sinumerik possibly?

Is this on a CNC piece of equipment? The only info I could find for a "Siemens" FB199 is for a sinumerik 840 system...

5.22 FB 199 FIFO
​

First in first out (turning version)
​

for SINUMERIK 880/880 GA2 and package 2 only
​

Description
​

The FB "FIFO" is used to enter data that are provided at a high speed in a data buffer. These
​

data can be read later, i.e. when required. A maximum of 255 data lines can be stored by means
​

of this block. The DBs for the buffer entries are created at the initial setting.
​

Optionally, three or four data elements can be stored via the "DBAN" parameter (first DB and
​

number of DBs). The user has to make sure that the respective value is entered in this parameter
​

at the initial setting.​

You can ignore this post if it is not a CNC...​

Thank you very much!
It is not CNC, but it is called right after a call for FB178(counter). Maybe it is similar as FIFO.
