“General” tab, locate the
“Temporary Internet Files”
information and click on the
“Settings” button. Then select
“Automatically” under “Check

return to the “General” screen,
and click [OK] again to save
your settings.
Note that the 12 channels of this module are divided into 3 groups (ports) of
4 channels each. Each port represents one pluggable I/O terminal block (6
screws). Port Number 0 refers to channels 0-3, port number 1 refers to
channels 4-7, and port number 3 to channels 8-11. Input signals for each
channel are indicated to 3 decimal places as shown.
IMPORTANT: The input level indicated only reflects the level of the inputs
at the moment this screen is invoked and this does not continuously update.
You can click your browser’s refresh button to get a new input update.
You can also use the Port Configuration Control of this page to change the
input range for the channels on a port-by-port basis. For the 964EN shown,
you may select from bipolar voltage ranges ±1V, ±5V, or ±10V. For the
963EN, you could choose 0-20mA, 4-20mA, 0-11.17mA, or 0-1mA. Note
that the 0-11.17mA range is intended to be used with an optional AC current
sensor (Acromag Model 5020-350) which will output 0-11.17mADC for
various 50-60Hz AC current ranges.
Note that your range selection will apply to all channels of the entire port
(group of four channels). Click on “submit” to execute your range change.

IMPORTANT: For best results, be sure to use a precision signal source
capable of reproducing the nominal endpoint signals at least as accurate as
the module itself (better than ±0.1% of span). Always allow the module to
warm up a few minutes prior to calibration.
You can choose to use the
web browser calibration page
to accomplish calibration
(easiest), or via direct register
access as described below.
Method 1 – Calibration Using The Built-In Browser Interface:
1. Make sure that the range that needs calibrating is currently selected.
2. Bring up the browser interface and select the calibration page.
3. Apply either the zero or span input signal to the channel to be calibrated.
Calibrate the zero endpoint signal first, before the span endpoint signal.
4. Wait about 10 seconds for the input to settle and be read.
5. Click on the channel number and select either zero or span calibration.
6. Click the “Calibrate” button. The page will first refresh & then calibration
may continue. Repeat this process for the other endpoint (span).
7. Repeat steps 2-5 for the other input channels to be calibrated.
Method 2 - Calibration Via The Modbus TCP/IP Interface:
1. Write to the appropriate Port Input Range Register to select the input
range to be calibrated for your channel of interest.
2. Write 24106 (5E2AH) into the Calibration Access Register to remove
write protection from the calibration registers.
3. Apply the zero calibration signal (Cal Lo, see table) to the input to be
calibrated and allow the input to settle about 10 seconds.
4. Write a 16-bit value to the Zero Calibration Register with a set bit in the
bit position that corresponds to the channel number to be calibrated (one
channel at a time). If you were calibrating the zero of channel 5, you
would write 0x0010 to the Zero Calibration Register. The module will
replace calibration coefficients immediately, no reset needed.
5. Apply the full-scale calibration signal (Cal Hi, see table) to the input to be
calibrated and allow the input to settle about 10 seconds.
6. Write a 16-bit value to the Span Calibration Register with a set bit in the
bit position that corresponds to the channel number of the channel to be
calibrated (one channel at a time). For example, if you wanted to
calibrate the span of channel 0, write 0x0001 to the “Span Cal Register”.
7. Write to the Port Input Range Register to select the next range to be
calibrated for this channel. Repeat steps 3-6 for the next range as
required.
8. Repeat steps 3-7 for the other channels as required.
9. When finished calibrating, write 0x0000 to the Calibration Access
Register (Holding register 21) to replace write protection to the
calibration registers and prevent miscalibration.

TROUBLESHOOTING
Trouble Browsing Your
Module?
Please refer Acromag Application Note 8500-734 for help in setting up
network communication with your module (located on the CDROM shipped
with your module or via download from our web site at www.acromag.com).
This document gives details for changing your PC’s TCP/IP configuration in
order to communicate with your module (see TCP/IP Properties of Network
Configuration in Windows).
If you have carefully followed this procedure and you still cannot browse your
module, you may have the web browser of your laptop or PC setup to use a
proxy server when browsing the web. If you are using Internet Explorer,
Refer to the “Tools” pulldown menu, select “Internet options…”, click the
“Connections” tab, then click the “LAN Settings” button. Locate the Proxy
server information and uncheck the box next to the statement “Use a proxy
server for your LAN”. Then click [OK] to return to the “Connections” screen,
and click [OK] again to save your settings.
You should now be able to use Internet Explorer to browse the module as
required. However, to later restore your PC’s connection to your company
network, you may have to re-enable the use of a proxy server for your LAN.
Getting Out Of Trouble
There is no built-in error detection to prevent you from writing invalid values
to a configuration register. As such, if you inadvertently write an invalid value
to an internal register, you could cause the module to become inoperable
under certain conditions. If this happens, in order to regain control of the
module, the module can either be re-downloaded at the factory, or you can
try restoring the module to its initial configuration by following this procedure:
So, your module’s “gone wild”,
follow this procedure to restore
it to its initial configuration and
regain control.
Procedure For Restoring any 9xxEN Module to its Initial Configuration

While module power is OFF, press and hold the front-panel toggle
switch in the default (DFT left) position.
While continuing to hold the toggle switch in the default position, apply
power to the module.
After a few seconds, the Status LED will begin to blink quickly and you
can release the default switch at this point. The module will continue to
boot itself as it normally does. That is, the green RUN LED will blink for
1-10 seconds as the unit acquires its address, then remain ON for
normal operation.
If the STATUS LED fails to blink rapidly after a few seconds and the
RUN LED just blinks for a few moments as it normally does, then
reinitializing the module has failed and you should try it again. This
time, make sure that the DFT switch is completely depressed and held
while powering the unit. Also make sure that you are pressing the DFT
toggle in the DFT direction (left), rather than the RST direction (right).

BusWorks® 963/964EN Module User’s Manual
Ethernet Analog Input
__________________________________________________________________
These input modules will interface with up to twelve analog input channels of
DC current or DC voltage according to the model number, and provide an
isolated 10/100 Ethernet interface for configuration, monitoring, and control
of the input module. The 963EN will also condition AC current input signals
when used with an optional AC current sensor (Acromag Model 5020-350).
Input channels are arranged in three groups (ports) of four inputs, which are
driven to separate channels of the A/D converter. Because each port feeds
a different A/D channel, each channel of the port must have the same input
range. However, different ports may use different input ranges. Current
inputs sink into a precision 50Ω resistor (963EN). Voltage inputs feed
precision 10:1 resistive dividers (964EN). A multiplexer is used to connect
the voltage from each channel of a port to a channel of the A/D converter
(one A/D channel per port). The A/D converter then applies gain to the
signal, converts the analog signal to digital, and then digitally filters the
signal. The digitized signal is then transmitted serially to the microcontroller.
The microcontroller completes the transfer function according to the input
type and range per its embedded program. Configuration and calibration
parameters are stored in non-volatile memory integrated within the
microcontroller. The I/O terminals and the Ethernet port terminals also
include transient suppression. A dedicated Ethernet controller handles
Ethernet communication. A wide input switching regulator (isolated flyback)
provides isolated power to the I/O circuits and the Ethernet controller. Refer
to the simplified schematic shown below to help gain a better understanding
of the circuit.

TCP/IP refers to Transmission Control Protocol and Internet Protocol.
TCP/IP allows blocks of binary data to be exchanged between computers.
TCP/IP is everywhere and is the foundation for the World Wide Web. The
primary function of TCP is to ensure that all packets of data are received
correctly. IP makes sure that messages are correctly addressed and routed.
Note that the TCP/IP combination does not define what the data means or
how the data is to be interpreted, it is merely a transport protocol.
19
ABOUT MODBUS
TCP/IP
Modbus is an application protocol. It defines rules for organizing and
interpreting data and is essentially a messaging structure that is independent
of the underlying physical layer. It is freely available and accessible to
anyone, easy to understand, and widely supported by many manufacturers.
Modbus TCP/IP uses TCP/IP and Ethernet to carry the data of the Modbus
message structure between devices. That is, Modbus TCP/IP combines a
physical network (Ethernet), with a networking standard (TCP/IP), and a
standard method of representing data (Modbus). In effect, a Modbus
TCP/IP message is simply a Modbus communication encapsulated in an
Ethernet TCP/IP wrapper.
In practice, Modbus TCP embeds a Modbus data frame into a TCP frame,
sans the Modbus checksum, as shown in the following diagram. The
Modbus checksum is not used, as the standard ethernet TCP/IP link layer
checksum methods are instead used to guaranty data integrity.

MODBUS FRAME
Note that the Modbus address field is referred to as the Unit Identifier in
Modbus TCP. In a typical slave application, the Unit ID is ignored and just
echoed back in the response.
The operation of the 963/964EN industrial Ethernet modules is very similar
to Acromag’s 913/914MB ModBus modules. The operation over Ethernet is
essentially transparent to the Modbus register/command structure. If you
are already familiar with Modbus or with Acromag Series 900MB modules,
then you are already familiar with the operation of the 963/964EN modules.
A host is any device on any network. On TCP/IP networks, each host has
one or more unique IP addresses. This module connected to an ethernet
network is a host.
IP Addressing
An IP Address is a unique identification number for any host (this module) on
any TCP/IP network (including the internet). The IP address is made up of
four octets (8 bits), each octet having a value between 0-255 (00H-FFH).
The IP address is comprised of two parts: the network address (first part)
and the host address (last part). The number of octets of the four total that
belong to the network address depend on the Class definition (see below).

__________________________________________________________________
IP Addressing
A Static IP Address is as the name implies—static. That is, it is a unique IP
Address that is assigned by a service provider and never changes.
A Dynamic IP Address is an address that is temporarily assigned to a user
by a service provider each time a user connects.
A Subnet is a contiguous string of IP addresses. The first IP address in a
subnet is used to identify the subnet, while the last IP address in a subnet is
always used as a broadcast address. Anything sent to the last IP address of
a subnet is sent to every host on the subnet.
Subnets are further broken down into three size classes based on the 4
octets that make up the IP address. A Class A subnet is any subnet that
shares the first octet of the IP address. The remaining 3 octets of a Class A
24
subnet will define up to 16,777,214 possible IP addresses (2 – 2). A Class
16
B subnet shares the first two octets of an IP address (providing 2 – 2, or
65534 possible IP addresses). Class C subnets share the first 3 octets of an
IP address, giving 254 possible IP addresses. Recall that the first and last
IP addresses are always used as a network number and broadcast address
respectively, and this is why we subtract 2 from the total possible unique
addresses that are defined via the remaining octet(s).
TIP: the first node (0), node
10, and the last node (255 for
our example) are typically
reserved for servers and may
yield poor results if used.
For our example, the default IP address of this module is 128.1.1.100. If we
assume that this is a Class C network address (based on the default Class
C subnet mask of 255.255.255.0), then the first three numbers represent this
Class C network at address 128.1.1.0, the last number identifies a unique
host/node address on this network (node 100 at address 128.1.1.100).
A Subnet Mask is used to determine which subnet an IP address belongs to.
The use of a subnet mask allows the network administrator to further divide
the host part of this address into two or more subnets. The subnet mask
flags the network address, plus the bits of the host portion that are used for
identifying the subnetwork. By convention, the bits of the mask for the
subnetwork address are all set to 1’s (it would also work if the bits were set
exactly as in the network address). It’s called a mask because it can be
used to identify the unique subnet to which an IP address belongs to by
performing a bitwise AND operation between the mask itself, and the IP
address, with the result being the subnetwork address.
For our Example, if we wish to further divide this network into 14 subnets,
then the first 4 bits of the host address will be required to identify the
subnetwork (0110), then we would use “11111111.11111111.11111111.
11110000” as our subnet mask. This would effectively subdivide our Class
C network into 14 subnetworks of up to 14 possible nodes each.
With respect to the default settings of this module:
Subnet Mask 255.255.255.0 (11111111.11111111.11111111.00000000)
IP Address: 128.1.1.100
(10000000.00000001.00000001.01100100)
Subnet Address: 128.1.1.0 (1000000.00000001.00000001.00000000)
The subnetwork address of 128.1.1.0 has 254 possible unique node
addresses (we are using node 100 of 254 possible). Node 0, 10, and 255
addresses are typically reserved for servers and may yield poor results if
used.

DHCP refers to Dynamic Host Configuration Protocol and is a method used
to dynamically assign temporary numeric IP addresses as required. A
DHCP server maintains a pool of shared IP addresses which are recycled.
When a DHCP device wants to use a TCP/IP application, it must request an
IP address from the DHCP server. The DHCP server will check the shared
supply, and if all addresses are in use, the server will send a busy signal to
the client which tells it to try again later. Static addresses will ensure a
connection every time, but dynamic addresses do not.
Dynamic Host
Configuration Protocol
(DHCP)
DNS refers to the Domain Name System or Domain Name Server and refers
to the system used to associate an alphanumeric character string with a
numeric IP address. The DNS is actually a distributed database of domain
names and corresponding IP addresses. These servers contain information
on some segment of the domain name space and make this information
available to clients called resolvers. For example, the DNS allows us to use
“Acromag.com” as an IP address rather than a complicated number string.
Domain Name System
(DNS)
Modbus registers are organized into reference types identified by the leading
number of the reference address:
MODBUS
REGISTERS
Reference
0xxxx
Description
Read/Write Discrete Outputs or Coils. A 0x reference
address is used to drive output data to a digital output
channel.
1xxxx
Read Discrete Inputs. The ON/OFF status of a 1x
reference address is controlled by the corresponding
digital input channel.
3xxxx
Read Input Registers. A 3x reference register contains a
16-bit number received from an external source—e.g. an
analog signal.
4xxxx
Read/Write Output or Holding Registers. A 4x register is
used to store 16-bits of numerical data (binary or decimal),
or to send the data from the CPU to an output channel.
Note: The ON/OFF state of discrete inputs and outputs is represented by a
1 or 0 value assigned to an individual bit in a 16-bit data word. This is
sixteen 0x or 1x references per data word. With respect to mapping,
the LSB of the word maps to the lowest numbered channel of a group
and channel numbers increase sequentially as you move towards the
MSB. Unused bit positions are set to zero.
The “x” following the leading
character represents a fourdigit address location in user
data memory.
The leading character is
generally implied by the
function code and omitted from
the address specifier for a
given function. The leading
character also identifies the
I/O data type.
All I/O values are accessed via the 16-bit Input or Holding Registers given in
the Register Map. Input registers contain read-only information. For
example, the current input value read from a channel, or the states of a
group of digital inputs. Holding registers contain read/write information that
may be configuration data or output data. For example, the high limit value
of an alarm operating at an input, or an output value for an output channel.
Each module has a default factory configuration as noted in the
SPECIFICATIONS section. Your application will likely differ from the default
configuration and the module will need to be reconfigured. You may
reconfigure this module by issuing the appropriate Modbus functions to
Register Map registers, as required by your application. You may also use a
standard web browser to access the built-in web pages of the module to
perform basic operations.

Register Functions
Below is a subset of standard Modbus functions that are supported by this
module along with the reference register addresses that the function
operates on. Use these functions to access these registers as outlined in
the Register Map for sending and retrieving data.
IMPORTANT: When using
your own software to
manipulate the module, please
note that the maximum query
through the Modbus TCP
interface is only 50 registers,
due to the maximum buffer
size limitations of the TCP/IP
stack. As such, you can only
request data from 50 registers
at one time for commands that
access multiple registers. For
example, the Read Holding
Registers command may only
retrieve the contents of
registers 40001 to 40051 in
one read.
The following Modbus functions operate on register map registers to
monitor, configure, and control module I/O:

02 (02H)
03 (03H)

written with an invalid value, exception code 03 (Illegal Data Value) will be
returned in the response message. You may refer to the Modbus

Register Mirroring
For your convenience, 9xxEN Ethernet modules mirror the contents and
operation of registers 0xxxx, 1xxxx, & 3xxxx (as applicable) into holding
register space (4xxxx) for systems and controllers that cannot directly
access registers 0xxxx, 1xxxx, & 3xxxx.
All Modbus registers of this model can now be written to, or read from, using
either the standard methods described in the Modbus specification, or
through mapping (mirroring) to the Holding Registers. The registers are
mapped as follows and specifics follow the mapping:

0xxxx Coil Registers are mapped to 42xxx Holding Registers
1xxxx Input Status Registers are mapped to 41xxx Holding Registers
3xxxx Input Registers are mapped to 43xxx Holding Registers
23
Register Mirroring
For 3xxxx Input Registers, the format of the registers are identical and you
only need to offset your address by 43000. For example: if you want to read
Input Register 1 through the Holding Registers, you would use the “Read
Holding Registers” function with an address of 43001.
For the 1xxxx Input Status Registers (where supported), the return data is
reformatted to match the Holding Register format. For example: if you
request the Input Status for 12 digital inputs, instead of getting 2 bytes
returned with the first 12 bits representing the 12 digital inputs, you will get
12 separate words, each set to either 0000H (OFF), or FFFFH (ON).
For the 0xxxx Coil Registers (where supported), reads are handled in the
same way as the 1xxxx Input Status Registers. You can also write to the coil
registers by using the “Preset Single Register” function with an address
offset of 42000. Setting the data to 0000H will turn the coil OFF, while setting
the data to FF00H will turn the coil ON. Writing to multiple coils is not
supported via register mirroring, you must use the “Write Multiple Coils”
function for that.
Note that with respect to Acromag 9xxMB Modbus RTU modules, only 3xxxx
Input Registers are mirrored into 4xxxx space, not Coil or Input Status
registers as noted here for 9xxEN models.
I/O values for Series 900EN modules are represented by the following
simple data types for temperature, percentage, and discrete on/off.
Data Types
Summary Of Data Types Used By 900MB/900EN Modules
Data Types
Description
Count Value A 16-bit signed integer in range of -32768 to +32767, or
unsigned integer in range of 0 to 65535, representing an
A/D or DAC count, time value, or frequency.
A
16-bit signed integer value in range of -32768 to
Percentage
(This Model) +32767. ±20000 is used to represent ±100%, yielding a
resolution of 0.005%/lsb. For example, -100%, 0% and
+100% are represented by decimal values –20000, 0,
and 20000, respectively. The full range is –163.84%
(-32768 decimal) to +163.835% (+32767 decimal).
Temperature A 16-bit signed integer value with resolution of 0.1°C/lsb.
For example, a value of 12059 is equivalent to 1205.9°C,
a value of –187 equals –18.7°C. The maximum possible
temperature range is –3276.8°C to +3276.7°C.
Discrete
A discrete value is generally indicated by a single bit of a
16-bit word. The bit number/position typically
corresponds to the discrete channel number for this
model. Unless otherwise defined for outputs, a 1 bit
means the corresponding output is closed or ON, a 0 bit
means the output is open or OFF. For inputs, a value of
1 means the input is ON (Active low near 0V), while a
value of 0 specifies the input is OFF or in its high state
(usually >> 0V).

Notes (Memory Map):
1. Input values are 16-bit signed integer values representing percent with a
resolution of 0.005%/lsb. ±20000 is used to represent ±100%. The full
range is –163.84% (-32768 decimal) to +163.835% (+32767 decimal).
For example, -100%, 0% and +100% are represented by decimal values
–20000, 0, and +20000, respectively. Bipolar voltage ranges (964EN)
use ±100% (span of –20000 to +20000), current ranges (963EN) use 0100% (span of 0 to 20000).
2. The 964EN A/D Count value is calculated via the expression: count =
(32768*Vin*Gain/Vref)+32768, where Vref=1.235V. Gain is 1 (±10V
range), 2 (±5V), and 8 (±1.0V).
The 963EN A/D Count value is calculated via the expression: count =
(32768*Iin*49.9Ω*Gain/Vref)+32768, where Vref=1.235V. Gain is 1 (020mA & 4-20mA range),
2 (0-11.17mA range), or 16 (0-1mA range).
3. WARNING: Access to calibration registers 40022 through 40129 is not
normally required and unintentional writes to these registers should be
avoided to prevent module miscalibration.

BusWorks® 963/964EN Module User’s Manual
Ethernet Analog Input
__________________________________________________________________
SPECIFICATIONS
These DIN-rail mount, industrial ethernet, analog input modules include
twelve analog input channels for DC current (963EN), or DC voltage
(964EN), and provide an isolated 10/100BaseT Ethernet port for monitoring
and control. Units are DC-powered and include reverse polarity protection.
Analog inputs (as a group), network, and power are isolated from each
other. Input channels share common. Non-volatile reprogrammable
memory in the module stores configuration and calibration information.
Model Numbers
The BusWorks model prefix “900” denotes the Series 900 network I/O
family. The “EN” suffix denotes EtherNet. Select 963EN for current input,
and 964EN for voltage input. The four digit suffix of this model number
represents the following options, respectively: “4” = Ethernet; “0” = Default;
“12” = 12 Channels.
963EN-4012 (Current)
964EN-4012 (Voltage)
Analog Inputs
Twelve analog input channels with a common (RTN) connection for DC
current or DC voltage applications only. AC current inputs can be
accommodated when the 963EN is used with an optional AC current sensor
(Acromag Model 5020-350). Units must be wired and configured for the
intended input type and range (see Connections Section for details). The
unit can accept one of several input ranges as described below.
DC Current (963EN Only): Configurable for 0 to 20mA, 4-20mA, 011.17mA, and 0-1mA DC nominal input ranges. A precision 49.9Ω
current sink resistor converts the input current to a voltage that is
processed by the A/D converter. An optional external sensor is
required to monitor AC current signals (Acromag Model 5020-350).
This sensor generates a DC milliampere signal of 0 to 11.17mA for the
module (see Table 1 below for scaling to AC current).
Current Input Reference Test Conditions: 4 to 20mA current input;
Ambient Temperature = 25°C.
Input Overvoltage Protection: Bipolar Transient Voltage Suppressers
(TVS), 5.6V clamp level typical.
Optional AC Current Sensor (Model 5020-350, For Use With
963EN): This sensor is a toroidal instrument transformer that converts
a sinusoidal 50-60Hz AC current signal into a low level DC milliampere
signal of 0 to 11.17mA. The input AC current range is a function of the
number of turns placed through the toroid as shown in Table 1 below.
This sensor is isolated and requires no calibration or adjustment. When
used with a 963EN module, it provides redundant input isolation and
may facilitate input-to-input isolation of this twelve channel unit.

The output wires of this sensor are polarized with red as (+) plus and
black as (-) minus. Normally these output wires are attached to one
end of a user supplied cable, while the other end connects to the
963EN’s process current input terminals.

Input Burden: A function of the wire gauge resistance used for primary
turns (the current carrying wire being monitored).
AC Current Sensor to Transmitter Wiring Distance: 400 feet
maximum for 18 gauge wire. Other wire gauges can be used as long
as the resistance of both wires is less than 5Ω.
Input Overload: The AC current sensor will withstand overload
conditions as follows:
• 20 times full scale for 0.01 seconds.
• 10 times full scale for 0.1 seconds.
• 5 times full scale for 1.0 second.
33
Analog Inputs
DC Voltage (964EN Only): A 10:1 input divider is installed at the input
(using divider resistor values of 100K and 10.5K). Configurable for
bipolar DC voltage ranges of -1V to 1V, -5V to 5V, and -10V to 10V.
Input Impedance: 110.5KΩ.
Voltage Input Reference Test Conditions: -10 to 10V DC Input;
Ambient Temperature = 25°C.
Input Overvoltage Protection: Bipolar Transient Voltage Suppressers
(TVS), 18V clamp level typical.
Note: Channels of the same port (each group of 4 channels) must share the

Controls & Indicators
Communication Distance: The distance between two devices on an
Ethernet network is generally limited to 100 meters using recommended
copper cable. Distances may be extended using hubs, switches, or
fiber optic transmission. However, the total round trip delay time must
not exceed 512 bit times for collision detection to work properly.
Port Status Indicators: Green LED indicates link status (ON if autonegotiation has successfully established a connection), yellow LED
indicates activity (ethernet connection is busy/traffic is present).
Address: The module IP address can be preset by the user (static) and
loaded from internal non-volatile memory, or it can be automatically
acquired at startup via the network server using a BOOTP (Bootstrap
Protocol), or DHCP (Dynamic Host Configuration Protocol). The unit
also includes a default mode toggle switch to cause the module to
assume a “known” fixed static IP address of 128.1.1.100 for
troubleshooting purposes.
LED Indicators:
RUN (Green) - Constant ON if power is on and unit is OK. Continuous
flashing ON/OFF indicates unit is in “wink” ID mode.
ST (Yellow) – Slowly blinks ON/OFF in default mode, constant ON if one
or more inputs are over/under-range.
LINK (Green) – Indicates Ethernet link status (ON if auto-negotiation has
successfully established a connection).
ACT (Yellow) – Blinking indicates Ethernet activity (Ethernet connection
is busy/traffic is present).
Controls:
Reset/Default Address Switch: This momentary toggle switch is
located on the front panel and is used to either reset the module
(toggle right), or toggle the module into, or out of Default
Communication Mode (toggle left). In Default Mode, the module
assumes the fixed static IP address “128.1.1.100”, a default subnet
mask “255.255.255.0”, a default username of “User”, and a default
password of “password00”. This switch can also be used to restore
the module to its initial factory configuration by holding this switch in
its default position while powering up the unit (see “Getting Out Of
Trouble” in the Troubleshooting section for more information).

The minimum cable required for full operation of this device is Category 5.
The term “Category” refers to classifications of UTP (Unshielded Twisted
Pair) cables. There are 3 main categories of cable – Category 3, Category
4, and Category 5. The differences in classification is found in their electrical
performance and this is documented in the TIA/EIA 568A standard.
Category 5 cable includes four twisted wire pairs at eight twists per foot.
37
ACCESSORY
CABLES
This device is designed for use in harsh industrial environments. Acromag
recommends the use of shielded cable when wiring to this device. Select
STP (Shielded Twisted Pair) cable rather than UTP (Unshielded Twisted
Pair). The use of shielded cable will help protect the data being transmitted
from harmful EMI (Electromagnetic Interference) and RFI (Radio Frequency
Interference). It will also help to lower your radiated emissions by keeping
the cable from emitting EMI and RFI.
There are two types of cable conductors: solid cable and stranded cable.
Stranded cables are more flexible than solid cables. But since attenuation is
higher for stranded cables than solid conductor cables, these are generally
reserved for short runs and patch applications less than 6 meters.
Currently there are two types of cable shielding employed in Category 5 STP
cable: single-shielded cable and double-shielded cable. Both of these
cables have the same core and jacket as UTP cables, but also include a thin
foil outer shield that covers all four twisted-wire pairs. Some variations will
also include a drain wire that encircles the outer foil. The double-shielded
version adds an outer wire screen that wraps around the foil shield and also
functions as a drain wire. The drain wire or wire screen typically makes
contact at each end of the cable with the metal shield around special RJ45
plug connectors. The metal shield of these connectors then makes contact
with the metal shield of shielded RJ45 sockets. The socket shield may
make direct contact with earth ground, or it may be capacitively coupled to
earth ground.
In the Acromag 9xxEN modules, this shield contacts earth ground via a high
voltage capacitor and transient voltage suppressor. In addition to minimizing
radio frequency and electromagnetic interference, this arrangement also has
the added benefit of enhanced protection from damage due to ESD (ElectroStatic Discharge).
Further, Acromag recommends the use of enhanced Category 5 cable
(CAT-5e). This cable has all the characteristics of Category 5, but includes
enhancements that help to minimize crosstalk. It is rated for frequencies up
to 200MHz, double the rate of Category 5. Category 5e cable also has a
greater number of turns-per-inch in its twisted pairs, making its performance
more suitable for applications that make use of all four wire pairs for
simultaneous bidirectional data transmission (full-duplex). This cable is
defined in TIA/EIA-568A-5 (Addendum 5).

Patch Cable &
Crossover Cable
Acromag offers the following cable accessories for use with this module:
Cable Model 5035-355 – Yellow, 3 foot long, single-shielded Category 5e
STP patch cable with drain wire and an RJ45 plug at both ends. Use this
cable to connect any Acromag 9xxEN I/O module to the 900EN-S005 switch.
Cable Model 5035-360 – Green, 5 foot long, single-shielded Category 5e
STP crossover cable with drain wire and an RJ45 plug at both ends. This
cable performs the Ethernet crossover function and is used to connect a PC
directly to an Acromag Series 9xxEN I/O module.
Note that you do not need to use a crossover cable to connect your PC to
this module if the Acromag 900EN-S005 switch is used between the PC and
module, as the switch is auto-crossing. However, you must use a crossover
cable when directly connecting your PC to a Series 9xxEN I/O Module
without the use of an auto-crossing switch or hub.
You may obtain cable in other lengths and colors as required for your
application from other vendors. For example, shielded CAT-5e cable is
available from the following vendors:
•
•
