DL305 - DL330/340 CPUs Frequently Asked Questions
| Question | I can't edit control relays from data view with a D3-330 or D3-340. What am I doing wrong? |
| Answer | You're not doing anything wrong. The D3-330 and D3-340 use Direct Net protocol only. You can only write at a byte level with DirectNet. You must edit the entire R register containing the C bit you wish to change. You should examine the R register containing the C bit and edit the entire register with the BCD value that would reflect the bit pattern you're wanting. The D3-350 also uses DirectNet and you can do the same thing editing V-memory. Better yet, with the D3-350 you can switch to K-Sequence protocol and do bit level reads and writes. |
