Hi, How do you supply the card? Is that possible that 24V is not on constantly on the supply? See the SIMATIC S7-300 S7-300 Module data manual under chapter "3.23 Digital output module SM 322; DO 16 x DC 24 V/ 0.5 A; (6ES7322-1BH01-0AA0)" . Where you can read: "When using a mechanical contact to switch on the 24-V power supply to SM 322;
DO 16 x DC 24 V/0.5 A, its outputs will carry "1" signal for the duration of ca. 50 µs, due to
the circuit structure." |
- What you read here, please check with manuals and your requirements. |
