1 Introduction
Stream with CoreSense™Diagnostics provides advanced motor protection, diagnostics as well as Modbus®
communication. Modbus communication enables reading compressor operating and alarm information from
CoreSense both locally and remotely. By monitoring and analyzing data from the Copeland™compressor, the
module can accurately detect the cause of electrical and system related issues. If an unsafe condition is detected,
the module trips the compressor. A flashing LED indicator communicates an alert code and guides the service
technician more quickly and accurately to the root cause of a problem.
The module also has a RS-485 isolated communication port, by which the modules can communicate with the
system controller or the network master. The details of the communication are provided in this document.

1.1 Intent
This document defines the CoreSense Diagnostics module standard usage of the Modbus protocol specification.
This will allow 3rd party controllers to easily communicate to the CoreSense Diagnostics device using a standard
Modbus interface.
1.2 Scope
This document only defines the Modbus options that are used in Stream with CoreSense Diagnostics. It is not
intended to replace the Modbus protocol specification. This specification defines the common usage of the Physical
layer, Data Link layer and some parts of the Application layer interface.
1.3 References
For the details of the Modbus specification, refer to
Modicon Modbus Protocol Reference Guide PI–MBUS–300 Rev. J
www.modbus.org
2 General description
Modbus uses a three-layer protocol:
Physical layer: the hardware interface;
Data Link layer: defines the reliable exchange of messages;
Application layer: defines message structures for the exchange of application specific information.
Modbus has some required features, some recommended features, and some optional features. This specification
starts with the physical layer and then works up to the application layer. The application layer defined in this
specification defines the standard Modbus memory map and data interchange.
Modbus is a protocol with a single master and multiple slave devices. The master device initiates all messages.

D7.8.6/1112-0815/E 4/18
3 Modbus type identification
Two types of Modbus are used with Stream compressors. The only possibility to identify which one is fitted in a
CoreSense module is to open the module lid, and to look at the circuit board and label.
Most of the features are the same; the main differences are explained in this chapter.
3.1 Modbus with 10 DIP-switch
Figure 1: View of the circuit board and label for 10 DIP-switch Modbus
The information given in the following chapters is based on the operation of the Modbus new version (12 DIP-
switch).
The input and holding register tables (Chapters 6.3.2 and 6.3.3) are valid for the 12 DIP-switch version but most of
the listed commands are also valid for the 10 DIP-switch model. The following input register data are specific to the
10 DIP-switch and therefore are not listed in Chapter 6.3.2.

4 Physical layer
This layer defines the hardware interface to the network.
4.1 Topology
Stream with CoreSense Diagnostics uses the “two-wire” configuration (two signal wires plus a ground). The
standard configuration will be to directly wire to the cable forming a daisy-chain.
4.1.1 Wire used
The recommended wire is shielded twisted pair (22 AWG or 0.33 mm2). The shield is also used as the circuit
ground.
Figure 3: Recommended communication wire (shielded twisted pair 22AWG or 0.33 mm2)
4.1.2 Bus bias
All master devices must provide a means to bias the network. The recommended pull-down on the
RS485 “+” output is a 511Ω resistor, but up to a 1KΩresistor is acceptable. The recommended pull-up resistor on
the RS485 “–“ output is a 511Ω resistor, but up to 1KΩis acceptable. These bias resistors can either be always
enabled or they can be enabled through jumpers. The bias is applied at one point in the network.
4.1.3 Termination
All master devices must provide a 150Ωtermination resistor. The last slave in the network must have a
150Ω resistor for termination. In this module, there is a jumper provision to enable this termination. The jumper is
located between positions 1-2 at “JP3” (see Figure 4). The last CoreSense module in the network shall be
populated with a header on this jumper. For the other CoreSense modules in the network, this jumper needs not be
populated.
4.2 Data signalling rates
4.2.1 Baud rate selection
The default communication port default settings are 19200, no parity, 8 data, 2 stop bits. The baud rate (19200 OR
9600) and parity (Even or No parity) is user-configurable through DIP-switch. The data length and stop bits are not
configurable.
4.2.2 Parity selection
Emerson Climate Technologies Modbus communication parity is user-configurable (Even or No parity).
DIP-switch Nr. 8 On Even.
DIP-switch Nr. 8 Off No parity (default setting).

D7.8.6/1112-0815/E 7/18
4.3 Labelling
The module has a “COMM PORT” with the connector pins, labelled from left to right as:
“ + GND – ”
+ = RS485 “A” circuit connection
GND = Common
–= RS485 “B” circuit connection
4.4 Connectors
A three-position screw cable connector is used for Modbus communication.
4.5 Wiring and connections
The Modbus wiring should be connected to module connector “+”, “GND”, “–“.
Figure 5: Modbus "Comm Port"
NOTE: RS485 is polarity sensitive. "+" wires must connect to other "+" terminals and "–" wires must
connect to other "–" terminals. The shield wire is connected to the centre terminal.

D7.8.6/1112-0815/E 8/18
5 Data Link layer
Modbus uses master/slave protocol where there is a single master device that initiates all messages. The Data Link
layer defines the reliable transfer of a message transferred from the master to one or more slave devices and the
reliable transfer of the response message (when the command message is sent to a single device). The
CoreSense Diagnostics module is a slave in the network and the rack controller is the master.
5.1 Node address
The DIP-switch setting combination gives the node address. Combination positions 1 to 6 will be used to define a
node address from 1 to 62. Positions 7 to 12 will be used for Baud rate, parity, network mode, discharge
temperature protection, self-test mode, and VFD enable (Variable Frequency Drive).
Figure 6: Switches 1 to 6 are used to set the module Modbus address
See Table 1 and Tables 3 to 9 for more information about setting the DIP-switches.

5.3 RTU Transmission mode
The Modbus communication in the CoreSense Diagnostics module uses RTU mode. The default character framing
is an 11-bit character as follows:
1 start bit
8 data bits
2 stop bits (or if “Even parity” is selected 1 stop bit and 1 parity bit)
A standard 2-byte CRC 16 is used for frame verification.
5.4 Response message timeout
As per the Modbus specification, each device can define its own maximum timeout for the response to be sent to a
request. The maximum timeout for the module is one second.
6 Application layer
The Application layer defines the type and format of the messages that will be sent.

6.3.4 Status table
The current status of the CoreSense module can be read by using either register 0x117 (analog signal) or
0x97:0x9A (digital alarm). Please use only one of the 2 registers to read the current status of the module.
Status Table is used to decode the “module status” in Modbus address register 0x97:0x9A shown in Table 11 in
Chapter 6.3.2. The code sent by the module for status is a number that can be indexed into the table to decode the
state of the module.
Register 0097:009A is showing less than 64 bits in the table below, because only the alarm IDs that belong to
Stream CoreSense are shown. This register supports not only Stream CoreSense but also other Emerson
CoreSense products (for example CoreSense in Scroll).

7 Troubleshooting
If the communication module does not respond, here is a list of general troubleshooting tips:
1. Check the wiring connection. Ensure the wiring is correctly connected and the connector is not loose.
2. Check the power to the CoreSense module. Check the power supply line and ensure the power is on and
the green LED is on.
3. Check the module network address. The address should match the address that the master has requested.
The valid addresses are 1 to 31. “0” is not a valid address.
4. Check your master data format setting. Ensure the master node data format setting to: RTU mode, 1 start
bit, 8 data bits, no parity bit, and 2 stop bits.
5. Check the master node baud rate setting. Set your master node baud rate as 19200 and then try to
communicate with the module. If the module does not respond, then set to 9600 baud rate and try it again.
Any third party PC debugging tool can also be used by sending a query for getting the firmware version number.
The response indicates the version number as 1.01R00 (this number is only an example and may change
according to models).
