Siemens Part Numbers

Dear Sirs,
I have what are supposed to be three identical machines, with interchangeable
parts . . Just the three machines get bigger.

They have Siemens PLC's in them, and they all have ET200S I/O blocks
in them.

The number one and number two machines have input modules with
Siemens 6ES7 131-4BD01-0AB0 in them. Number three has input modules
Siemens 6ES7 131-4BD01-0AA0. How much of a difference is that 0AA0
versus 0AB0 and are they interchangeable? (It looks like the 0AA0 modules
are very expensive and the 0AB0 modules are much cheaper.)

Also, while the input modules appear to be more available, the output
modules 6ES7 132-4BD01-0AA0 look like e-Bay might be the best
source of. Or is there a more readily available alternative?

Many Thanks,
Poet.

0AB0 are what Siemens calls High feature while the 0AA0 are Standard.



Whether you can interchange them, will depend on how the program is done and whether it uses any of the High features in the module.

Thank you Mr. Cardosocea.
If the 0AB0's are 'high feature' . . . and the 0AA0 are standard, I would have
thought the 0AA0 would be cheaper.

A place called Allied Electronics has the 0AA0's for $230 for five.
And the 0AB0's are listed as $50 for five.

Oh well. We've had these machines for over ten years now . . . other machines for a
lot longer. (Including one with an A. B. PLC-5/25.) My boss jokes that he gets some
of our spare parts off E-Bay.

Don't know... in one of our suppliers we have the prices listed below:

131-4BD01-0AB0 - 180£
131-4BD01-0AA0 - 131£

Same here, 6ES7 131-4BD01-0AA0 is at approx 130€ list price for 1 pcs.
When you order them you typically have to specify them in boxes of 5 pcs.

10$ for 1 pcs. when ordering 5 pcs. does not sound right.
If the price is correct, can you reserve 500 pcs. for me

Dear Jesper,
I printed out the prices last week . . . from a place called 'Allied Electronics'.

Today I went back, and the 6ES7 131-4BD01-0AB0 is U.S. $247 for a pack of five.
(They also say zero in stock.)

I also visited a Siemens site which says both types of input modules have a
product phase-out of Jan 10, 2020.

The output modules have an end of product lifecycle of Jan 10, 2011.
(I take it this explains why I can't seem to find new ones to buy?)

Also, I got into the Step-7 configurations on my machines. The number one and
two machines - that rack is configured with the 0AB0 modules. The number
three machine is configured with the 0AA0 modules. (Input modules.)

If I was to buy the 0AB0 input modules . . and had to put them into the machine
with 0AA0 input modules - should it work? And will I have to go into the
configuration and change the module type?

Poet.

P.S. My machines are all working right now. But, last week we brought number
one down for several hours to replace a drive belt . . When powered back up the
ET200S was problematic . . . After a few power cycles it started acting right again
but I assume it will break again so I started checking on my spare parts and
availability and options for when it does go.

According to the Siemens support website, there is no discontinuation date:

The only way to check if you can replace -0BA0 with -0AA0 is to see in the properties of the -0BA0 if the "high features are not being used. If they are not being used, you can modify your HW Config to use -0AA0.

I've encountered failures in the terminal modules more than once, and those problems were nasty to narrow down.

Sorry, I misread... you want to replace -0AA0 with -0AB0.

You can, but you have to modify the HW Config... keep a note of the I/O address, because you have to delete the -0AA0 and add a -0BA0 in its place, and make the I/O address the same.

The "High Feature" version mostly just adds the ability to customize (in Siemenspeak, "parameterize") the reaction times of the Input state change. So you can for instance change the delay time for a transition foprm ) to 1 to be anywhere from 0.1ms to 15ms, whereas on the "standard" version, it is fixed at 2ms but they then say "typically 3ms" (so it is less predictable I guess). The High Feature version also provides for diagnostic feedback of the module and individual channels on it, the standard version does not. So if you use a Std. where the program was expecting a HF, there may be programming that is looking for the diagnostic data flags and since it will never see them, will continue on blissfully ignorant of the difference. But the timing issue might be getting in your way.


The HF version also has short circuit protection of the modules against an input going to ground (part of the diagnostics), the Std version does not.

You are missing an important bit here... because of the diagnostic bits, the high feature module will have a larger memory "footprint" that will impact the adjacent modules if the designer didn't leave a gap between the addressing.



This is easily checked in Step7 or TIA Portal.

Dear Sigmadelta,
The link brought me to the input module - and it looks like I can buy those.
But when I search at the link for the output module, no luck.

The successor part# is 6ES7132-4BD02-0AA0

Dear Mr. Cardosocea,
So, how do I check this in Step7?
Will I find it in the configuration . . . or am I going to have to look in the
function blocks or some other strange, weird, and wonderful place?

(For the record, I'm a maintenance tech . . . with delusions. . .)
