I want to check if FTLinx is running on a PC. @Ken Is this possible using the method mentioned. If so, can you give some more details on reading the identity object please?You almost certainly don't want a PING command. PING doesn't tell you anything about the status or type of device on the network.
You probably want a watchdog function. I usually do this by having the HMI computer write the /Seconds value from the PC clock to the PLC. As long as the tag it is writing to is changing, I know that the PC is connected and that the HMI program is executing.
Another method I have used with PanelView and computers running RSLinx is to send a MSG instruction with the CIP object to read part of the Identity Object. When you get a reply to such a message, you know that the computer is connected and that RSLinx is running.
Ping will merely tell you that the IP address you pinged is connected to the network. It may even be another PLC, IO, HMI, Server, you name it... but it won't be Linx.I want to check if FTLinx is running on a PC.
I am aware of this. The only reason I replied in this thread was because I wanted more information on Ken’s post regarding the identity object.Ping will merely tell you that the IP address you pinged is connected to the network.
