ControlStandardLib 1.4-7 Pidcc Block problem

Hi all

I am facing a problem in ControlStandardLib 1.4-7 Pidcc Block PID_OUTPUT . Sometime the OUTPUT of the PID gives a very large number (i.e -1.#J or 1.$) which is beon the output range (0-100). we even the MV and SP seem to be good . Trend Display is attached with it .. RampSoak is the SP for PID . Can anyone please suggest anything regarding this problem .

Thanks in Advance
