Hardware and software
SIMATIC families and lifecycle status.
Status is only what the manufacturer says, with the source beside it. For a specific part, check its number in the manufacturer’s lifecycle tool.
| Family | What it is | Software | Status |
|---|---|---|---|
| SIMATIC S5 | S5-90U to S5-155U controllers | STEP 5 | Long out of production. Spares come from the surplus market. Plan an S5 to TIA Portal migration |
| SIMATIC S7-300 and ET 200M | Modular controller and its distributed I/O | STEP 7 V5.x (SIMATIC Manager) or TIA Portal | Orderable until Oct 1, 2023; cancelled Oct 1, 2025; spare parts planned until Oct 1, 2033. Source: Siemens Plan an S7-300 to S7-1500 migration |
| SIMATIC S7-400 (incl. H and F) | High-end and redundant controllers | STEP 7 V5.x, PCS 7, or TIA Portal | Check each part number’s lifecycle in SiePortal. New projects go to S7-1500. Plan an S7-400 to S7-1500 migration |
| SIMATIC S7-1200 | Compact controller | TIA Portal (STEP 7 Basic or Professional) | Current platform. |
| SIMATIC S7-1500 | Standard, failsafe (F), technology (T), redundant (R/H), ET 200SP CPUs, software controller | TIA Portal (STEP 7 Professional) | Current platform. |
| HMI | OP/TP panels, Comfort Panels, Unified Comfort Panels, PC stations | WinCC flexible (older), WinCC in TIA Portal, WinCC Unified | Mixed. Check the panel’s part number. |
| Drives | SINAMICS G120, G120C, S120, V90 | Startdrive (TIA Portal); STARTER and SCOUT on older systems | Current families. |
| Distributed I/O | ET 200SP, ET 200MP, ET 200pro, ET 200eco PN (and ET 200M, ET 200S on older lines) | Configured in the controller project | ET 200M: see S7-300 above. |
Before you send an RFQ
Siemens project files to send with an RFQ.
| Software or system | Send | How |
|---|---|---|
| STEP 5 | The whole project folder: the program file ends in ST.S5D, plus the other S5D files beside it | Zip the folder. |
| STEP 7 V5.x | A SIMATIC Manager archive (.zip) | SIMATIC Manager > File > Archive. |
| TIA Portal | A project archive (.zapNN, where NN is the version, e.g. .zap19) | Project > Archive. Tell us the TIA Portal version and update level. |
| Drives | The drive configuration, inside the TIA Portal project or as a STARTER archive | Include the drive part numbers and firmware. |
From the floor
Worth knowing first.
Match the software to the controller
TIA Portal opens a project only in its own version or newer, and an upgrade is one-way. Keep an archive of the version the plant runs.
PROFINET device names
A replaced PROFINET device has no name until it is assigned. Topology in the project, or "device replacement without exchangeable medium", lets the controller name it automatically.
Optimized blocks
S7-1200 and S7-1500 data blocks are optimized by default: symbolic access only. Absolute addressing from an HMI or another controller needs a standard (non-optimized) block.
Migrating off S5 or S7-300
S5 code goes through a converter to S7 first and still needs rework by hand. See how we stage an S5 migration or an S7-300 to S7-1500 migration.

Field notes
Answered on The Floor.
- PID_Compact on a 1500 — good in manual, oscillates in auto after a valve trim
- PROFINET device name lost after a switch replacement — ET200SP won't assign
- S7-300 to S7-1500 — what you keep in the DB and what you rewrite
- TIA Portal v19 license floating away mid-download
- GSDML version on an ET200SP doesn't match TIA — update the file or the module?
- S7-1200 web server is on — how much is too much to expose on a cell VLAN?
- S7-1500 watchdog after a TIA V19 download — cell stays in STOP
- First S7-1500H redundant pair — what bit you on switchover that the brochure skipped?
- WinCC Unified vs Comfort for a new line we have to support 15 years
- Motion in SCL or keep it in ladder so maintenance can still read it?
- S7-1500 OPC UA client — session error 3870_0600, UaExpert is fine
- Comfort Panel graphic list shows a cactus after a SiVArc generate
