    keyword=target problem: loop 1 PID, fixed

    At ~3:00 pm, the TO called me. The target lifter was not
    working. Appearantly ioc crashed. After ioc reboot, adn gui restart,
    the loop 1 (LD2) PID stopped working. The TO tried reboot one moer time, but did not help. When I came to the counting house to look into it, the J-T control was also not responding. AFter switched
    gui from LOCAL to the ones from the target group, the J-T control
    was fine and all others are fine except loop 1 PID. With the help of Chris Keith from target group, we found that the power supply (hardware) control was fine, and the problem was only
    in the PID software. Chris Keith finally found a bug in the loop 1
    PID program and fixed it. After reboot, PID works now.
