Page 3: Introduction
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. -
Page 4: Modbus Type Identification
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 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). -
Page 7: Labelling
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 Connectors A three-position screw cable connector is used for Modbus communication. -
Page 8: Data Link Layer
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). -

- Page 17 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).
- Page 18 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.
