go-mcprotocol is a library for PLC (Programmable Logic Controller) access
Work In Progress
You can read plc register bellow codes.
client, _ := mcp.New3EClient(opts.Host, opts.Port, mcp.NewLocalStation())
read, _ := client.Read("D", 100, 3)
registerBinary, _ := mcp.NewParser().Do(read)
fmt.Println(string(registerBinary.Payload))
if err := client.HealthCheck(); err != nil {
log.Fatalf("failed health check for plc: %v", err)
}
Format is CSV. Items are timestamp and Base64 encoded MC Protocol response.

Collect the register valuesof PLC by MC Protocol(MELSEC Communication Protocol). This tools is gather plc register data and dump local files.
$ plcmirror -H <Your PLC Host> -P <Your PLC Port> --device D --offset 100 --num 10 --dir /var/log/plcmirror
> plcmirror -help
Usage:
plcmirror [OPTIONS]
Application Options:
/H, /host: PLC hostname
/P, /port: Melsec communication protocol port number
/D, /device: Register name like D that is mirror target
/O, /offset: PLC register offset addr that is mirror target
/N, /num: number of device points
/dir: file output path (default: .)
