Hello.We are using S7-300 Cpu.Sometimes give an error.OB86 and OB122 blocks called.OB86 Block ;
L #OB86_FLT_ID
T DB1.DBB 14
L #OB86_EV_CLASS
T DB1.DBB 15
L LB 11
T DB1.DBB 16
When I looked to DB1.
DB1.DBB14 : Byte: B#16#C4
DB1.DBB15 : Byte: B#16#38
DB1.DBB16 : Byte: B#16#5
And in OB122 Block:
L #OB122_MEM_AREA
T DB3.DBW 14
L #OB122_MEM_ADDR
T DB3.DBW 16
When I looked to DB3.
DB3.DBW14 : Int:16
DB3.DBW16 : Int: 4
is showing.And we make plc stop/run.Maschine is run and operating again.
According to these values can we fix problem.That is which module is defect?
Thanks in advance.
