teh said:What is diferent between S5 C DB and S7 OPN DB?
I found that when i convert the program from s5 to s7
the function of OPN DB can only execute in that
particular network and cannot call the other data for following
network.
Jeebs said:It's the same thing, no difference. But you should be aware that if you do:
OPN DB1
L DBW 10
L DB2.DBW10
At the end of that statement DB2 will be open and not DB1. Any subsequent L DBW/DBD/DBB will load data from DB2.
PeterW said:What DB is "DIGITAL INPUT", as that is the DB that you are using in Network 3.
L D[AR2 said:When you post code, please use absolute addressing - no one has to then guess at what is behind the symbol. Can you post the original step 5 for network 3 for example ?
