Mar 30, 2021 · On the other hand, a timeout value of 1 second might be more appropriate when supervising slow PLC’s through a gateway across a serial link, where the normal scan sequence completed in 300 msec. Applications which are not time critical can often leave timeout values to the normal TCP/IP defaults, which will report communication failure after

Mar 06, 2017 · So how can you set up Configuration Control at the device level? Let's build a quick example. While we could use an S7-1200, S7-1500, or ET200SP I/O remote rack, I'm going to use an ET200SP Controller (S7-1510 1-PN) as I have one sitting on my desk. Additionally, I have one (1) DI 8x24VDC ST and one (1) DQ 8x24VDC/0.5A ST module.
