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, and BACnet/IP device onboard I/O, 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. Always use the recommended cables and wires.
The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, BACnet/IP devices, RP controller expansion modules, and Operator Display.
The EcoStruxure Building Operation software supports the major communication protocols in building automation and security management.
It is important to perform the grounding correctly for the following reasons:
There are many different kinds of external devices from different vendors that can be connected to an EcoStruxure BMS.
The override switches on Central IO modules with manufacturing date earlier than 2021-W26 must be disabled to remove the risk of an improper output. To disable the override switches, update the Central IO module firmware to version 2.017 or later.
The Status LED on the front of the automation devices changes color and flashes to indicate the status of the device.
The AS-P server offers enhanced processor performance, increased memory size, dual Ethernet ports, and high-speed USB interfaces. The AS-P server is a Schneider Electric manufactured embedded device that generally serves as the lowest tier EcoStruxure BMS server within the EcoStruxure BMS. The AS-P controls and supervises equipment, typically HVAC equipment. AS-P servers use Central IO module with connected field devices, such as sensors and actuators, to do that.
The Schneider Electric SpaceLogic hardware devices for the EcoStruxure BMS include terminal bases, PS-24V power supplies, Central IO modules, automation servers such as AS-P servers and AS-B servers, BACnet/IP devices such as MP-C controllers, MP-V controllers, IP-IO modules, and RP-C controllers, RP controller expansion modules, remote control, KNX Modbus gateway, Bluetooth adapter, Wireless Adapter - Advanced, SpaceLogic Sensor devices, Advanced Display devices, and Operator Display devices.
The UI-8/AO-4 and UI-8/AO-V-4 Central IO modules combine 8 universal inputs and 4 analog outputs.
