EtherNet/IP and Modbus TCP Communication Architecture

The LTMR100EBD integrates Ethernet communication through an RJ45 interface using EtherNet/IP and Modbus TCP protocols. The controller exchanges motor operating data, diagnostic information, fault records, and control commands with automation systems through Ethernet IEEE 802.3 communication.

The TeSys T controller supports deterministic data transfer for motor management functions, including current monitoring, trip context information, event recording, operating time counters, and motor control command logging.

Firmware compatibility is managed through the TeSys T firmware package supporting Ethernet, Profibus, CANopen, DeviceNet, and Modbus communication variants.

Frequently Asked Questions

Q: What motor parameters are measured by the LTMR100EBD?
A: The controller measures phase currents I1, I2, and I3 RMS, average current, earth fault current, temperature, imbalance current, and related motor operating conditions.

Q: Does the LTMR100EBD provide direct Ethernet communication?
A: Yes. The controller provides EtherNet/IP and Modbus TCP communication through an Ethernet IEEE 802.3 RJ45 interface.

Q: What type of logic interfaces are available on this controller?
A: The unit provides 6 logic inputs, 3 relay logic outputs, and a dedicated relay output for fault signaling.

Field Installation Guidelines

Install the LTMR100EBD on a suitable control panel mounting structure with sufficient clearance for terminal access and Ethernet cable routing.

Connect the 24 VDC supply according to the specified polarity requirements. Maintain separation between communication wiring, motor power conductors, and high-current switching circuits to reduce electrical interference.

Use shielded Ethernet cabling where required by the installation environment and connect cable shields according to the plant grounding practice. Verify terminal tightening torque and conductor preparation before commissioning.

Current sensing wiring must follow the motor circuit configuration requirements. Confirm phase conductor routing through the integrated current transformers and verify earth fault sensor connections before applying operating voltage.

The LTMR100EBD product is scheduled for discontinuation on Sep 30, 2026, with end-of-service on Jan 31, 2027. Recommended replacement groups include TeSys Tera components such as LTMTEBD with compatible current sensor modules.
