Concept
The RS-485 Power Adapter can be used for injecting 24 VDC from an external 24 VDC power supply to an RS-485 based network such as Room Bus or Sensor Bus. This is useful, for example, in applications where you want to extend the RS-485 bus by connecting (daisy-chaining) additional devices, which the RP or MP controller would otherwise not be able to power. The external power supply is connected to the bus via the adapter.
Concept
The MP controller Modbus RTU (RS-485) subnetwork allows standard Modbus devices to be connected to the controller. An adapter is required for converting the controller RS-485 Com port with RJ45 interface to screw terminals.
Concept
You can reset and restart the IP-IO and RP-IO modules in different ways depending on how long you press the reset button. The resets and restarts can affect the retention of values after restart based on the retain levels configured for the variables.
Concept
This section provides information on regulatory compliance and approvals for the RS-485 Adapters.
Concept
This section provides grounding and power recommendations for system configurations with MP controllers.
Concept
The analog outputs are capable of supporting analog voltage or current point types. Therefore, analog outputs support a wide range of devices, such as actuators.
Concept
The universal inputs are ideal for any mix of temperature, pressure, flow, status points, and similar point types in a building control system.
Concept
The communications on the BACnet MS/TP (RS-485) bus occurs at a user-defined baud rate. You must configure the baud rate for the automation server RS-485 bus(es) as part of the commissioning process for the RP and MP controllers and RP-IO modules that support MS/TP communications.
User Interface
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
Concept
The I/O wiring recommendations provide guidance on what type of wires should be used for the different Central IO modules, AS-B server onboard I/O, RP and MP controller onboard I/O, and IP-IO and RP-IO I/O modules, how to perform grounding, and how to connect different external devices to the inputs and outputs. This section also provides information on the external connectors required for the RP controller expansion modules and the RP-C-16C-F-230V model. Always use the recommended cables and wires.
