Schneider Electric AS-B-36L SXWASB36X10002 SmartX Server

Schneider Electric AS-B-36L (SXWASB36X10002) SpaceLogic SmartX Automation Server

The Schneider Electric SpaceLogic AS-B-36L (MPN: SXWASB36X10002) is an integrated, high-density edge server and field controller engineered for EcoStruxure Building Operation (EBO) architectures. Combining central processing, dual-port Ethernet switching, extensive onboard I/O capacity, and native multi-protocol routing (BACnet/IP, BACnet MS/TP, Modbus TCP, and Modbus RTU) into a single compact DIN-rail footprint, the AS-B-36L serves as a standalone building controller or a distributed plant room processing node.

Designed for demanding commercial and marine automation infrastructures, the AS-B-36L processes control logic locally, trends historical data, triggers alarms, and delivers full Web Services connectivity without requiring constant supervisory host intervention.

Key Features

1. All-in-One High-Density Architecture: Integrates 36 point-configurable I/O channels (universal, digital, triac, and electro-mechanical relays) with a high-speed automation engine in a single space-saving enclosure.
2. Dual-Port Managed Ethernet Switch: Facilitates daisy-chain line or Rapid Spanning Tree Protocol (RSTP) ring topologies without necessitating third-party external field switches.
3. Native Multi-Protocol Gateway Engine: Concurrently bridges, manages, and maps BACnet/IP, BACnet MS/TP, Modbus TCP, and Modbus RTU networks directly to EcoStruxure Building Operation.
4. Autonomous Edge Operations: Retains full trend log records, schedule matrices, and critical multi-level alarm handling internally within robust FRAM/eMMC non-volatile storage during network severance.
5. Pluggable Two-Piece Maintenance Base: Permits permanent pre-wiring and terminations to remain completely intact during electronics module servicing or replacement, minimizing system downtime.

Frequently Asked Questions

What is the main functional difference between the AS-B-36L and the AS-B-36H?

The AS-B-36L is the standard programmable automation controller without front-panel manual switches. The AS-B-36H includes physical Hand-Off-Auto (HOA) toggle overrides and analog override potentiometers with a front LCD screen for direct local maintenance.

Can the AS-B-36L operate independently if communication with the main EBO enterprise server drops?

Yes. The AS-B-36L executes all programmed control algorithms, scripts, alarm limits, and scheduled switching cycles locally. Data trends and audit records are preserved inside the controller’s onboard memory and synchronize back to the EcoStruxure Enterprise Server once communication is restored.

Can the universal I/O channels (Ub/Uc) handle active 4–20 mA transmitter loops?

The universal I/O channels configured as type Ub natively measure 0–20 mA current loops using internal precision shunts. For 2-wire loop-powered 4–20 mA sensors, an external 24 VDC auxiliary loop power source must be wired in series with the transmitter and the universal input channel.

How do the two integrated Ethernet ports operate?

The dual Ethernet ports function through an internal managed switch. They can be configured in a linear daisy-chain topology to minimize network cabling runs, or in a Rapid Spanning Tree Protocol (RSTP) ring configuration to provide communication fault tolerance.

What type of backup does the controller utilize to retain system time during an outage?

The unit utilizes a maintenance-free supercapacitor backed real-time clock (RTC), eliminating the need for periodic lithium coin-cell battery replacements while maintaining clock operation for at least 7 days of complete power loss.
