Yes. Example: control upgrades for the booster gas compressor and gas lift compressor on PVEP's DMDP-A platform, Blocks 01 & 02 (2023–2024), from FAT in Ho Chi Minh City to offshore commissioning.

Yes: safety instrumented systems for SIL 2 and SIL 3 functions on AADvance and Trusted, including ESD and Fire & Gas, and safety PLC applications on GuardLogix.

Both. TDL delivers complete control and automation packages: engineering, supply of the control equipment, panel fabrication at its Ho Chi Minh City workshop, PLC and SCADA programming, FAT, site commissioning and training.

Yes. TDL delivers the control system package for EPC contractors, for example the natural gas compressor and tripper car upgrades at Phu My Fertilizer Plant and the biomass processing control system at Nestlé Tri An.

Yes. TDL has maintained P&G Vietnam's Dong An plant since 2012 and URC Vietnam's coffee and creamer factory since 2014 under yearly contracts: scheduled visits, backups, on-call support and changes on demand.

Yes. PanelView Plus 6, 1000 and 1250 terminals are replaced with PanelView Plus 7 and the application converted, often in the existing panel cut-out.

Yes. TDL maintains and extends the facility and power monitoring systems at Samsung's SEHC complex in Ho Chi Minh City on AVEVA System Platform, including HVAC and air compressor integration.

Email sales@tdl-ia.com.vn with your scope, or call the hotline for urgent breakdowns (phone, WhatsApp, Zalo).

Often yes. Depending on the plant, the existing I/O can stay for a first phase and be connected to the new ControlLogix controller, or be replaced with new I/O in the same panel. TDL compares both options during the survey.

The program is converted and tested before the stop, so site work is limited to installation, checks and start-up. The length depends on the I/O count and wiring; past migrations were done within planned shutdowns, including an 8-day platform shutdown.

Yes. RSView32, Citect and PanelView applications are migrated to FactoryTalk View SE/ME and PanelView Plus 7 together with the controller.

Scheduled preventive maintenance visits, backups compared with the previous baseline, health checks, on-call support and changes on demand, agreed for each plant.

Allen-Bradley controllers, HMIs and drives, FactoryTalk and AVEVA SCADA, servers and workstations, and drives of other makes, as at URC Vietnam.

Response times and the yearly support allowance are agreed in each contract.

Yes. Older Wonderware applications are upgraded to current AVEVA versions, often together with PLC upgrades, as at Nestlé's Tri An and Dong Nai plants.

Yes. Changes are made inside the customer's own templates and object standards, for example P&G's OPERA standard on System Platform.

Citect SCADA is now AVEVA Plant SCADA. A Citect system can be upgraded within AVEVA Plant SCADA or migrated to another platform; TDL migrated Citect to FactoryTalk View SE at Pha Lai II.

Per server. One Ignition licence covers unlimited clients, tags and projects; modules are bought as needed.

Yes. Ignition has built-in drivers for ControlLogix and CompactLogix, so it can run alongside an existing FactoryTalk or AVEVA system.

When a plant has standardised on that platform or on PlantPAx, or needs features tied to it. TDL compares the options against the plant's standards, licence budget and support needs.

Not necessarily. N3uron is usually added alongside the existing SCADA to collect and forward data; it also has Web Vision for simple web HMI.

To MQTT brokers including Sparkplug B, to databases and historians, to cloud platforms and to OPC UA clients.

Yes. N3uron runs on Windows, Linux and ARM-based edge devices.

For many older PanelView Plus terminals, adapter kits let the PanelView Plus 7 fit the existing cut-out, as on the VinWonders roller coaster console. TDL checks the model and cut-out during the survey.

No. Existing applications are converted and then checked screen by screen; only screens or objects that do not convert are redrawn.

Usually not. The new terminal reads the same controller tags; only the communication path changes when an old DH+, DH-485 or ControlNet link is replaced with EtherNet/IP.

Not always. Newer ControlLogix and CompactLogix controllers can stay and receive EtherNet/IP modules; older controllers are often upgraded in the same project, as on the Crown Da Nang body maker.

Yes. Lines or units can be moved one at a time while the remaining sections keep running, as on the P&G Dong An packing lines.

Managed Stratix switches, segmented by line or unit, with DLR rings or redundant networks where the process needs them.

Yes. BACnet/IP and Modbus devices are brought in through gateways and KEPServerEX, as for the AHU, OAC and air compressor integration at SEHC.

The SEHC FMCS and PMS run on AVEVA System Platform. TDL can also build facility monitoring on FactoryTalk, Ignition or N3uron where that fits the plant's standards.

Yes. Facility systems can be covered by a yearly maintenance contract with scheduled preventive maintenance of servers, workstations and PLCs, backups and on-call support.

Yes. In production and office buildings on industrial sites, AHUs, OACs and exhaust fans are controlled on CompactLogix or ControlLogix and supervised from the FMCS SCADA, with packaged equipment connected over BACnet/IP or Modbus, as at SEHC.

A list of the installed control hardware and software with its lifecycle status, current backups, a list of critical spares and a prioritised upgrade plan.

No. On PVEP's DMDP-A platform only discontinued and end-of-life parts were replaced; modules still in active lifecycle were kept.

Yes. Send the part numbers and quantities through the request form and TDL quotes Allen-Bradley spare parts for running systems and breakdowns.

Yes. At SEHC an air compressor, AHUs, OAC units and sensors were added to the running FMCS SCADA, with historian and report entries.

Yes. Changes at P&G Dong An are made to P&G's OPERA standard on System Platform.

Yes. Wonderware System Platform is now AVEVA System Platform; AVEVA is owned by Schneider Electric.

Yes. At Nestlé Dong Nai and Nestlé Tri An the Wonderware applications were updated and reconfigured for the new PLCs.

Yes. Wonderware InTouch is now AVEVA InTouch HMI; the Wonderware products are part of AVEVA.

Yes. At Phu My Fertilizer Plant the GE Fanuc control system of a natural gas compressor was migrated to redundant ControlLogix 5580 with 1715 redundant I/O, for the EPC contractor.

Not always. On PVEP's DMDP-A platform, discontinued modules were replaced and modules still in active lifecycle were kept, to keep the shutdown short.

Yes. On the Phu My natural gas compressor, the Bently Nevada 3500 rack, the anti-surge controllers and the Modbus links to the plant DCS stayed integrated with the new ControlLogix system.

Yes. At P&G Dong An the AssetCentre server was connected to the existing PLCs as well as a new PLC from HDL making.

Yes. Under yearly maintenance contracts, programs and drive parameters are uploaded on each visit and compared with the previous baseline, as at URC Vietnam.

At P&G Dong An, AssetCentre runs on a Windows Server virtual machine with Microsoft SQL Server for its database.

Usually not. At Yakult Vietnam the existing Mitsubishi PLC stays in control and its data is read over Modbus; at Thi Vai the PLC-5 controllers were kept and connected through DH+ to EtherNet/IP converters.

FactoryTalk View SE, FactoryTalk Optix and AVEVA System Platform in the projects on this page; Ignition and N3uron are also options.

Yes. At SEHC the air compressor and AHU data were added to the historian and the automated reports.

OEE = availability × performance × quality. Availability is running time over planned production time, performance is actual output over the output at ideal speed, and quality is good units over total units.

Only where the data is missing. If the PLC already holds machine states, counts and alarm words, they are read as they are; if not, they are added with small program changes and tested on the line.

Usually the bottleneck line or a line with frequent changeovers, where the lost time is largest. Further lines are added once the first one is running.

Yes. Production counts and stop data can be sent to MES or ERP through database or web-service interfaces; on Ignition, Sepasoft's Business Connector and Web Services modules are options.

Yes. Sepasoft modules are installed on an Ignition gateway together with Sepasoft's Production component and use Ignition's Vision or Perspective screens; Batch Procedure runs on Perspective.

OEE Downtime, Track and Trace, SPC and Settings and Changeover are licensed per site, without a limit on lines, machines or users at that site. Batch Procedure and the connector modules are licensed per server.

Yes. Ignition reads ControlLogix and CompactLogix tags over EtherNet/IP, so machine states, counts and alarms come from the existing PLCs, with program changes only where data is missing.

No. A common first step is OEE Downtime on one line; Track and Trace, Settings and Changeover or SPC are added when the plant needs them.

Yes. TDL quotes the control system scope that an EPC contractor or main bidder needs inside a larger package, from engineering and programming to panels, testing and commissioning.

Yes. For example, the control panels for the Intel Vietnam SWTP project were built with Rittal enclosures to Intel's standards.

Yes. On several fertilizer and food plant projects the EPC contractor supplied the main hardware and automation software, and TDL delivered the engineering, programming and site work.
