IN AC31GRAPH Software of ABB PLC: MULTIPLICATION BY 2 TO THE POWER OF N is available. (page 185:https://katalog.vaeprosys.cz/assets/doc/106 ABB AC31 Graf Software.pdf). Example 3 is Input value E1 = -32612 (8008H) .
Exponent N = -3 -> 3 * Right shift . Here result after 3 shifts is shown as : 1.1.1.1 0.0.0.0 0.0.0.0 0.0.0.1 (LSB). I aggree that Bit 15 is =1 (for negative sign). Why Bit 14 and Bit 13 came as 1?
