# Talk to the machines you already have

> Native drivers for the controllers found on most shop floors, available in all three products. Browsable protocols open as a tree, related addresses are read together, and every value carries a quality code.

### Modbus TCP / RTU

`modbus_tcp · modbus_rtu_tcp · modbus_rtu` — Holding and input registers, coils and discrete inputs, register bits, selectable word order for 32/64-bit values, RTU over TCP and serial.

### Siemens S7

`s7` — S7-200, S7-300, S7-400, S7-1200, S7-1500 and LOGO!: data blocks, markers, inputs, outputs and S7 strings, read in optimised multi-item requests.

### Mitsubishi MC 3E / 4E

`mc3e · mc4e (ASCII / binary)` — Q, L, FX5 and iQ-R: data, file and link registers, bit devices, timers and counters, read in blocks.

### Omron FINS

`fins_udp · fins_tcp` — CS, CJ, CP, NJ and NX series: DM, CIO, work, holding, auxiliary, timer, counter and EM areas over UDP or TCP.

### Allen-Bradley EtherNet/IP

`eip_logix` — ControlLogix, CompactLogix, GuardLogix and Micro800 with symbolic tag access: controller and program tags, arrays, UDT members and strings, with tag browsing.

### FANUC FOCAS

`focas` — CNC status, axis positions, spindle speed and load, feed, alarms, macro variables, parameters, diagnosis, PMC areas and program numbers over Ethernet.

### CODESYS NVL

`codesys_nvl` — CODESYS V2/V3 network variable lists over UDP: receive and send lists, arrays and strings, multicast and a watchdog for stale data.

### OPC UA client

`opcua_client` — Polling or subscriptions, address-space browsing, None / Sign / SignAndEncrypt with automatic client certificate and trust management.

### OPC DA client

`opcda_client · Windows` — OPC DA servers on the same PC or over DCOM, with server discovery, cache or device reads and browsing.

### Haas CNC

`haas_q` — Machine data collection: status, program, parts, cycle times, tool changes, spindle and positions, macro variables.

### MTConnect

`mtconnect` — Samples, events and conditions from any MTConnect agent, with quality and browsing of all data items.

### Simulator and virtual variables

`sim · internal` — Signal generators for tests and demos; virtual variables for operator entries such as work orders and planned stops.

## Faster engineering

- **Browse instead of typing:** OPC UA, OPC DA, Logix, NVL, Haas and MTConnect open as a tree; select the values and add them in bulk.
- **Or let AI do it:** An AI assistant knows the address syntax of every driver and can create and test devices and tags over MCP.
- **CSV import and export:** Prepare hundreds of tags in a spreadsheet and import them; export for documentation or another site.
- **Quality on every value:** Good, uncertain, stale or bad: screens, history, alarms and OPC UA clients see the same quality code.
