cmarcus Posted December 8, 2010 Report Share Posted December 8, 2010 Hi guys, I'm trying to have my V130 PLC use COM2 to send data to another device. The device is especting byte array message structure as follows: FF 05 01 01 00 00 00 A6. Unfortunately, I can not for the life of me seem to send the checksum properly: FF 00 01 01 00 00 41 36. The 41 and 36 appear to be the ASCII values of the proper check sum. Is there any way to send the checksum as a byte? Quote Link to comment Share on other sites More sharing options...
Ofir Posted December 9, 2010 Report Share Posted December 9, 2010 Hi, Do you need to send the checksum as binary? When you configure the check sum in FB Protocol Send try to change the format (The first field combo box) to binary. Quote Link to comment Share on other sites More sharing options...
