There are provided methods and devices for use with industrial control systems. For example, there is provided a method that can include acquiring data from a sensor associated with an industrial machine. The method can include determining, while acquiring the data, whether at least one condition is satisfied in the data. Furthermore, the method can include logging the data as a function of time and logging information associated with the at least one condition as a function of time, in response to the at least one condition being satisfied. The method can also querying the logged information, subsequent to logging the data, to identify subsets of the data for which the at least one condition is satisfied.

Methods, devices and systems capable of performing a hot restart of a compressor driven by a turbine are provided. The turbine has a high speed shaft and a low speed shaft connected to the compressor. A base slow roll speed at which a speed of the low speed shaft is in a slow roll range is maintained at the high speed shaft for a predetermined time. Then, when a vibration amplitude of the compressor is larger than a vibration limit, the maintaining is repeated. Otherwise, a set speed of the high speed shaft is increased, until a current speed of the low speed shaft reaches a minimum operating speed. If, while increasing the set speed, the vibration amplitude becomes larger than the vibration limit, the maintaining is repeated.

Methods and devices for performing a low torque low speed test to determine whether a rotor of a turbomachinery is free to rotate are provided. A method includes automatically applying a torque to the rotor, the torque gradually increasing up to a predetermined torque value. The method further includes monitoring the speed of the rotor while the torque is gradually increased. The method also includes outputting an indication that the rotor is free to rotate after the speed of the rotor becomes positive, or outputting an indication that the rotor is locked when the speed of the rotor remains zero and the applied torque has reached the predetermined torque value.
