Ping & TCP

/tools/ping is two independent network reachability tools on one page. Both run from the Edge Server, not your browser — which is exactly what you need when the question is "can my Edge Server reach this device?"

ICMP Ping

Field	Notes
Host	Hostname or IP.
Count	1, 2, 4, 6, 8, or 10 echo requests.

Click Start to stream results live. The results table shows sequence number, status (Reply or Failed), RTT in milliseconds, the resolved address, and the timestamp of each probe. A summary row aggregates Sent, Received, Loss %, and Min / Max / Avg RTT. Stop cancels an in-flight ping.

TCP Connectivity

Field	Notes
Host	Hostname or IP.
Port	TCP port (1–65535).
Timeout	Seconds to wait (default 5).

Test opens a single TCP connection and reports Open or Closed, the resolved address, duration in ms, and the underlying error if the connection failed. Use this to verify that, for example, Modbus port 502 is reachable on a PLC before you wire up a client in the cloud.
