Core Specifications of the Coordinator Module

The 6ES5923-3UC11 belongs to the Siemens SIMATIC S5 family of coordinator modules. This intelligent card manages data traffic between the central controller and distributed I/O racks. Moreover, it suits legacy S5-115U and S5-135U systems that remain in active service.

Each module occupies a single slot in the central rack. Additionally, the unit weighs roughly 0.50 kg with its front connector installed. The front panel measures 20 mm in width and 130 mm in height, while the 3UC11 suffix defines the firmware and interface configuration.

Interface and Mounting Details

The 6ES5923-3UC11 slides into the S5 rack and connects to the backplane bus. Consequently, technicians complete replacement without rewiring field terminations. This module links the CPU to remote I/O racks through a serial cable. Therefore, it extends control capacity across distant cabinet sections.

A front connector provides secure cable termination and strain relief. Meanwhile, the compact housing fits standard S5 rack clearances.

Performance and Application Notes

Plant engineers deploy the 6ES5923-3UC11 to coordinate distributed I/O in legacy installations. Furthermore, the module manages data exchange at rates up to 1.5 Mbps. Its onboard firmware handles protocol timing without burdening the main CPU. Meanwhile, the backplane interface keeps bus communication synchronized across the rack.

The module stores no energy internally, since it draws power from the backplane. As a result, it adds minimal load to the S5 power budget.
