abbot Posts: 4 Rating: (0)	I use cpu 312 which have two cp 341 . The first address is 256 ( put dongle modbus master ),the second (put dongle modbus slav ). I program to communicate each other between two cp 341 but not wok and show error 830. I did all instruction manual and I found the same error 830 again . What should I do? I will attach you the program and could u check db 44(source data) that is it sending the right message? Attachment Modbus master test.zip (157 Downloads)

Kaulquappe Posts: 3093 Rating: (324)	Hello Abbot, BCD conversion error occurs when converting e.g. integer to BCD or vice versa. Do you call any conversion blocks in your program? Ifyes, just evaluate the outputs of the blocks. Regards, Kaulquappe
