Bachmann MX220 Series CPU Processor Modules

Configured for deterministic machine and motion control in M1 automation systems, the Bachmann MX200 Series (MX207, MX213, MX220) Processor Modules provide high-performance x86-based industrial computing with integrated power distribution for I/O backplanes.

Hardware Specifications

Industrial Control & Network Determinism

• Profinet / EtherNet/IP Deterministic Networks: The MX200 series integrates into deterministic industrial Ethernet topologies. With dual-port RJ45 configurations (MX213/MX220), the modules support precise timing for cyclical data exchange, ensuring minimal jitter for EtherNet/IP and related control protocols.
• Backplane Bus Communication Velocity Licences: These processors leverage high-speed interface backplanes to handle intensive cyclic process image updates. The architecture allows for efficient scaling of I/O density without compromising the scan cycle requirements of the attached modules.
• Firmware Flash Compatibility: The modules feature a generic build target framework across the entire MX200 family, facilitating seamless code portability and field-upgradable firmware updates to address network security and protocol stacks.
• Real-Time Multi-Tasking: The CPU utilizes priority-scheduled multitasking, enabling parallel execution of motion control, condition monitoring, and communication tasks. The runtime environment includes cycle monitoring and hardware watchdog timers to ensure operational integrity.

Model Matrix & Suffix Breakdown

• MX207: Entry-level processor (266 MHz), 1x Ethernet, standard RS232 interface.
• MX213: Enhanced connectivity (266 MHz), 2x Ethernet, expanded serial support (RS232/RS422/RS485).
• MX220: High-performance variant (433 MHz), 2x Ethernet, dual-mode serial connectivity, optimized for complex CNC and motion control tasks.

Frequently Asked Questions

Q: Are these CPU modules capable of running in environments exceeding +60 deg C?

A: No. The rated operating range is -30 deg C to +60 deg C. Operation beyond these limits risks internal component degradation and potential triggering of the processor thermal monitoring watchdog.

Q: Does the integrated power supply support external I/O expansion?

A: Yes. The CPU provides a rated power output for I/O modules (up to 18.25 W on the MX207). Ensure that the total current demand of connected I/O cards does not exceed the specified current limits for the +5 V, +15 V, and -15 V rails.

Field Installation Guidelines

• Mounting: Ensure the fanless module has adequate clearance (vertical orientation recommended) to permit natural convection airflow. The generous thermal design requires unobstructed air intake/exhaust paths to maintain optimal junction temperatures.
• Grounding: Bond the module chassis to the cabinet earth ground. This provides the necessary return path for the integrated EMI suppression filters and ensures electrical stability during backplane signal high-speed transitions.
• Storage Media: When using the CompactFlash or PC-Card slots for data logging or application storage, ensure cards are inserted/removed only when the module is in an initialized or safe state to prevent file system corruption within the 64 MB internal storage partition.
