New to PLCs - Step 5
New to PLCs - Step 5
(OP)
Hello all,
I'm very new to PLCs and I'm basically teaching myself a bit now I've started my first job since graduating.
I'm using Step 5 on a S5-100U PLC programme and have come across some formatting in the code that I haven't seen before and can't find in the manual I'm using.
Could someone tell me what the circled code means in the attached picture? Are they just comments?
The programme is written by a German company, in case that helps! Many thanks

In fact, why is it that some of these networks can't be displayed as ladder? Is it just because of the jumps in the code that can't be translated?
But anyway, my first question still applies - it'll be great to know how to handle that code at the bottom. Thanks!

Somewhere in the code you should find that block definition, including all commands used for this particular block
