Addelichtman Posted April 8, 2019 Report Share Posted April 8, 2019 Hello I am trying to send an explicit message to a Unistream PLC as seen above. This picture is made from a third party EIP scanner and works as is. The message unlocks a device I am controlling. Note that the Command is NOT 0x10 but a special command 0x45 I also have to set request data 0xCD. So the Adapter's documentation of the message is: Service Code: 0x45 Class: 0x67 Instance: 0x89 Attribute: 0xAB Data: 0xCD The ladder component I use is 'EIP General Explicit Message' as seen below: I send the required 0xCD data via the debugger. As you see I get an error -4 which is documented as 'ENIP_WRONG_OFFSET' . I tried several buffer sizes and offsets but none of them gives a correct result. Could someone please help me on how to tackle this problem? Thanks! Ad Quote Link to comment Share on other sites More sharing options...
