Greetings, We have a SIS CPU 417-4H in redundant service that will not go into run mode with it's partner. We refer to this processor as SIS CPU-B, shown on the right-hand side of the rack in the attached photo on page 1 of the Word document; SIS CPU-A is shown on the left-hand side. The warning lights are Error LED (EXTF) and Error LED (REDF). The order number/description is 6ES7 417-4HT14-0AB0 w/ firmware V 4.5.3 and boot loader Firmware expansion V 4.5.1. A description of this order number/firmware was retrieved directly from "Properties" using Simatic Manager as follows: "Redundant and fail-safe capable, work memory 15MB code and 15MB of data; 0.018 ms/1000 instructions; 16KB DI/O; 64 connections; 1*DP/MPI, 1*DP and 2 receptacles for H Sync modules; supports PROFIsafe V2; firmware V4.5" We run PCS7 version 8.1 SP1 for our DCS. The power supply had the amber light indicating a battery problem, so the battery was changed and the power was cycled on this redundant rack, and did not go into run mode after booting up. We then exchanged the power supply in SIS Rack-B for a spare, to eliminate the power supply as being the cause of the issue. This did not solve the problem of SIS CPU-B not going into run mode. The attached Word document contains messages from the Diagnostic Buffer, that was retrieved using Simatic Manager/ Hardware Config/ Module Information dialog, located in the Diagnostics Buffer tab. Among the messages of interest is the following: " Event 8 of 323: Event ID 16# 530D New startup information in STOP mode Startup prevented by: - STOP request exists - Cold restart or warm restart necessary Startup information: - Time for time stamp at the last non backed up power on - Single processor operation Current/last startup type: - Delayed connection repeat after time error for H CPUs Permissibility of certain startup types: - Manual warm restart permitted Last valid operation or setting of automatic startup type at power on: - No startup type/following memory reset Operating mode: STOP (internal) Event occurred in the standby CPU in rack 1 Incoming event 10:17:16.676 PM 08/28/2020 (Coding: 16# 530D F104 C777 0041 000E 0700) " The full text file .txt diagnostic is also attached. NOTE: Several Additional observations : are added in succession to this opening message for the purpose of adding additional attachments and comments to support evidence of the problem. We think we may have a hardware failure in this CPU. Thank you in advance to the forum members and SME's for any suggestions or comments how we might solve this problem. Douglas Warner

Additional observations : A video snapshot showing the SIS Racks A & B. Notice that CPU-B on the right has a solid "Stop" LED lit. To best view this video, zoom in and place video into repeat mode and then Play. AttachmentD75A23F9-E198-42DE-9A27-C9DDFD5F94C3.MOV (345 Downloads) |
