The RP controller Modbus RTU (RS-485) subnetwork allows standard Modbus devices and the KNX Modbus gateway (RP-C-EXT-KNX) to be connected to the controller.
The KNX Modbus gateway (RP-C-EXT-KNX) is equipped with two 3-position pluggable screw terminal blocks for connection to the RP-C Modbus (RS-485) network and a 2-pole PCB connector for connection to the KNX bus.
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 KNX Modbus gateway RP-C-EXT-KNX connects to the RP-C controllers and provides an interface between the controller and KNX devices such as push-buttons, sensors, and control units for lights, blinds, and room temperature.
You install a KNX Modbus gateway (RP-C-EXT-KNX) on a DIN rail to properly fasten the device and to allow for sufficient ventilation.
There are two push-buttons on the front of the KNX Modbus gateway (RP-C-EXT-KNX) and one button above the front. The buttons are used to activate or deactivate various modes.
The KNX Modbus gateway (RP-C-EXT-KNX) is designed for installation on a DIN rail. The width of the device is 1 unit (18 mm or 0.7 inch).
There are three LEDs on the front of the KNX Modbus gateway (RP-C-EXT-KNX) and one LED above the front. The LEDs indicate different types of status and modes.
