Hello @madmike, It looks you are doing the right thing and you should be able to see the values of your local array. Is the function you are currently monitoring constantly called from main function? When monitoring a function, there is a banner on top of the ladder dockable, which can be either green if all tags values are up to date, orange, if monitored function is not currently called, or red if monitored function was never called. Can you please confirm that the banner is green by you? Are you able to see values of other local /function In tags? Have a good day, Rivka -
Please check jumpers. Yoou must set 4 jumpers for set AN0 and AN1 analog input to current mode. Please post your multimeter connection setup diagram for test transmitter curent value. -

Thank you for getting back to me. Currently I am trying to diagnose what is wrong, but I should have provided more details. The main goal of the program is to display both the raw data (which the load cell transmitter sends in the form of 4-20mA) and linearized decimal output of the load cell on the PLC. Currently the raw data is being displayed as zero and is not changing when a load is placed on the load cell. I used a multimeter to test the current outputted by the transmitter and it was correct, so the error is occurring somewhere either in the input wiring to the PLC or in the programs handling of the analog input. If there is anything still unclear let me know and I will try to go into more detail! (I did change the MI 0 & MI 1 to displaying 4 digits, unfortunately it didn't solve the overarching problem, but it was a good catch nonetheless.) -
Hi all, i am using version 1.39.103 and trying to monitor my UDFB online. I can't see the tags update in the tag fields, under the test column it says the tag has not been allocated yet. Is there a way to monitor for example an array in a UDFB? I do right click on the UDFB in the main module and click monitor. -
Can you provide a few details as to what exactly does "not functioning" mean? This is like saying "my car won't start" - can you tell me what's wrong? Looking at your project file, everything there seems correct, with the exception of the display of MI 0 & MI 1. Both of these could be 4 digit numbers, but you have only allocated 3 digits to the HMI element.
