This section provides recommendations on minimum wire sizes (cross-sectional areas) and maximum wire lengths for the wires connected to the screw terminals of Central IO modules, AS-P-3 server, AS-B servers, RP and MP controllers, and IP-IO and RP-IO I/O modules. Recommendations on minimum wire size and maximum cable length for the digital inputs of the RP controller expansion modules, the DALI bus of the DALI light modules, the SMI Interface of the SMI blind modules, the Zigbee DALI and 0-10V modules, and the KNX Modbus gateway are also provided. The recommendations are for guidance only. Other wire sizes and lengths may be used, depending on wiring rules and when appropriate.
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
The EcoStruxure Building Operation software supports the major communication protocols in building automation and security management.
You print an I/O wiring list for the I/O bus that describes which I/O points are associated with each I/O module. You use the printed copy of this list to help wire the I/O bus network.
You print labels to identify I/O channels on the placard of an I/O module much the same way you label circuits on an electrical panel. You accept the default names for the I/O point labels or customize the I/O point names for your own application.
Use the power budget to calculate the maximum number of Central IO modules that the AS-P-3 server can supply. If more I/O modules are used, PS-24V power supplies must be added to the I/O bus.
The I/O bus is a common bus that delivers power, address information, and communication to all devices connected to the bus. The term I/O bus also denotes the chain of devices that are connected together.
The I/O bus imposes restrictions on the number of devices that can be connected to the bus and what type of devices that are allowed on certain positions.
The I/O bus consists of the following parts:
The Schneider Electric EasyLogic and SpaceLogic hardware devices for the EcoStruxure BMS include terminal bases, PS-24V power supplies, Central IO modules, automation servers such as AS-P-3, AS-P and AS-B servers, MP-C, MP-V, RP-C, and RP-V controllers, IP-IO and RP-IO I/O modules, RP controller expansion modules, remote control, KNX Modbus gateway, Bluetooth adapter, Wireless Adapter - Advanced, SpaceLogic Sensor devices, Advanced Display devices, and Operator Display devices.
