The VM memory of the LOGO! is not retentive. The HMI transmits the signals to the VM memory only once, namely at the time of acceptance of the value. If the LOGO! restart, the VM memory is empty. With the digital values you work best with pulse signals (like a button, not like switches) and in the LOGO! with latchuing relay or pulse relay. AttachmentForum.zip (121 Downloads) |
