problem with logo and hmi ktp400

PrzemekGra Posts: 14 Rating: (0)	Hello It is an exchange of data between the logo and KTP400. Does anyone know what I'm doing wrong? I tested a program consisting of three blocks. After entering the value "40" in the panel - variable VW2 and sending it to the logo, I want to read it back in the panel - variable VW130. The problem is that I get back the value 65078. Thank you in advance! Attachment nn.jpg (744 Downloads)

Control the settings in the in the HMI tags. The values from the LOGO! must have the data format "Int" In you LOGO! program you read with a NAI the address VW2 and then connect you the NAI to the analog amplifier B014. In B014 you set a offset of -498 and connect the output to a NAQ with the address VW130. In this case has the VW130 the value of -498. I think you have select in the HMI the data format "Word".
