Product Description
ABB PM5670-2ETH 1SAP151000R0378 is an AC500 processor module with 160 MB of program memory, a 24 V DC terminal-base supply and a memory-card slot. It executes the control application while the terminal base provides the physical connection to the local I/O bus, Ethernet, CAN and serial communication paths.
Across its network boundary, ABB PM5670-2ETH 1SAP151000R0378 provides two independent RJ45 Ethernet interfaces. The separated ETH1 and ETH2 paths can support control-system communication, online access, Modbus TCP, the integrated web server and other enabled Ethernet services without treating the two connectors as one unmanaged switch.
For cabinet assembly, ABB PM5670-2ETH 1SAP151000R0378 is paired with a TB56xx-2ETH terminal base selected for the required communication-module capacity. COM1 is configured for RS-232 or RS-485 as needed, while the station power calculation must include the processor, terminal base, communication modules and connected I/O rather than the processor current alone.

03
Communication and Connectivity
ABB PM5670-2ETH 1SAP151000R0378 separates controller communication into distinct physical paths. The useful planning question is not merely which protocol appears in the data sheet, but which connector, network and reference potential carries each exchange in the finished station.
Serial and Field Paths
Select RS-232 or RS-485 for COM1, apply the matching wiring practice, and keep CAN and local I/O-bus connections separate from the serial-port record.
Service Allocation
Reserve sockets and enabled services for online access, Modbus TCP, the web server or other configured protocols instead of assuming every service can use unlimited simultaneous connections.
04
Installation Highlights
ABB PM5670-2ETH 1SAP151000R0378 installation is organized as a controlled sequence: confirm the matching terminal base, assemble the station without power, then commission the supply and communication paths one at a time.
Select the Terminal Base
Match ABB PM5670-2ETH 1SAP151000R0378 to a TB56xx-2ETH base with enough communication slots. Record the terminal-base article and hardware revision before mounting so the controller and base remain one traceable assembly.
Assemble Without Power
De-energize the 24 V DC supply, seat the terminal base on the rail, align the processor with its guides and lock the module without forcing the connector. Check that adjacent expansion modules do not exceed the planned station load.
Commission in Sequence
Verify polarity and protective wiring first, then energize the station, confirm display and status indications, assign separate Ethernet subnets and test COM1, CAN and I/O communication against the saved ABB PM5670-2ETH 1SAP151000R0378 project.

Frequently Asked Questions
Q01How can I distinguish the current ABB PM5670-2ETH 1SAP151000R0378 from the earlier hardware revision?
Use the full ABB PM5670-2ETH 1SAP151000R0378 reference when requesting the unit. It identifies processor-module revision 3, while the earlier 1SAP151000R0278 record belongs to revision 2 and should not be substituted silently in a project record.
Q02Which terminal base should be checked before installing ABB PM5670-2ETH 1SAP151000R0378?
ABB PM5670-2ETH 1SAP151000R0378 belongs with the TB56xx-2ETH terminal-base family. Confirm the required communication-slot count against TB5610-2ETH, TB5620-2ETH, TB5640-2ETH or TB5660-2ETH, and keep the terminal-base revision requirement in the same ABB PM5670-2ETH 1SAP151000R0378 configuration record.
Q03Can both Ethernet ports on ABB PM5670-2ETH 1SAP151000R0378 be placed in one subnet?
Plan ETH1 and ETH2 on ABB PM5670-2ETH 1SAP151000R0378 as independent interfaces in different subnets. The default PM56xx-2ETH arrangement separates the two networks, so duplicate or overlapping address plans should be corrected before commissioning ABB PM5670-2ETH 1SAP151000R0378.
Q04What should be reviewed when an ABB PM5670-2ETH 1SAP151000R0378 project uses COM1?
Record whether ABB PM5670-2ETH 1SAP151000R0378 COM1 is wired as RS-232 or RS-485, then check termination, reference potential and the intended protocol against that selection. This avoids treating the shared ABB PM5670-2ETH 1SAP151000R0378 COM1 connector as two simultaneous serial channels.
Q05Why does the ABB PM5670-2ETH 1SAP151000R0378 power calculation need more than the processor current?
The ABB PM5670-2ETH 1SAP151000R0378 processor alone has a lower typical current than a completed station. Build the supply calculation from the ABB PM5670-2ETH 1SAP151000R0378 terminal base, communication modules and I/O population so the configured load remains within the documented station value.
Q06What information helps resolve an ABB PM5670-2ETH 1SAP151000R0378 replacement enquiry quickly?
Send the ABB PM5670-2ETH 1SAP151000R0378 identifier, processor revision, terminal-base type, firmware context and required quantity together. Keeping those ABB PM5670-2ETH 1SAP151000R0378 details in one enquiry prevents a related PM56xx variant or incompatible terminal-base record from being selected.
