The connection diagrams of different hardware modules are presented in this manual.
SMU615 overview 1MRS758580 C Figure 2: Example of the LHMI 2.4.1 LEDs The LHMI includes a dedicated Ready LED indicator and 11 matrix programmable LEDs on front of the LHMI. The LEDs can be configured with PCM600 and the operation mode can be selected via WHMI or PCM600.
1MRS758580 C SMU615 overview Figure 3: LHMI command push button and RJ-45 communication port Web HMI The WHMI allows secure access to the merging unit via a Web browser. When the Secure Communication parameter in the merging unit is activated, the Web server is forced to take a secured (HTTPS) connection to WHMI using TLS encryption.
SMU615 overview 1MRS758580 C • Locally by connecting the laptop to the merging unit via the front communication port. • Remotely over LAN/WAN. WHMI is enabled by default on the rear port and always enabled (cannot be disabled) on the front port. If the WHMI is accessed locally via the front communication port, the following features are available.

1MRS758580 C SMU615 overview events and changes in the merging unit. Both audit trail events and process related events can be examined and analyzed in a consistent method with the help of Event List in WHMI and Event Viewer in PCM600. The merging unit stores 2048 audit trail events to the nonvolatile audit trail.
SMU615 overview 1MRS758580 C PCM600 Event Viewer can be used to view the audit trail events and process related events. Audit trail events are visible through dedicated Security events view. Since only the administrator has the right to read audit trail, authorization must be used in PCM600.
1MRS758580 C SMU615 overview through these protocols. However, some communication functionality, for example, horizontal communication between the merging units, is only enabled by the IEC 61850 communication protocol. The IEC 61850 communication implementation supports all monitoring and control functions. Additionally, parameter settings and disturbance recordings can be accessed using the IEC 61850 protocol.
