Request on bootup / Answer bootup request #5

Open arsi-apli opened 3 months ago

arsi-apli commented 3 months ago

Your project helped me in programming my Java version, so I will add something new... In newer versions of CoDeSys there is a new setting Request on bootup/ Answer bootup request. When Answer bootup request is activated, the current value of the variable(s) can be requested through this. The data is in CTelegram format, but there are a few changes.

CTelegram.ID = 6
CTelegram.Index = Cob-ID
CTelegram.SubIndex = 0 / Variable index If "Pack-Variables" is disabled
CTelegram.items = Number of Variables / 1 If "Pack-Variables" is disabled
CTelegram.Length = 0x14
CTelegram.Counter = always 0
CTelegram.Flags = always 0
CTelegram.Checksum  = always 0
CTelegram.Data =  byte[0]

Example:

                                   ID             Index      SubIndex     items       Length     Counter   Flags  CRC
                         vvvvvvvvvvvvvvvvvvvvv  vvvvvvvvvv  vvvvvvvvvv  vvvvvvvvvv  vvvvvvvvvv  vvvvvvvvvv  vvvv  vvvv
0x00, 0x2d, 0x53, 0x33, 0x06, 0x00, 0x00, 0x00, 0x0a, 0x00, 0x02, 0x00, 0x01, 0x00, 0x14, 0x00, 0x00, 0x00, 0x00, 0x00
