The MP-V sensor bus allows SpaceLogic Sensor devices to be connected to the controller.
Notice
|
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.

By default, the MP-V controller's RS-485 Com A port is configured and allocated for the sensor bus.
For more information, see MP-V Communication Ports

Note:
When connecting SpaceLogic Sensor devices to the sensor bus through a daisy-chain configuration, the sensor bus ports on the SpaceLogic Sensor are interchangeable.

To summarize the power conditions, the sensor bus supports the following key SpaceLogic Sensor combinations:
Blank covers: Up to four sensors of any combination of sensor base types
3-button and touchscreen covers:
SpaceLogic LCD temperature sensors: Up to four sensors are supported
Note:
The RS-485 Power Adapter can be used to supply 24 VDC power to the MP controller sensor bus so that the maximum number of sensor bases with CO
2
option can be increased from two to four sensor bases. The adapter can be ordered from Schneider Electric using the part number SXWNISORS485P10001.

Figure:
Examples with one SpaceLogic Sensor and four SpaceLogic Sensor devices connected to an MP-V controller in a daisy-chain configuration
Each SpaceLogic 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.

LOSS OF COMMUNICATION
Ensure that the address DIP switches on the SpaceLogic 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.
|
Note:
SpaceLogic Sensor devices 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.
