Any device that speaks Modbus TCP or RTU can feed TagFirst. Map holding, input and output registers, then configure live viewing, logging and traceability — no code required.
Modbus is the universal fallback of the industrial world — if a controller, meter, drive or sensor doesn't have a native driver, it usually speaks Modbus. TagFirst includes a generic Modbus connector so you can bring those devices into a configurable SCADA layer without custom code.
TagFirst-Solo (Phase 1) speaks generic Modbus over both transports, with access to the standard register areas.
| Transport | Register areas | Use |
|---|---|---|
| Modbus TCP | Holding, Input, Output | Ethernet devices & gateways |
| Modbus RTU | Holding, Input, Output | Serial RS-485 / RS-232 devices |
Point TagFirst at the device — an IP address and port for TCP, or serial settings for RTU — then map the holding, input and output registers you want to read and write. Assign data types (INT, DINT, REAL, BOOL, STRING), upload register lists from Excel, and let TagFirst auto-calculate addresses and expand bit-packed words.
Configure logging to Microsoft SQL Server with auto-created tables, add validation and local duplicate checks, and connect previous-station databases for multi-operation traceability. Drive label printers or marking machines over Serial, TCP or USB, with optional scan-after-print verification.
