Details that decide whether a unit fits
| Component | Check beyond the part number |
|---|---|
| PLC CPU | Hardware revision, firmware version, memory card, project compatibility with your programming software |
| I/O and communication modules | Revision, bus/network type, slot or backplane compatibility |
| Frequency drives | Supply voltage, power rating, option cards, firmware and the parameter set your machine uses |
| Servo drives and motors | Matched drive–motor pairing, encoder type, firmware, cable sets |
| HMIs | Display size and mounting cut-out, runtime version, project transfer method |
Programs and parameters
A replacement CPU or drive usually needs your program or parameter backup. Tell us whether a backup exists; it changes which options are practical. We do not carry out programming or commissioning ourselves.
What to send with the request
| Information | Why it matters |
|---|---|
| Manufacturer and full part number, including suffixes and revision | A one-character difference can be a different voltage, firmware or mounting |
| A photo of the nameplate or label | Often more reliable than a typed number — and shows the revision |
| Quantity | Some items exist as single units only |
| Destination country and delivery address type (plant, warehouse) | Decides the route, import formalities and what can be quoted |
| The date you need it by, and whether a line is stopped | Changes which options are worth pursuing |
| Whether an alternative would be acceptable, and who approves it | An alternative is only proposed with evidence and your agreement |
| What it fits (machine, system, controller) | Helps confirm compatibility and identify replacements |
What EUROMEXA does — and does not do
| We do | We do not |
|---|---|
| Search for the part internationally against the exact part number and revision | Hold our own stock of parts |
| Ask for dated evidence that a specific item exists and what condition it is in | Repair or recondition parts in our own workshop (repairs go to specialist repair shops) |
| Explain the difference between an exact match, a confirmed replacement and an alternative | Claim to be an authorised distributor of any manufacturer |
| Quote one clear price to your border or your plant, with estimated import duties shown separately | Promise availability or a delivery date before it is confirmed for your order |
| Tell you when we cannot find it, or when a local distributor is the faster route | Supply safety-critical components, at least initially |
Questions and answers
- Can a newer firmware version replace an older one?
- Sometimes, sometimes not — it depends on the manufacturer and your project. We flag firmware differences and leave the decision to your engineer, with the documentation we found.
- Which manufacturers do you cover?
- We accept requests for any manufacturer. We do not claim special access to any brand; whether a part can be sourced is established for each request.
