Can you supply discontinued SIMATIC S5 and S7-300 parts?

Yes — that is a large share of what we do. SIMATIC S5 has been out of production for many years, and the S7-300 and its I/O have moved into Siemens’ obsolete range, so both are sourced from surplus rather than a distribution channel. Send the MLFB order number and we will confirm the condition options, price and lead time.

What is an MLFB number, and do I need one to get a quote?

The MLFB is the Siemens order number printed on the module — the string beginning 6ES7, 6AV, 6SL or 6SN. It identifies the exact variant, so quoting from it is both fastest and most accurate. If you do not have it, send a photo of the module label or describe the rack and we will identify the part for you.

Which Siemens ranges does your catalogue cover?

SIMATIC S5 and S7 — including S7-200, S7-300, S7-400, S7-1200 and S7-1500 — plus distributed I/O, SIMATIC HMI panels, SIMATIC NET communications, SINAMICS and MICROMASTER drives, SIMODRIVE and SIMOTICS for machine tools and motors, SITOP power supplies, CNC hardware and RFID systems.

My MICROMASTER drive failed and Siemens says it is obsolete. What are my options?

Usually three: a like-for-like replacement from surplus, a repair of your existing unit, or a move to the SINAMICS range that superseded it. A like-for-like swap avoids re-engineering the panel and re-entering the parameter set, which is why most people start there. Tell us the drive rating and the MLFB and we will set out what is realistic.

Are your Siemens parts genuine, and what warranty applies?

They are Siemens-manufactured units from surplus, overstock and decommissioned plant. We are not an authorised Siemens distributor, so rather than the manufacturer’s warranty, every unit — new, refurbished or tested used — carries our own 1-year warranty and is bench-tested before it ships.

Can you repair a Siemens drive, CPU or HMI panel?

Often, yes. SINAMICS and SIMODRIVE drives, S5 and S7 CPUs and power supplies, and SIMATIC HMI panels are the units we see most. Send the MLFB and the fault symptoms from our Repair page and we will confirm whether it is repairable, along with turnaround and price.

Do you supply SIMODRIVE and SIMOTICS parts for machine tools?

Yes. SIMODRIVE drive modules, SIMOTICS motors and the CNC hardware around them are all in the catalogue. Machine-tool spares are configuration-sensitive, so send the MLFB from the unit itself and, where you have it, the machine model — the same nominal module can differ by firmware or revision.

Can you quote a whole list for a panel refit or a spares holding?

Yes, and it is usually the better way to buy. Send the list as a spreadsheet or paste it into a quote request with quantities, and we will come back with a line-by-line quote showing the condition options and lead time for each part, so you can see where a refurbished unit saves money and where it does not.

Manufacturer

Siemens

Siemens SIMATIC is the most widely installed PLC platform in factory and process automation, spanning S7-1500, S7-1200, S7-300 and S7-400 controllers alongside SINAMICS and MICROMASTER drives, SIMATIC HMI panels and SITOP power supplies. CMP Automate carries these families plus discontinued SIMATIC S5 and SIMODRIVE parts that keep older lines in service. Stock is tested under power and backed by a 1-year warranty, with worldwide shipping from Dubai.

CNC(488)Numerical control hardware for machine tools, centred on the Siemens SINUMERIK and SIMODRIVE families. CNC parts are frequently discontinued long before the machines they control are retired, so refurbished and tested used units are a practical route to keeping a machine in production. All items are tested under power before dispatch.Drives, Motors & Circuit Protection(9792)Variable frequency drives, servo and motion hardware, motors and circuit protection from ABB and Siemens. This category covers ACS and ACS800 drives, SINAMICS and MICROMASTER inverters, SIMOTICS motors and SACE breakers, in new, refurbished and tested used condition. Obsolete and superseded models are stocked specifically for plants that cannot requalify a replacement.General Automation(1134)Broad-range automation hardware that spans control, sensing and power: relays, contactors, terminal hardware, interface modules and field devices from ABB, Siemens and SICK. These are the components that keep an existing panel serviceable rather than the headline controllers. Stock covers current parts and discontinued items still needed for maintenance.HMIs & Industrial PCs(3114)Operator panels, touch terminals and industrial PCs from Siemens and ABB, including the SIMATIC HMI Comfort and Basic ranges. Panels are supplied new, refurbished and tested used, with obsolete models kept for machines whose project files cannot be rebuilt for current hardware. Each screen and touch layer is tested before dispatch.I/O & Signal Modules(3264)Digital and analogue input/output modules, signal conditioners and function modules for rack- and rail-mounted control systems. This is typically the first place a failure shows up and the part most often needed at short notice, so it is stocked deep across Siemens and ABB platforms. Refurbished and tested used modules are available where new stock is discontinued.Industrial Communication(3768)Fieldbus and industrial network hardware — PROFIBUS and PROFINET interfaces, communication processors, gateways, repeaters and media converters. CMP Automate stocks SIMATIC NET and comparable ABB and SICK communication parts for both new builds and legacy segments that still run older protocols. Every unit is tested before dispatch and warranted for 2 years.PLC Systems(1464)Programmable logic controllers and their CPUs, racks, backplanes and power modules across the Siemens SIMATIC and ABB AC500 and Advant platforms. Whole-system parts are stocked alongside individual CPUs so a controller can be rebuilt rather than replaced. Discontinued generations, including SIMATIC S5, remain available for plants running original hardware.Power Supplies(1513)Regulated DIN-rail power supplies, redundancy and buffer modules for control panels, including the Siemens SITOP range and ABB equivalents. Sizing here is usually driven by the existing panel layout and load, so both current and superseded models are stocked. Units are load-tested before dispatch and carry a 1-year warranty.
