Siemens S7-1200 G2 and Samkoon PLC: task-layered technical selection guide
Compare S7-1200 G2 with Samkoon FGR, FAs and PRO PLC candidates by I/O, motion, PROFINET, safety, expansion and software.
Short answer
What does this page recommend?
A technical alternative, not a drop-in substitute
Samkoon FGR can be a technical candidate for compact I/O control, FAs for higher built-in I/O and Ethernet needs, and PRO for pulse/motion-intensive duties. No equivalence is claimed unless S7-1200 G2 PROFINET, fail-safe, motion, OPC UA and TIA integration requirements are met at exact-CPU level.

| Validation area | Siemens SIMATIC S7-1200 G2 | Samkoon / ProControl candidate |
|---|---|---|
| CPU and program scope | S7-1200 G2 scales memory, performance and interface capacity across CPU 1212C/1214C/1215C G2 classes; exact features depend on the CPU code. | FGRB, FAS-32MT-AC-E and PRO occupy different performance/I/O layers. Program memory, cycle time and instruction scope are measured with the running application load. |
| Built-in I/O and electrical design | S7-1200 G2 compact CPU options include built-in DI/DO and analogue functions on some variants; transistor/relay and supply are determined by the full code. | FGRB is in the 8/8 class and FAS-32MT-AC-E in the 16/16 transistor class; NPN, SINK/SOURCE, commons, load current and AC/DC supply are verified from diagrams. |
| Motion and high-speed I/O | S7-1200 G2 is positioned with Siemens motion-control architecture and technology objects; axis, kinematics and CPU limits depend on the exact configuration. | Official FGRB and FAs pages list 200 kHz pulse outputs; PRO is a candidate for heavier motion. Pulse direction, interpolation, axis count and jitter are proven by PoC. |
| Industrial network and data | S7-1200 G2 provides PROFINET, Siemens-device integration, web/OPC UA and secure-connectivity functions in a CPU/firmware context. | FAS-32MT-AC-E is in the Ethernet Modbus TCP/IP class; exact FGRB and PRO ports are selected separately. PROFINET or OPC UA support is not assumed. |
| Safety and expansion | Fail-safe CPU/functions and Siemens expansion architecture in the S7-1200 G2 family can form part of the project's safety integrity. | A standard Samkoon PLC is not treated as a safety PLC. Safety is designed with a separately certified relay/PLC; I/O and module-expansion limits are verified per exact model. |
| Software and migration | S7-1200 G2 is a system comprising hardware, TIA Portal program, technology objects, symbols, diagnostics and any safety project. | The SamSoar project is rewritten; Siemens code, function blocks, hardware configuration and safety do not transfer automatically. I/O, timing, motion, communications and fault behaviour are accepted in FAT. |
Suitable scenario
When is it worth evaluating?
- Compact machines where fail-safe and Siemens-specific PROFINET/technology objects are not mandatory
- New designs where I/O, Modbus TCP and pulse duties can be covered by an exact Samkoon model
- Modernisations where PLC software, panel wiring and safety architecture can be redesigned
Migration gate
Before making a decision
- Record the full S7-1200 G2 CPU, signal/communication modules and firmware version.
- Extract program memory, cycle, DI/DO/AI/AO, HSC/PTO, motion axes and safety functions.
- Inventory PROFINET devices, telegrams, OPC UA/web/API and diagnostics use.
- Verify electrical, performance, expansion and protocol scope for the exact Samkoon model from official sources.
- Test I/O, motion, network loss, timing, fault recovery and the safety chain in a wired FAT.
Frequently asked
Clear answers about alternatives and migration
Is this a drop-in replacement?
No. It is not a direct substitute until exact model, electrical, protocol-role, mechanical, software and certification checks pass.
What should I provide for selection?
The exact existing code, diagram or I/O list, PLC/network data, supply, environment and special functions in use.
Can an S7-1200 G2 program be converted to a Samkoon PLC?
No automatic, reliable one-to-one conversion is assumed. Requirements, I/O and state machines are extracted; the program is reimplemented in SamSoar and passes timing and fault tests.

This content compares manufacturer-published data under the same project requirement; it does not guarantee direct substitution or project compatibility. ProControl engineering must validate exact model, revision, protocol, electrical, safety and environmental conditions.
