140CPU67160S安裝熱備CPU模塊
緊湊型I/O模塊
摘要RMIO是一種通用、緊湊、微處理器控制的通信模塊其I/O組合經過優化，可控制小型HVAC機組、風扇和地板供暖。它通過RS485總線與Modbus RTU（從屬）通信，因此可以很容易地集成在一系列控制系統中。
應用?小型換熱站、風扇和IRC的緊湊型I/O模塊
應用程序、大型系統的附加模塊、數據采集。
功能RMIO包含輸入和輸出（4×模擬輸入，2×模擬輸出，4×數字輸入，7×數字輸出）。輸入和輸出通過RS485控制Modbus RTU。在單獨的文檔中查找Modbus寄存器表。通用緊湊型模塊RMIO是舊MMIO模塊的替代品。
通信電路有過電壓保護和電流隔離來自模塊的其他部分。如果模塊作為第一個或最后一個安裝在總線，將總線端DIP開關設置為ON以終止總線。模塊已安裝在標準DIN導軌上。位于外殼內部的兩個LED可實現快速診斷–權力和通信。
RMIO模塊固定在標準DIN導軌上（通過卡扣）。
所有模塊設置都備份在EEPROM芯片中。
有關連接示例，請參閱domat-技術應用說明。Modbus地址可設置如下：-硬件方面：使用DIP開關。開關增加了其位重量從右到左，參見示例圖，其中地址21是通過激活位權重分別為16、4和1的開關4、6和8。有效的可設置范圍是1到254。地址0（所有開關都關閉）表示地址設置為Modbus表中輸入的地址。地址255（所有開關打開）使模塊進入INIT模式，其中Modbus地址為1通信參數設置為N、8、1，見下圖。在模塊關閉并再次打開后，所有更改均適用軟件方面，使用ModComTool軟件，默認地址（出廠設置）為1，默認通信參數為9600、8、N、1。奇偶校驗位和停止位可以在Modbus寄存器1005 LSB。
僅當硬件尋址開關設置為所有更改均在模塊關閉并再次打開后生效。安裝RMIO模塊固定在標準DIN導軌上（通過卡扣）。
從DIN導軌上拆卸模塊時，請按以下步驟進行：將螺絲刀放入位于模塊（1）底部中間的塑料槽。
然后按螺絲刀向上（2）。然后，向上傾斜模塊即可將其拆下該設備用于監測和控制加熱、通風和空氣調節系統。不得用于保護人員免受健康風險或死亡，作為安全元件，或在其故障可能導致物理損壞的應用中或財產損失或環境損害。與設備操作相關的所有風險必須與整個系統的設計、安裝和運行一起考慮設備所屬的控制系統。
Compact I/O module Summary
The RMIO is a universal, compact, microprocessor controlled, communicative module with its I/O mix optimized for control of small HVAC units, fancoils, and floor heating. It communicates over a RS485 bus with Modbus RTU (slave) and thus can be easily integrated in a range of control systems. Application ? Compact I/O module for small heat exchange stations, fancoils and IRC applications, add-on module for larger systems, data acquisition. Function The RMIO contains inputs and outputs (4× analogue input, 2× analogue output, 4× digital input, 7× digital output). The inputs and outputs are controlled over RS485 with Modbus RTU. Find the Modbus register table in a separate document. The universal compact module RMIO is replacement of the older MMIO module. The communication circuits are protected against overvoltage and galvanically isolated from other parts of the module. If the module is installed as the first or the last on the bus, set the BUS END DIP switches to ON to terminate the bus. The module is installed on a standard DIN rail. Two LEDs located inside of the housing enable fast diagnostics – power and communication. The RMIO module is fixed on standard DIN rail (by snapping). All module settings are backed up in an EEPROM chip. See domat - Technical application notes for connection examples.
The Modbus address can be set as follows:
- hardwarewise: using DIP switches. The switches increase their bit weight from right to left, see image with example where address of 21 is set by activation of switches 4, 6, and 8 with bit weight of 16, 4, and 1 respectively. Valid settable range is 1 to 254. Address 0 (all switches OFF) means that the address is set as entered in the Modbus table. Address 255 (all switches ON) brings the module to INIT mode, where Modbus address is 1 and communication parameters are set to N, 8, 1, see image below. All changes apply after the module is switched off and on again.- softwarewise using the ModComTool software, available for free at www.domat.cz. The default address (factory setting) is 1, default communication parameters are 9600, 8, N, 1. Parity and stopbits can be set in Modbus register 1005 LSB. The software address is only active if the hardware addressing switch is set to 0. All changes apply after the module is switched off and on again. Installation The RMIO module is fixed on standard DIN rail (by snapping). When removing the module from the DIN rail proceed as follows: Place a screwdriver in the plastic slot which is in the middle of bottom part of the module (1). Then push the screwdriver upwards (2). After that, the module can be removed by tilting it upwards
