#159236 - Frame error Responding to: ???'s previous message |
Deppending on your master program, frame error could mean that CRC is not correct.
In http://www.modbus.org/docs/Modb..._V1_02.pdf you will find a good example of a fast C procedure to calculate CRC. Oh, you need 512 bytes of code, for tables. Daniel BTW, how can we post "bracket i bracket" without changing to italics? |
