Alright, so I have this Delta VFD drive, and to give it commands over modbus, it wants me to send it RTU (or ascii) strings. The strings are setup as follows: START - A silent interval of more than 10ms. Address - Comm. Address: 8-bit address. Function - Command code: 8-bit command. DATA (n-1) to DATA 0: Contents of data. CRC CHK Low - CRC Check sum: 16 bit check CRC CHK High - sum consists of 2 8-bit chars. END - A silent interval of more than 10 ms. I 've tried using the MWX and MRX blocks in the dl06, but they will only read the first 30 or so addresses in the drive. I need to access the higher parameters. So, I guess I'm down to sending it individual blocks of data to get what I need. My question is how would I go about sending this data over modbus w/o using the MWX/MRX command? Thanks
