Hello all,
I have created a new fb but for some reason when I loaded it into the PLC and attempted to monitor the block it is not outlined showing that it is working. Instead of the normal hilight, all I see is a dotted line for the outline of the block. All this fb is doing is parsing a string and writing the results into a db. It also does some sequencing functions but nothing major. This is what I have done up to this point with it. I created an instance db and associated it with this fb. Both have been saved and downloaded into the controller. Everything monitors and checks out. I can even monitor the fb that I created. I have also added logic into the fb and simply set a bit from the fb and monitored it in a vat table to verify that the block is working. But it just doesn't look right on the outside when I monitor. I have not been able to "turn on" this logic yet because it can't be used during normal operation of our plant. Can anyone tell me why this block doesn't hilight when I monitor it. I have done all of this before and it has never looked like this. Sorry if I have rambled in this question. Thanks for the help.
