Technical Parameters & Selection Guide

Selection Criteria: Choose the 6ED1052-2MD00-0BA6 when your application requires 12/24V DC operation with relay outputs for switching inductive loads or high-current devices. For applications needing 230V AC supply voltage, consider the LOGO! 230RC variant. If Ethernet connectivity is essential for remote access or SCADA integration, evaluate the 12/24RCE model with built-in Ethernet interface. For applications exceeding 8 inputs or 4 outputs, plan for LOGO! expansion modules which connect seamlessly to the base unit.

Extended Capabilities & Integration

Modular Expansion Architecture: Add up to 8 expansion modules for analog inputs (0-10V, 4-20mA), additional digital I/O, or specialized functions like PT100 temperature measurement. Hot-swappable module design allows system upgrades without rewiring existing connections.

Communication Options: Optional CM modules enable Ethernet/IP, Modbus RTU/TCP, and KNX protocol support for integration with building management systems, SCADA platforms, and IoT gateways. Web server functionality provides browser-based monitoring and control without dedicated software.

Advanced Programming Functions: Built-in PID control, astronomical clock (sunrise/sunset calculation), data logging, and recipe management extend capabilities beyond simple logic control. LOGO! Soft Comfort software includes simulation mode for offline testing before deployment.

Text Display Integration: Connect LOGO! TD text displays for custom operator interfaces with multi-language support, parameter adjustment, and alarm acknowledgment. Ideal for OEM machines requiring user-friendly HMI without full-scale touchscreen investment.

Frequently Asked Questions

Q: How does the LOGO! controller compare to traditional relay panels for cost and reliability?
A: The 6ED1052-2MD00-0BA6 typically reduces installation costs by 40-60% compared to equivalent relay logic through simplified wiring and reduced panel space. Reliability improves significantly as there are no mechanical relay coils to fail in the control logic—only the output relays which are rated for 10 million operations. Program changes take minutes versus hours of rewiring, reducing commissioning and modification costs substantially.

Q: What programming knowledge is required to configure this logic module effectively?
A: Basic familiarity with ladder logic or function block diagrams is sufficient for most applications. The LOGO! Soft Comfort software provides drag-and-drop programming with pre-built function libraries for timers, counters, and common automation tasks. Most users complete initial training in 2-4 hours. For simple applications, direct keypad programming is possible without a PC, though software programming is recommended for complex sequences.

Q: Can this controller handle motor starting applications and what are the inductive load limitations?
A: The relay outputs are rated for 10A resistive loads but should be derated to 3-5A for inductive loads like motor contactors and solenoid valves. For direct motor control, use the relay outputs to drive appropriately-sized motor starters or contactors rather than connecting motors directly. The outputs include arc suppression for extended contact life when switching inductive loads within rated parameters.

Q: Is remote monitoring and control possible with this base model?
A: The 6ED1052-2MD00-0BA6 base unit does not include built-in Ethernet or wireless connectivity. However, you can add a LOGO! CMR communication module to enable Ethernet, Modbus, or cloud connectivity for remote access. Alternatively, consider the 12/24RCE variant which includes integrated Ethernet. Both options support web-based monitoring and control through standard browsers.

Q: What happens to the control program and real-time clock during power outages?
A: The program and all parameter settings are stored in non-volatile EEPROM memory and are retained indefinitely without power. The real-time clock continues running for approximately 80 hours during power loss using an internal supercapacitor (no battery required). Upon power restoration, the controller resumes operation based on configured startup behavior—either continuing from the last state or executing a defined initialization sequence.

Q: How do I expand the system if I need more inputs or outputs in the future?
A: The 6ED1052-2MD00-0BA6 supports up to 8 expansion modules connected via the right-side expansion port. Available modules include digital input/output expansion (DM8, DM16), analog input modules (AM2 AQ, AM2 PT100), and communication modules (CMR, CMK). Modules are hot-swappable and automatically recognized by the base unit. Total system capacity can reach 24 digital inputs, 20 digital outputs, and 8 analog channels depending on module selection.
