Dear All, I have a S7-300 program in which there are many contacts used as inputs and outputs like DB2.DBX0.1, DB2.DBX1.2, DB2.DBX2.3 etc. I don't know about these types of contacts, please help that whats are these. In program these contacts are used in many outputs, Why memory not used (M). Please see attachements of DB2, FC2. In FC2, in many networks these contacys are used. AttachmentFC2.pdf (264 Downloads) |

Hello, DB2.dbx0.1 means Bit 0.1 in DB 2, Your DB2 is a DB full off those bitis, the problem is you see only stat 1, stat 2, that's because it's probably a upload. Normaly you see names there. Why not M bits ? May be to save M memory or to exchange bits with a HMI easy. And
Whow, you must be over 100 years old :-) Regards, Marcjan AttachmentDB example.pdf (335 Downloads) |
