Five controller platforms, four SCADA systems, five drive lines
A plant rarely runs one brand. The utilities are Siemens, a packaging line is Omron, and the chiller skid arrived with whatever its OEM used. Filter by what you have installed.
Filter by controller
Allen Bradley
Rockwell AutomationThe most common installed base in semiconductor and pharma utilities, and the most common source of an obsolescence problem — PLC-5 and SLC-500 lines still running plant that has to keep running.

Siemens
SIMATICWhere most migrations land. The S7-300/400 to S7-1500 path is the single most requested upgrade DNM handles, and it is rarely a like-for-like conversion.

SCADA and HMI
Supervisory platforms
Including the migrations. Every one of these has a legacy version still running plant somewhere, and none of those migrations is an import.
FactoryTalk View / RSView
Rockwell Automation- FactoryTalk View SE
- FactoryTalk View ME
- RSView32
- Site edition distributed servers
- Alarm and event historian
- Trend and datalog configuration
- VBA display scripting
Pairs natively with the Logix family. RSView32 migrations are common and are never automatic — the display set has to be rebuilt.
WinCC
Siemens- WinCC Professional
- WinCC Advanced
- WinCC Comfort
- WinCC Flexible (legacy)
- Tag logging and archiving
- Alarm logging with acknowledgement paths
- VBS and C scripting
- Report generation
The WinCC Flexible to TIA Portal path is a rewrite, not an import. Budget for it explicitly.
Wonderware / AVEVA
AVEVA- InTouch
- System Platform
- Historian
- Galaxy object model
- ArchestrA graphics
- Historian tag archiving
- Multi-node deployment
The right choice when the plant needs one object model across several machines from different OEMs.
Citect SCADA
AVEVA / Schneider Electric- Citect SCADA
- Vijeo Citect
- AVEVA Plant SCADA
- Cicode and CtAPI
- Redundant server pairs
- Alarm and trend servers
- Native Modbus and OPC drivers
Heavily used in water and wastewater. Redundancy configuration is where most inherited Citect systems are found to be wrong.
Drives
Variable frequency and servo drives
Usually the first thing replaced in a phased retrofit, because it is the lowest-risk window and the highest-obsolescence risk.
- SINAMICS / SIMOTICSSiemens
SINAMICS G120 · SINAMICS V20 · SIMOTICS servo drives
Servo and general-purpose, commissioned over PROFINET from the same TIA project as the PLC.
- PowerFlexAllen Bradley
PowerFlex 525 · PowerFlex 753 · PowerFlex 755
Add-on profiles in Studio 5000 make drive parameters part of the controller project, which matters for backup and recovery.
- AltivarSchneider Electric
Altivar ATV320 · Altivar ATV630 · Altivar ATV930
Process drives on pumps and fans; ATV630 is the common choice on RO and wastewater duty.
- VLT / VACONDanfoss
VLT AQUA · VLT HVAC · VACON 100
Dominant on HVAC and water duty, with pump-specific firmware functions worth using rather than reimplementing in the PLC.
- FRENICFuji Electric
FRENIC-Ace · FRENIC-Mega · FRENIC-Eco
Frequently found on imported machinery. Direct replacement is usually cheaper than adapting the machine to another brand.
Networking
Protocols and fieldbus
Bringing a third-party device onto the network is most of the integration work on any mixed-vendor plant.
- EtherNet/IP
- PROFINET
- PROFIBUS
- Modbus TCP
- Modbus RTU
- CANbus
- ControlNet
- DeviceNet
- OPC UA
- OPC DA
Standards
How the work is structured
- IEC 61131-3 — PLC programming languages
- The programming standard the brief names. Ladder, function block, structured text and SFC, applied deliberately rather than whichever the last engineer preferred.
- IEC 62443 — Industrial cybersecurity
- Segmentation, remote-access discipline and account handling on OT networks. DNM works to its principles; it is not a certification claim.

Tell us what you have installed
Controller brand, SCADA platform, roughly how many I/O. That is usually enough for us to say whether the job is straightforward or not.
