Hello everyone! I'm exploring the possibility of monitoring connection status within my application, similar to tracking device status. While we usually implement our own watchdog mechanism, I'm curious to know if there's a standard approach available. Any insights would be greatly appreciated. Thank you!
You can check the NDR (Non-Delivery Report), along with the error outputs, to manage communication counters effectively. One of these bits will be set to true for each PLC scan following the transmission of a message.
Certainly! Here's a refined version of the original text: "Hello! We can definitely accommodate that request; however, I was hoping for a specific system function, such as a block feature."
I prefer to transmit a clock value, as it serves as an indicator; if there’s no change in the clock value, it signals that your communication may have been interrupted or lost.
Absolutely, we engage in a similar process that is quite straightforward. However, my colleague is convinced he encountered a standard block during a seminar presentation.
It is essential for PUT and GET operations to consistently include a heartbeat signal or a rolling counter, even when the partner PLC is in a stop state. While it's not catastrophic if these elements are absent, implementing them is considered best practice for ensuring reliability and communication integrity in industrial automation systems.
