PRODUCT DESCRIPTION
CM578-CN connects CANopen devices to AC500
ABB CM578-CN enables CANopen communication for the documented AC500 CPU families. It exchanges controller data through the terminal-base communication interface and connects to the fieldbus through a removable five-pin COMBICON connector.
Order 1SAP170800R0001 is the standard CM578-CN, distinct from the XC order. ABB datasheet revision 2 lists both variants as Classic. Preserve the installed CANopen configuration, node identities and applicable environmental conditions when evaluating a replacement.

BEFORE YOU BUY
Review node identity and the installed version
ACTUAL APPLICATIONS
Where CM578-CN integrates CANopen device profiles
ABB describes profiles for I/O, drives and encoders and explains the shared object-dictionary mechanism. The following are engineering scenarios based on that documentation, not named customer cases.
-
01 · REMOTE I/O
Map field-node process data
Integrate compatible digital or analog CANopen I/O nodes through their device descriptions. Preserve the object-dictionary mapping and valid node addresses in the controller project. Check the actual input and output behavior after the communication state has been established. -
02 · DRIVE PROFILES
Exchange drive-related information
Connect compatible CANopen drive devices using the applicable device profile and EDS identity. Validate the intended control and status mapping rather than relying on physical bus connection alone. Test the engineered sequence and equipment interlocks before automatic operation. -
03 · ENCODER DATA
Acquire configured encoder values
Read compatible CANopen encoder data through the specified device objects and project mapping. Confirm the actual encoder identity and interpretation of its reported values. Compare the received information with a controlled physical movement before accepting the measurement path.

CANOPEN PROFILE INTEGRATION
Preserve the object dictionary and node configuration
ABB CM578-CN enables CANopen communication for the documented AC500 CPU families. It exchanges controller data through the terminal-base communication interface and connects to the fieldbus through a removable five-pin COMBICON connector.
CANopen device descriptions identify communication parameters and device-specific objects. Record the correct EDS and node address for each connected device and verify that the application mapping uses the intended objects.
The standard CM578-CN uses the documented pin allocation with pin 5 unused. Keep the CPU-base 24 V budget distinct from the communication-bus current, and verify the selected rate, cable length and data-line termination.
Features:
- Match standard order 1SAP170800R0001
- Validate field-device EDS and object mapping
- Check node states and application data
The ABB CM578-CN requires verified CANopen node identities and object mappings before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
ABB datasheet 3ADR010018 revision 2, dated 2018-05-04, lists standard CM578-CN order 1SAP170800R0001 as Classic. It advises using Active products for new installation planning; obtain current migration guidance for a new design.
For an installed replacement, retain the CPU and terminal-base identity, CANopen configuration, EDS files and device addresses. Confirm that the supplied module is the standard version rather than assuming XC qualification from a similar housing.
Perform replacement with supply and process voltages isolated. Restore the recorded bus settings and then validate node states, process-data mapping and the actual connected device behavior.
Features:
- Record standard versus XC identity
- Preserve EDS files and node configuration
- Verify device data and application operation
The ABB CM578-CN requires replacement verification of its variant identity, CANopen objects and node configuration before commissioning.
DOCUMENTATION STATUS
Browse the Manuals, Datasheets, Official Documents, Links
Important Notice: The Amikon manual combines the exact CM578-CN hardware section with the standard-version pages from ABB revision 2. XC-only environmental pages are excluded. Confirm applicability to the installed controller version.
Features:
- CM578-CN documents distinguish NMT roles, EDS data and standard-version limits
- Software licensing and project backups remain the customer's responsibility
- Accessories are supplied only when listed in the quotation
Documentation for the ABB CM578-CN must match the intended CANopen device configuration and ordered variant; confirm manual availability in the written quotation.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about CM578-CN
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can a DeviceNet plug with power on pin 5 be reused unchanged on CM578-CN?
No. ABB identifies pin 5 of the CM578-CN CANopen connector as unused, with CAN_GND on pin 1. Do not transfer the DeviceNet power-pin assignment to this connector. -
Why are both 50 mA and 290 mA listed for CM578-CN consumption?
They refer to different supply interfaces. The revision-2 datasheet lists typically 50 mA at the CPU terminal-base 24 V supply and typically 290 mA over the communication-module bus. Use the value appropriate to the power budget being evaluated. -
Does a CANopen network capacity of 128 devices mean 128 slave addresses?
No. ABB describes one NMT master and up to 127 NMT slaves, with slave addresses from 1 to 127. The total device figure must not be used as a 128-slave allowance. -
What information does an EDS contribute to a CM578-CN project?
ABB describes the Electronic Data Sheet as the standardized representation of a CANopen device and its object dictionary. It identifies communication and device-specific functionality; match the EDS to the actual field device rather than treating it as the controller application. -
Does NMT master status mean only CM578-CN can transmit operational messages?
No. ABB explains that all devices can transmit in operational mode, while the master can change slave operating modes. CANopen master/slave terminology should not be treated as identical to a strictly polled bus architecture. -
Does an illuminated yellow STA lamp itself indicate a CM578-CN fault?
No. The dedicated LED table says STA on indicates that the CANopen master is transmitting data. The separate red ERR indicator reports a CANopen error. -
Does identical construction make the standard CM578-CN an XC module?
No. The standard order is 1SAP170800R0001; the XC order is 1SAP370800R0001. ABB assigns different system-data sections to the two variants, so environmental qualification must follow the actual ordered version. -
What does the Classic entry mean when considering CM578-CN for a new installation?
ABB revision 2 lists CM578-CN as Classic and advises using Active modules for planning and commissioning new installations. Review the current replacement path with ABB; the historical Classic entry is not an Active-status claim.
