Hello all,

I'm programming a system where I use OSCAT_BASIC.METER to track the capacity of a tank that is filled up and emptied. Initially, it works well, but after turning I1 off for a while it outputs NaN and the only way to get out of it is to reset the whole PLC from scratch. I'm attaching a picture of the inputs and output. RST doesn't help. All inputs are REAL. Output is a persistent variable. Attached screenshot of connections.

Would you kindly give me a hand if you know how to solve this? Thanks!
