How this function works

Thank you very much for your great help 

I am still editing the program  in order to have the readings in the HMI,  Yet still have this problem 

To imagine the situation: There are two meters, in each meter, there are three pressure transmitters 

Meter #1 PIW 464, 466 and 468  ( average of three  ) shown in the HMI

Meter #2 PIW 472, 474 and 476 ( average of three )  shown in the HMI

The outlet of both meters is then connected together and there are also three pressure transmitters in the outlet 

Outlet meterS:  PIW416, PIW418 and PIW420 ( average of three ) 

The problem the only  FC6, please see the attachment,  is activated for the meter 1 while meter2 and outlet show 0 in the HMI

I checked the PIW inside each block for meter #2 and the outlet,  they read ok.  

My question why the middle and the right FC6, meter#2 and outlet meterS respectively. do not show reading in monitoring mode? although when I open the blocks the  #0ut5 for each block read 26.9  same as FC6 for meter# 1

do I need to enable them by a command  for example 

Hello Daniel 

Thank you so very much for your reply and concern. I highly appreciate your response 

I am attaching herewith this post the original FC6 content ( printed, please see the pdf). I have marked the changes I made in a blue pen

Also, I have split the networks i.e each FC6 in now in a standalone network NW27,28, and 29

because I can not see the point of making them in one network so if one fails the other two one follow suits 

I am forward to hearing your comments on changes I made plus how to get the ENO of the left FC6 activated so to enable the second and the third ( in case I left them all in one  NW) 

Regards 

Thank you very much 

So I have two solutions either I create ENO inside the FC, which I do not know how to do it.( I would most grateful if you could help )

or I put each FC in a separate network, right?

However, Did the changes ( in pen) made sense to you, I wonder?

I truly can't thank you enough for your long-standing support 

You can make a change in the FC.

Insert at last a STL network with the two instructions:

SET
SAVE

Or (I personally found it better) for every FC6 a own network.

 I have checked other FC blocks which are connected in series to check how they work. Yes, I found the first one (the one on the left) ends with 3 networks but empty !
