Connecting SmartX Sensors to an RP-C Controller

You connect SmartX Sensors to an RP-C controller to provide the sensors with power and communication from the controller.

action_close

The SmartX IP controller provides a sensor bus, which allows SmartX Sensors to be connected to the controller.

Aviso
LOSS OF COMMUNICATION Ensure that the total length of the sensor bus does not exceed 61 m (200 ft). Use a Cat 5 or higher unshielded twisted pair cable with eight conductors (four twisted pairs), a cross-sectional area of 22 to 26 AWG (0.34 to 0.14 mm ² ), and a rating that meets the requirements of the target environment. Failure to follow these instructions can result in loss of communication.

The last character (“n”) of this model number indicates the housing: X (Medium matte white), W (Optimum glass white), or B (Optimum glass black).
The SmartX resistive temperature sensor is not designed to be connected to the sensor bus, but instead is connected to I/O points/terminals on the SmartX IP controller using a two-wire connection.
The fourth character (“n”) of this model number indicates the housing: S (Medium matte white), W (Optimum glass white), or B (Optimum glass black).
The model number SXWSATXXXRXX is replaced by SLASXXX.
Connect the eCommission Bluetooth Adapter to the SmartX Sensor for temporary commissioning and servicing only.

To summarize the power conditions, the sensor bus supports the following key SmartX Sensor combinations:

Blank covers: Up to four sensors of any combination of sensor base types
3-button and touchscreen covers:
- Up to two sensor bases with CO ₂ option
- Up to four sensor bases without CO ₂ option
SmartX LCD temperature sensors: Up to four sensors are supported

Each SmartX Sensor has two 2-position DIP switches, which are used to give the sensor a unique address on the sensor bus. An incorrectly configured or improper DIP switch can cause two sensors to have the same address on the sensor bus, which means that both sensors will be offline.

Aviso
LOSS OF COMMUNICATION Ensure that the address DIP switches on the SmartX Sensor are configured to give the sensor a unique address on the sensor bus. Failure to follow these instructions can result in loss of communication.

Ensure that the address DIP switches on the SmartX Sensor are configured to give the sensor a unique address on the sensor bus.

Failure to follow these instructions can result in loss of communication.

Aviso

SmartX Sensors connected to the sensor bus through a daisy-chain configuration can be assigned addresses regardless of the order in which the sensors appear in the daisy chain. For example, sensor number 1 can have the address 4, sensor number 2 can have the address 3, and so on.

Aviso
LOSS OF COMMUNICATION Locate the sensor bus wiring away from external electromagnetic noise sources such as high voltage cables and Variable Frequency Drives (VFDs) for AC motors. Failure to follow these instructions can result in loss of communication.
