An improved flow rate metering device that provides for the mixing and dispensing of two or more fluids to form final mixture, for example, for automatic washing of cars and trucks. More specifically, the invention is a system that mixes and ejects chemicals, creating a very precise mixture of one or more chemicals with a dilutant, such as water. The device also has the capability of monitoring an entire chemical dilution and release system, comprising multiple chemicals, and using software to document past and current usage rates, along with predicting future usage rates based upon both past usage rates and environmental conditions.

Various examples of the present invention provide a server for providing information of an electronic device, and the server can comprise: a communication unit for receiving, from at least one first electronic device, at least one piece of information of the first electronic device; and a control unit for determining, from the received information, a current state among a plurality of states preset for the first electronic device, and controlling the first electronic device such that state prediction information of the first electronic device is transmitted to a second electronic device if the determined current state satisfies a preset notification condition on a state diagram in which a relationship among the plurality of states is set. Additionally, other examples could be possible besides the various examples of the present invention.

An input module for an industrial controller includes configurable execution windows. The execution windows are defined by a first parameter and a second parameter stored within the input module. A third parameter defines a status bit which is compared against the execution window to set a window output signal within the input module. The execution window may define a range between the first and second parameters against which the status bit is compared. Alternately, the first and second parameters may define setpoints against which the status bit is compared. At one of the setpoints, the window output signal is set and at the other of the setpoints, the window output signal is reset.

An input module for an industrial controller is configurable to simplify setup and commissioning. The input module includes input terminals configurable, for example, as a counter input. Still other input terminals may be configured to trigger events as a function of the input signals present at the terminals. Time signals corresponding to transitions in state of the input terminals, triggering of events, or operation of the counters may be recorded. The input module is further configurable to transmit data back to the processor or to transmit data directly to another module in the industrial control network.

An output module for an industrial controller configurable to simplify setup and commissioning is disclosed. The output module includes configurable PWM outputs that may be scheduled to start at different times within the PWM period, that may be configured to generate a fixed number of PWM pulses, and that may have an extendable PWM period. The output terminals are configurable to enter a first state upon generation of a fault and further configurable to enter a second state after a configurable time delay following the fault being generated. The output module may receive inputs signals directly from another module and set output signals at the terminals responsive to these signals.
