Hi,
I am relative new to plc, and was wondering in anyone could explain the data block adressing below?
If you use #IndexDB = 50 and #IndexByte = 226.
L #IndexDB //Load first DB number in data area
T #DB_Source
L 200 //The start byte number in Workspace DB
T #Word_Dest
L 20
T #DB_Dest
L 10 //10 DB is to be copied
MrkA: T #Loop_Counter
L #IndexByte
T #Source_Word
L #Source_Word
SLD 3
T #Source_Word
L #Word_Dest
T #Dest_Word
L #Dest_Word
SLD 3
T #Dest_Word
L 2
next: T #Loop_Counter1
OPN DB[#DB_Source]
L DBW[#Source_Word]
OPN DB[#DB_Dest]
T DBW[#Dest_Word]
L #Source_Word
L P#2.0
+D
T #Source_Word
L #Dest_Word
L P#2.0
+D
T #Dest_Word
L #Loop_Counter1
LOOP next
L #DB_Source //Increment Active DB number by one
L 1
+I
T #DB_Source
L #Word_Dest //Increment Active Word number by Length
L 2 //(2 x Length because off Byte number)
+I
L 2
+I
T #Word_Dest
L #Loop_Counter
LOOP MrkA //Loop 10 times for 10 DB´s
Thank you.
