SCADA & Data Logging for Delta PLCs

Connect TagFirst to your Delta DVP or AS series PLC, map your registers, and get live viewing, data logging and traceability — configured, not coded.

Delta PLCs are everywhere on Indian shop floors, and they're a first-class target in TagFirst. Configure a complete SCADA layer — live screens, logging and traceability — for your Delta machine without hiring a developer.

Supported Delta series

TagFirst-Solo (Phase 1) connects to Delta's common families using D register addressing over TCP/IP or serial.

AS SeriesD registerTCP/IP, Serial

How it connects

Enter the Delta PLC's IP address or serial port in the configurator, then map the data registers you want. TagFirst handles INT, DINT, REAL, BOOL and STRING types, auto-calculates addresses, and accepts tag lists uploaded from Excel. Bit-packed status words are auto-expanded with SPARE fill so each bit becomes a usable tag.

Designed for the floor. The runtime is offline-first and the PLC stays in control — a one-second heartbeat lets the PLC detect and alarm if the PC application ever halts.

Logging and traceability

Map your tags, then configure logging to Microsoft SQL Server with auto-created tables. Layer on validation (prefix, exact, suffix, within, range, min/max), local duplicate checks with rework logic, and previous-station verification for multi-operation lines. Add label printing or dot-mark commands where you need part marking.

FAQ

Questions about this.

Which Delta PLCs does TagFirst support?+
TagFirst-Solo supports the Delta DVP and AS series using D register addressing over TCP/IP or serial. If you use another Delta family, contact us about adding it.
Do I need Delta's programming software to connect TagFirst?+
No. TagFirst talks to the PLC over its network or serial interface. You just need the connection details and the D register addresses you want to read or write.
Can I log Delta PLC data and scanned serial numbers together?+
Yes. TagFirst maps PLC tags and scanned/keyed data into the same SQL Server record, alongside system fields like timestamp, shift and line.
Is the Delta configuration portable to another machine?+
Each package is built for one machine and locked to its dongle, but you can reuse a configuration as a starting point and re-generate a new versioned package for a similar machine.
