Siemens 6ES7314-1AG14-0AB0

ECS rates the 6ES7314-1AG14-0AB0 as phase-out: still orderable, but on its way out. This is the time to plan, not panic.

  1. Active RolloutSold and supported normally
  2. Phase OutRetirement announced, still orderable
  3. CancellationNormal sale ended, spares may remain
  4. Total DiscontinuationNo manufacturer supply or repair

ECS stage: Phase Out.

Is the Siemens 6ES7314-1AG14-0AB0 being discontinued?

On ECS's lifecycle assessment, the 6ES7314-1AG14-0AB0 is in phase-out: still orderable for now, but on its way out.

Source: ECS lifecycle assessment, based on ECS's internal lifecycle data in Command Centre. Last checked . Always confirm a specific part's status with the manufacturer before buying or planning a migration.

What Phase Out means for you

The manufacturer is retiring the part, but you can still buy it. Nothing needs ripping out. Four things are worth doing while it is still easy: find every unit you run, make sure each has a current backup, decide whether to hold spares, and price the move.

How ECS defines Phase Out · all four lifecycle stages

Before replacing a PLC processor

We would secure a current, tested PLC program backup, record the programming software and version, and map the I/O, networks and intelligent modules connected to the controller.

CPU migrations can alter addressing, communications, memory behaviour or firmware requirements, so a newer processor in the same general family is not automatically a drop-in replacement. Proving that the program can actually be restored while the existing controller still runs is one of the most valuable checks a maintenance team can make.

Common questions about the 6ES7314-1AG14-0AB0

Is the Siemens 6ES7314-1AG14-0AB0 being discontinued?

On ECS's lifecycle assessment, the 6ES7314-1AG14-0AB0 is in phase-out: still orderable for now, but on its way out.

Can I still buy a 6ES7314-1AG14-0AB0?

Yes, through normal channels during the phase-out period. It is the cheapest point to buy any spares you want to hold.

How do I back up a 6ES7314-1AG14-0AB0?

It is programmed with S7 Simatic Manager. The exact software version and cable depend on the unit's firmware. ECS records both for every unit it captures, alongside a verified backup.

With a backup, a failed unit is hours. Without one, it is days.

A Capture audit finds every 6ES7314-1AG14-0AB0 on your site, takes a backup of each one it can reach, and records the software version and cable needed to restore it. When a discontinued unit fails and a replacement turns up, the program is ready to load.

  • Every device located, photographed and lifecycle-checked
  • Backups taken on the day, with software version and cable recorded
  • Findings report, plus a populated Command Centre
  • No production downtime
