How to reset FloBoss S600+ | Easy Methods
Let me walk you through everything you need to know about resetting your FloBoss S600+, from gentle warm starts to nuclear-option cold starts, and when to use each one.
Understanding FloBoss S600+ Reset Types: Your Digital Toolbox
Before we dive into the nitty-gritty, you need to understand that the FloBoss S600+offers different reset options for different scenarios. Think of it like having multiple tools in your toolbox – you wouldn’t use a sledgehammer when a regular hammer will do.
Warm Start: The Gentle Giant
A FloBoss S600+ warm start is your first line of defense. It’s like giving your computer a gentle nudge rather than pulling the power cord. During a warm start, the S600+ preserves your configuration memory (SRAM) and keeps all your accumulated values intact.
When you initiate a warm start, you’ll see the “RESTARTING” message on your display. The system continues operation using the data stored in configuration memory just before the restart occurred. This means your totals, settings, and historical data remain untouched.
Perfect for:
- System lockups
- Minor software glitches
- Routine maintenance restarts
- When you want to preserve all current data
Cold Start: The Nuclear Option
A FloBoss S600+ cold start is the big gun in your arsenal. This procedure copies the configuration file from flash memory and replaces any online changes made since your last Config600 download or backup.
Here’s where it gets interesting – during a cold start, you can choose to keep or reset your cumulative totals, but only if the database structure hasn’t changed.
Essential for:
- After sending new configurations
- Recovering from corrupted databases
- Following firmware updates
- When warm start fails to resolve issues

Step-by-Step FloBoss S600+ Reset Procedures
Method 1: Warm Start Procedure
The warm start is automatic when you power up your S600+, but you can also initiate it manually:
- Power up the unit – When the S600+ first receives 24V DC power, it automatically performs initialization and self-test
- Look for “RESETTING” message – This appears briefly during startup
- Wait for “RESTARTING” display – This confirms the warm start is in progress
- Check for Main Menu – A successful warm start displays the Main Menu
If your S600+ can’t find a valid configuration during warm start, it’ll automatically display the Startup Menu instead – that’s your cue that you might need a cold start.
Method 2: Cold Start – Unpowered Method
This is my preferred method when the unit is already powered down:
- Locate the CPU module – Find bit link P2 on the CPU module
- Set the jumper – Move P2 to the closed (cold start) position
- Apply power – Energize your 24V DC supply
- Navigate the menu – The Startup menu will appear automatically
- Select COLD START – Choose option 1 from the Startup menu
- Handle totals – Press 1 to keep existing totals or 2 to reset them
- Confirm selection – Press 1 to confirm
- Wait for completion – You’ll see “CONFIGURING – PLEASE WAIT”
- Remove jumper – Critical: Remove the cold start jumper when done
Warning: Don’t forget step 9! Leaving the cold start jumper in place means any unexpected restart will trigger a cold start, potentially losing data. How to reset FloBoss S600+ | Easy Methods
Method 3: Cold Start – Powered Method
When your S600+ is running but needs a cold start:
- Access System Settings – From the Main menu, select SYSTEM SETTINGS
- Navigate to System Status – Select SYSTEM STATUS
- Enter change mode – Press CHNG
- Provide security code – Enter your security code when prompted
- Select Cold Start – Press 1 to select COLD ST, then 1 again to confirm
- Wait for restart – Look for “SYSTEM RESTARTING – PLEASE WAIT”
- Access Startup Menu – The Startup menu appears after reset
- Complete cold start – Select COLD START and follow steps 6-8 from Method 2
Pro tip: If the display doesn’t change after 30 seconds, power down the unit, wait at least five seconds, then reapply power.

Best Practices: Lessons from the Field
After years of working with FloBoss S600+ systems, here are my hard-earned recommendations:
Before Any Reset
Always create backups – Use Config600 to save your current configuration and document critical totals. I can’t stress this enough – I’ve seen too many engineers lose months of configuration work because they skipped this step.
Verify power quality – Ensure your 24V DC supply is stable and properly grounded. Voltage fluctuations during reset procedures can corrupt data or cause partial configurations.
Plan for downtime – Coordinate with operations teams. Even a simple warm start can take several minutes, and cold starts may require 15-30 minutes depending on configuration complexity.
During Reset Procedures
Follow sequences exactly – These procedures aren’t suggestions – they’re requirements. Deviating from the documented steps can lead to incomplete resets or system instability.
Monitor progress messages – Pay attention to display messages. They’re your primary feedback during reset operations.
Don’t rush – Resist the urge to power cycle if progress seems slow. Many engineers have created bigger problems by interrupting reset procedures.

Deeper Dive into How to Reset FloBoss S600+: Understanding the Internal Architecture
To truly master how to reset FloBoss S600+, it’s beneficial to understand a bit more about its internal architecture. The FloBoss S600+ is not just a collection of components; it’s a sophisticated system designed for robust data handling. At its heart, it contains a CPU module, various I/O modules for connecting to sensors, and different types of memory:
- SRAM (Static RAM): This is the volatile memory where the active configuration, accumulated totals, and real-time operational data are stored while the unit is running. It’s fast but loses its content when power is completely removed (unless backed up by a battery, which the S600+ typically has for short-term power loss). A warm start specifically targets this memory, refreshing the software without clearing the data.
- Flash Memory: This is non-volatile memory that stores the saved configuration file (the “master” configuration) and the firmware. When you download a configuration using Config600, it’s typically saved here. A cold start fundamentally involves copying this saved configuration from flash memory back into SRAM, effectively starting fresh with a known good state. This is crucial for understanding how to reset FloBoss S600+ when dealing with corruption.
- EEPROM: Electrically Erasable Programmable Read-Only Memory is often used for storing calibration data and certain critical system parameters that are rarely changed.
Understanding this memory hierarchy helps clarify why different reset types have different impacts on your data. A warm start is gentle because it’s primarily refreshing the SRAM while trusting its current contents. A cold start, conversely, overrides the SRAM with the stable flash memory version, which is why it’s more impactful on unsaved changes. How to reset FloBoss S600+ | Easy Methods
The Role of Checksums and Data Integrity in How to Reset FloBoss S600+
The integrity of your data within the FloBoss S600+ is paramount, especially in fiscal measurement. The FloBoss S600+ employs various mechanisms, including checksums, to ensure that configuration files and data blocks are not corrupted. When you perform a cold start, the system verifies the integrity of the configuration file stored in flash memory. If this checksum fails, it indicates a corrupted file, and the Flow Computer might revert to a default configuration or prompt for a new download.
This is a critical point when considering how to reset FloBoss S600+ after a system anomaly. If the cold start itself doesn’t resolve the issue, it could be that the source configuration in flash memory is itself corrupted. In such cases, the next step would be to re-download a known good configuration from your Config600 backup. This highlights the absolute necessity of maintaining regular and validated backups.

- Monitor Real-time Data: Access live flow rates, pressures, temperatures, and calculated values from anywhere with network access.
- Generate Reports: Pull daily, monthly, or custom reports for auditing and reconciliation without physically visiting the site.
- Diagnostic Pings: Remotely check communication status and network health, identifying connectivity issues before they escalate.
- Firmware Updates (Selective): While a cold start is mandatory after a firmware update, the initial firmware file transfer can often be done remotely, preparing the FloBoss S600+ for the physical cold start.
- Security Management: Remotely manage user access levels and security codes, enhancing the overall security posture of your Flow Computer network.
This expanded remote capability significantly reduces operational expenditure (OpEx) by minimizing travel and on-site technician hours. It also contributes to proactive maintenance, allowing engineers to diagnose and often resolve issues before they lead to full system downtime. Understanding these remote capabilities is key to leveraging the full potential of how to reset FloBoss S600+ and manage it efficiently. How to reset FloBoss S600+ | Easy Methods
