Couple of Siemans questions

[just the cowboy]

I am converting an old Siemans program to AD and I have a couple of questions.

Looking at the old printout I guess

NETZWERK # is equal to a rung #?

In the corner it says LAE= xxx, I assume this is file number.
The printout, if it is file number is not consective so I am writing it in the order printed. I assume this is correct

On the set/reset instruction some time the S is on top and sometimes the R is on top in the insrtuction does this matter or is it a printout thing, I am writing the program in the order it shows in the instruction.

I am sure I will have more questions it is the first Siemans I am rewriting.
Thanks
Harvey

Yes, Networks is the same as rung. Siemens (Step 7 and TIA Portal, at least) do not have a network 0.

The S in the coil is SET (or latch). The R is Reset (or unlatch). Don't know anything about LAE.

LAE numbers are not relevent for conversion. I believe it is showing the starting address of the printed page in the PLC memory. I'm sure you have the printoutof an S5 PLC.

In simatic step 7 v5.5 set on bottom means set priority. The other way round with reset on bottom means reset priority.

Reset_Set Flip Flop is reset when the signal state at input R is 1 and the signal state at input S is 0. If input R is 0 and input S is 1, the flip flop is set. If the RLO at both inputs is 1, the flip flop is set.


Set_Reset Flip Flop is set when the signal state at input S is 1 and the signal state at input R is 0. If input S is 0 and input R is 1, the flip flop is reset. If the RLO at both inputs is 1 the flip flop is reset.

Thanks

With the LAE I just thought it odd that the numbers went up then back down, logic wise the flow looks correct.
Next to the rung number it does have address starting numbers. Yes it is a old S5

With the flip-flop that was what I thought but just wanted to make sure.
Thanks again

LAE = LAENGE = LENGTH. If I remember correctly, this is the overall length of the actual program block. In words or bytes, dependant of CPU type.
