With proactive network monitoring
Most network failures don't come out of nowhere. Jitter, dropouts, and creeping degradation show up long before the line stops. Continuous monitoring catches them while they're still a maintenance ticket, not a shutdown.
A conservative starting point. Plants with 24/7 monitoring routinely resolve the majority of emerging faults during planned maintenance windows instead of unplanned stops. Adjust to match your environment.

Downtime doesn't start when the line stops
It starts weeks earlier, in the network. Here's why proactive beats reactive.
Failures announce themselves
Packet jitter, retries, dropouts, and signal degradation on PROFINET, PROFIBUS, and EtherNet/IP networks typically precede a hard failure. Continuous monitoring turns those whispers into work orders before they become shutdowns.
Permanent, non-invasive watch
Panel-mounted tools like the PROFINET-INspektor® NT and PROmesh managed switches monitor your network continuously without touching production traffic, and alert your team the moment quality drifts out of spec.
Find faults fast when they do happen
When an incident does occur, precise diagnostics point you to the exact device, port, or cable segment, replacing hours of trial-and-error troubleshooting with a targeted fix.
Send these numbers to your manager
Approvals move on numbers, not opinions. This drops your results into a ready-to-send email with the math laid out, so the person who signs off can see the cost of doing nothing.
Frequently asked questions
What counts as "downtime" here?
Total time from the moment production is impacted until the line is stably running again, including troubleshooting, fault-finding, repair, restart, and ramp-up. In many plants, finding the fault takes longer than fixing it, which is exactly where network diagnostics pay off.
I don't know our cost per hour of downtime. What should I enter?
Most teams have never had finance sign off on a number. Build a working figure from four inputs: lost units per hour multiplied by contribution margin per unit, plus idled labor, plus scrap and rework from the stop and restart, plus any expedited freight or contractual penalties you would actually incur. If you only have one of those, start with lost throughput. The result will be conservative, which is usually the right way to walk into a budget conversation.
How accurate is this calculator?
Every figure comes from your inputs except one: the share of incidents that early detection prevents, which starts at 60% and is fully adjustable. There are no industry averages baked in behind the scenes. Treat the output as a defensible baseline for internal discussion, not a substitute for a site assessment. For a validated number, our team can perform a network health assessment on site.
Where does the "incidents prevented" number come from?
Most communication failures on industrial networks develop gradually. Degrading cables, EMC interference, failing ports, and creeping load issues produce measurable symptoms well before a stoppage. Continuous monitoring detects these early so they can be fixed during planned maintenance. Networks with clean physical infrastructure and stable load tend toward the lower end of the range; older installations with mixed cable vintages and heavy VFD environments toward the upper end. Set the slider to match your plant.
Which networks does this cover?
The calculator models any unplanned stop, whatever the cause. InduSol's diagnostic and monitoring tools target the OT network layer specifically: PROFINET, PROFIBUS, EtherNet/IP, EtherCAT, AS-i, CAN, IO-Link, and industrial Ethernet. That's where physical-layer and communication faults sit, and they're among the most common and most preventable causes of downtime.
We already have managed switches and PLC diagnostics. Doesn't that cover it?
Those tell you a station dropped. They rarely tell you why, and almost never tell you it was coming. Switch counters and controller diagnostics report at the logical layer, after the fault has already reached the process. Physical-layer degradation, jitter, EMC coupling, and marginal signal quality sit below that threshold and are visible only with dedicated network diagnostics.
What would monitoring cost, and how fast does it pay back?
Scope depends on how many network segments you need visibility on and whether you are monitoring permanently or diagnosing periodically. For most single-line installations the investment is a fraction of one avoided stoppage, which is why payback is usually measured in incidents rather than years. Send us your calculator results and we will scope a configuration against your actual network.
