Lifecycle status
Discontinued - and so is its designated successor (CIM). This is a chain discontinuation: the official upgrade path is itself already end-of-life.
Replacement paths, side by side
The decisive attribute in this vertical is software and runtime compatibility, not electrical specs. Read the compatibility column before the price column.
| Route | What | Price band | Availability | Compatibility — the dealbreakers | Shortlist |
|---|---|---|---|---|---|
| Official successor |
LOGO! CIM Siemens |
€281 across 1 EU distributor | Listed at Omnical, no stock shown; lead time on request |
Designed as the direct successor, but discontinued in turn. Choosing it means repeating this decision shortly. Why this matters ⌄ |
|
| Compatible third party |
Industrial modem / router Wachendorff |
Quoted on request; no public list price. | Not established in research |
Third-party mobile gateway. Not a LOGO! accessory - expect to redo the connection configuration rather than reuse it. Why this matters ⌄ |
|
| Compatible third party |
Industrial modem / router Phoenix Contact |
€756–864 across 2 EU distributors | In stock at DigiKey (1 pcs) |
Third-party mobile gateway. Connection configuration is rebuilt. Why this matters ⌄ |
|
| Compatible third party |
Raspberry Pi gateway Self-built |
Hardware cost is low; the cost is engineering and long-term maintenance. | Always available |
Named in the forum thread. Full flexibility, no vendor support, and you own the security patching. Why this matters ⌄ |
Where the research did not establish a figure, this page says so rather than estimating one. A number you cannot defend is worse than no number.
