What is Logsheet?
A logsheet is a paper-based or digital form commonly used in asset-intensive industries.
This form is used to record, collect, and retain equipment data during routine inspections, walkarounds, and regular checks of machinery and assets.
Each piece of equipment typically has its own dedicated logsheet. Maintenance and operations personnel use these forms—with predefined data fields—during routine rounds to record equipment-specific parameters such as temperature, vibration levels, flow rate, current (amperage), and similar metrics at scheduled intervals.
Collecting this information in logsheet forms—along with details such as the date of data entry, the person who recorded it, the approver, form ID, deviation levels, and more—provides maintenance and operations managers with a comprehensive overview of equipment conditions and the routine inspection activities performed.


Say goodbye to manual and paper-based logsheets.
What Is Logsheet Software and Why Does It Matter?
In many asset-intensive industries—such as power plants, steel manufacturing, refineries, petrochemicals, and beyond—routine logging and monitoring of key equipment performance parameters around the clock is essential. One of the core responsibilities of operations teams is to inspect critical equipment regularly and accurately record operational data such as temperature, vibration, pressure, or current.
Traditionally, many companies rely on manual data entry using paper-based logsheets. However, this method is time-consuming, prone to human error, and lacks the accessibility needed for timely data retrieval and effective analysis. Moreover, manually logged data often cannot be efficiently leveraged for triggering scheduled maintenance activities such as PM (Preventive Maintenance), CBM (Condition-Based Maintenance), or PdM (Predictive Maintenance). The sheer volume of recorded values and the need to sift through paper archives make data extraction both time-consuming and, in practice, nearly impossible.
The Pegahe Aftab Logsheet Software offers a reliable, efficient, and cost-effective solution to these challenges. Equipped with an Android application that supports both online and offline modes, it transforms the entire process of equipment data logging. From real-time data entry to report generation and actionable insights, the software delivers a fully integrated platform that automates the collection, storage, and application of operational data—helping organizations gain better control over asset health and maintenance planning.

The Power of Digital Logsheet and Checklist Registration
Recording Operational Parameters
You can record operational parameters for the equipment tree you've configured in your maintenance system—fully tailored to your needs and with no limit on the number of hierarchy levels.
Centralized User Management
You can define as many users as needed for the Android Logsheet app on handheld devices. The entire process—from logging in, entering values, and confirming them, to submitting data—is fully controlled and traceable.
Custom Logsheet Templates
You can include multiple parameters from different pieces of equipment in separate logsheet templates, fully customized to your needs. Define as many templates (logsheet form designs) as required—there’s no limit to how many you can create.
Process Design Engine
You can define, design, and implement the entire process of data entry, review, and approval for logsheet forms—customized for each individual logsheet template if needed—using the Process Design and Execution Engine of the Power Plant ERP. In essence, you own a logsheet system with powerful process management capabilities, fully tailored to your operational workflows.
Logsheet Issuance Management
You can define your logsheet templates as case-based or, alternatively, choose a periodic type and set the interval period. With this setup, the system will automatically issue logsheet forms on a regular, around-the-clock basis, allowing you to focus solely on entering the data. The system handles the issuance and scheduling of log sheets, ensuring that no entries are missed.
Self-Control Management
The Logsheet system is designed with Self-Control features. This means that whether in offline or online data entry mode, the system performs the necessary checks and provides relevant alerts to the user regarding unauthorized values, trip limits, alarm thresholds, and other critical conditions. These real-time validations ensure that data entered is within acceptable ranges, enhancing accuracy and preventing errors before they are submitted.
Android and Desktop Platforms
You can enter data for logsheet forms either through the Android system using handheld devices or via a desktop computer in a desktop environment. There are no technical limitations when it comes to regularly and systematically entering values into the logsheet forms. The system ensures seamless and flexible data entry across both platforms, allowing for efficient and consistent logging regardless of the device used.
Push Method for Issuance
The method used for issuing logsheet forms is PUSH. This means that the user doesn’t need to manually search for which forms to fill out, with what parameters, and at what time. Instead, the system automatically pushes the relevant logsheet forms to the user. The user simply needs to log in to their portal inbox or access the Android Logsheet system with their credentials to see the forms that need to be completed. This approach simplifies the process, ensuring that users always have the right forms available when needed.
Support for All Types of PMs (Preventive Maintenance)
You can use the operational parameters associated with equipment in the definition of various Preventive Maintenance (PM) types. Once the values recorded in the logsheet are confirmed, they will be processed according to the defined workflow and become available as equipment parameters for calculating PM due dates. This ensures that maintenance schedules are automatically generated based on real-time, validated data, allowing for accurate and timely maintenance actions.
Types of Android Devices
You can use the Android Logsheet system on any smart device, industrial or non-industrial, that is equipped with Android 5.0 or higher, without any hardware dependency on Pegahe Aftab or any other brand. This provides you with the flexibility to integrate the system across a wide range of devices, ensuring compatibility and ease of use regardless of the specific hardware.
Automatic Data Synchronization
You can synchronize data with the server automatically or at the user's request via the WiFi network. Data transfer from the handheld device will have no delay. Within just a few minutes and with ease, all recorded values will be made available to authorized users. This ensures quick and efficient access to up-to-date information across all devices.
Complete Management and Auditing
You can reduce the time between data entry by the operator and the review and approval of logsheet forms from several days to just a few minutes. All logsheet forms, once filled out, are synchronized and then undergo the defined review and final approval process. This streamlines the entire workflow, ensuring faster and more efficient validation of the recorded data.
