PM591-2ETH FAQ

What distinguishes the two network interfaces on PM591-2ETH?They are independent Ethernet interfaces, not merely two switch ports on one interface. Preserve each interface's assigned network role and addressing when integrating the CPU.
Which mounting arrangement is required for PM591-2ETH?Use the dedicated dual-Ethernet terminal-base arrangement specified for this CPU. Confirm the actual base identity and connector layout before treating an existing station base as suitable.
What program-memory capacity is assigned to PM591-2ETH?The processor has 4096 kB of user program memory. Compare the compiled application with that allocation and assess user-data storage as a different resource.
How should the 5632 kB user-data allocation on PM591-2ETH be interpreted?The integrated user-data allocation is 5632 kB, with 1536 kB identified as saved. Plan working data and the values requiring retention separately from program storage.
Can the two PM591-2ETH Ethernet cables be swapped during maintenance?Do not swap them without checking the project arrangement. Identify which cable belongs to each independently configured interface and restore the correct address and network assignment.
Where are the PM591-2ETH Ethernet connections provided?The appropriate terminal-base arrangement provides two RJ45 Ethernet connections. Include the actual base and its supplied connectors in the hardware review instead of treating a bare CPU photograph as the complete station.
What power input applies to PM591-2ETH?Its specified supply is 24 VDC. Check the actual supply terminals, polarity and station power design before energizing the assembled processor and base.
How should existing serial wiring be transferred to PM591-2ETH?Compare the actual installed terminal diagram, electrical mode and device settings before moving conductors. Identify each used connection from the accepted station record rather than relying on a processor-family name.
Is the local PM591-2ETH display enough to validate a network migration?The LC display and function keys assist local diagnosis, but they do not replace network and application tests. Verify both intended network paths and the required control functions under the approved test plan.
What evidence completes a PM591-2ETH replacement?Keep the complete CPU and base identities, approved project version, two-interface connection record and functional test results together. These checks establish the accepted installation rather than assuming direct interchangeability from physical fit.
