Hello, If your HW configuration and wiring is ok then you read current the same way as voltage. I normally use Load command: [code]L PIWxxx[/code] And scaling is simple. If your input is configured as 4..20mA then you read value 0..27648 respectively. Look at this manual chapter 5 to have bigger knowledge about how analog values are represented in S7-300 PLC. |
Best regards, |
