Sorry, it should be "Siemens TIA Portal" . No other software will make me to swear like a soldier

I swear like a "sailor" [much worse than a soldier] anytime I have to use that ghastly mess of a TIA Portal.

Program complexity grows until it exceeds the capability of the programmer to maintain it. I used to swear like a sailor when using TIA Portal V11 and V12. With V13 is it only like a soldier. Never comment a program. If it was hard to write, it should be hard to read.

Ok -- I bit the bullet and edited a new edition finally [2016 Edition].  It is with the proof readers now and hopefully will be available in the downloads section in a week or so.  thanks gleblanc, RussB and JordanCClark for your assist.

It is out and in the downloads sections.  The "official 2016 - 10 year anniversary edition" of the PLC Laws.  Enjoy and chuckle.

IF YOU ONLY FOCUS ON THE PROBLEM

 

YOU WILL NEVER SEE THE SOLUTION

Yes, I know... I'm the woman who has to find & keep copies of the manual that the men never read. <g, d & r!>

I read manuals until I know them.

I've always prepared myself everyday like this: On any given service call, expect a punch list of issues from the past 20 years.

(PLC Law 7.2) Just because a Cable fits(or someone makes it fit) the port, doesn't mean it is the right cable for the application.  ie.  DH-485 in RJ-45 ethernet port.  Mitsubishi FX-series serial 232 in AB DH+ port.  (Trust me, it happens)

...or the other way 'round: plug in Ethernet cable to DH-485 port.

 

RS-232 cable to Profibus port...

When that didn't work, they tried adding a null modem adapter, which they forgot to remove from the front of the processor...

The processor is down low in the cabinet and not easy to see, so the next person to connect (yours truly...) didn't see the null modem adapter and plugged in the PC adapter, which instantly fried the PC adapter. The $500+ PC adapter became a paper weight.

Sigh...

Note sure this one has been covered, if so I apologize.

Dear Service Tech: If you add a wire to the control panel in an poor attempt to overcome what you think is a faulty relay, sensor, fuse holder...yes, you must put a label on it, at both ends.  You must red line and update the drawing package.  That way when I get called, I can actually fix the problem correctly.  And while you're at it, could you please put all the wiring back in the wire duct and reattach the cover?
