Hello, look to this Topic what shows similar problem: S7-300 with Et200SP CM PtP As my sugestions there show correct Pointer notation, this Topic also show correct use of comm block FB614 (RECV block). Check and adapt your prj to this one from Topic, it can be solution. Your Pointer need to be set correctly with max available BYTEs in Array defined, f.ex. P#DB2.DBX2.0 BYTE 20 what means you have send buffer defined in DB2 from DBB2 offset and is long 20 Bytes. With LEN of send you can define any LEN you want send but only max you have defined in DB and also with Pointer notation as I show. Simply you need set for both blocks correct Pointer to buffer as is defined in your DBs. |
