Abstract: A system includes an input/output module (IOM) configured to interface with a field device. The IOM includes a terminal block including a plurality of inputs or outputs, each of the inputs or outputs configured to send and receive signals to and from the field device. The IOM also includes a plurality of temperature sensors, each of the plurality of temperature sensor configured to measure a temperature in a vicinity of the temperature sensor. The IOM also includes a connector configured to transmit the temperature of each of the plurality of temperature sensors to a processing device.

Abstract: A controller unit for communicating with and controlling one or more discrete air conditioner units within a building is disclosed. In some instances, the discrete air conditioner controller may be configured to receive signals in a first signal format from a central coordinator and to transmit signals to the one or more discrete air conditioner units in a second signal format. The first signal format and second signal format may be different wireless formats. In some cases, the controller unit may store a programmable operating schedule, which may be updated via the central coordinator.

Abstract: A building control system that includes a central coordinator and one or more discrete air conditioner controllers configured to communicate with one or more discrete air conditioner units. The discrete air conditioner controller may include a wireless I/O block for receiving signals in a first signal format from the central coordinator and for transmitting signals to the one or more discrete air conditioner units in a second signal format. In some instances, the discrete air conditioner controller may be configured to wirelessly transmit a signal to at least one discrete air conditioner unit in response to receiving a signal from the central coordinator. This configuration may provide a measure of distributed control of the building control system in a cost effective and efficient manner.

Abstract: A method of FSK decoding includes generating a pulse waveform (R'Edge) from a received FSK encoded signal (FSK signal) and a system clock (Sys_clk). From R'Edge and Sys_clk clocks are generated including a first clock and second clock framing a logic ‘0’ level of the FSK signal, and a third clock and fourth clock framing a logic ‘1’ level of the FSK signal. At least four frequency envelopes are generated from the clocks including a logic ‘0’ envelope, a logic ‘1’ envelope, a lower frequency envelope below the logic ‘0’ envelope, and an upper frequency envelope above the logic ‘1’ envelope. R'Edge is compared to the four envelopes, and a decoded output is produced, logic ‘0’ if the R'Edge overlaps the logic ‘0’ envelope, logic ‘1’ if R'Edge overlaps the logic ‘1’ envelope, and a previous output state if R'Edge does not overlap the logic ‘0’ or logic ‘1’ envelope.

Abstract: A method for sensing modulated signals in a process facility. The method includes providing a monitoring device that includes a non-contact electromagnetic sensor (EM sensor) configured to sense a modulated signal transmitted on a cable including a conductor coupled to a sensing device or apparatus in the process facility. The monitoring device further includes a non-transitory machine readable storage device and a processor. The non-transitory machine readable storage device stores a data decoding program including protocol information for identifying different communication protocols. The monitoring device is positioned in proximity to the cable for the EM sensor to detect the modulated signal. The data decoding program is implemented by the processor causing the processor to detect the modulated signal and condition the modulated signal to provide a conditioned modulated signal. The conditioned modulated signal is decoded to generate decoded signal data, and the decoded signal data is displayed.
