Hello,

I'm trying to retrieve a timer variable from PLC under the type of Word (DB608.DBW0). The timer value in the HMI should be 10s.  
The problem is that when I try to retrieve it in node red (DB608,WORD0) , I get a different value = 136. It's a bit confusing and I don't know where is the problem ?
