Product Description (Detailed Explanation)

The FM 355-2 C is a 4-channel closed-loop control module that operates independently of the S7-300 CPU’s cycle time. This autonomous operation ensures that control loops remain stable and precise even if the main PLC program execution is delayed.

Equipped with a high-resolution analog-to-digital converter and integrated PID control algorithms, the module is optimized for continuous control applications. It provides analog outputs (4 to 20 mA or 0 to 10 V) to drive actuators such as modulating valves or heaters. The module also features a “Self-Tuning” function, which automatically calculates the optimal PID parameters ($K_p$, $T_n$, $T_v$) for the connected process.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Autonomous Operation: The module continues to control the process even if the CPU is in “STOP” mode or during a program download, preventing process disruptions.

• Integrated Self-Tuning: Simplifies the commissioning of complex loops by automatically identifying process characteristics and suggesting PID settings.

• High Precision: 14-bit resolution ensures extremely accurate sensing of temperature and pressure, reducing waste and improving product quality.

• CPU Offloading: By handling the math-intensive PID calculations locally on the module, the main PLC CPU is free to handle other logic and communication tasks.

• Universal Inputs: A single module can interface with various sensor types (J/K/S Thermocouples, Pt100, or 4-20mA signals) without needing external converters.

Precautions (Important Notes)

• Configuration Software: To configure this module, you must install the “FM 355-2 Configuration Package” for STEP 7 or TIA Portal. It cannot be programmed using standard ladder logic blocks alone.

• External Power: The module requires an external 24V DC power supply to operate its analog output circuits. Ensure this supply is fused correctly.

• Shielding: To maintain 14-bit accuracy, shielded cables are mandatory for all analog input and output signals. The shield should be grounded at the module’s terminal rail.

• Cold Junction Compensation: If using thermocouples, ensure the correct compensation method (internal or external Pt100) is selected in the hardware configuration to avoid temperature drift.

Product Applications (Typical Use Cases)

• Plastic Extrusion: Maintaining precise multi-zone temperature control on extruder barrels to ensure consistent polymer melt quality.

• Industrial Ovens & Kilns: Precise ramp-and-soak temperature profiles in glass manufacturing or ceramic firing.

• Boiler Pressure Control: Regulating fuel-to-air ratios and steam pressure in large-scale utility boilers.

• Chemical Reactors: Managing exothermic reactions where constant, high-speed temperature adjustment is critical for safety.

• HVAC Systems: Sophisticated pressure and flow control in large-scale cleanroom environments or data centers.
