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(jīng)過(guò)優(yōu)化，可控制小型HVAC機(jī)組、風(fēng)扇和地板供暖。它通過(guò)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(tǒng)中。
應(yīng)用?小型換熱站、風(fēng)扇和IRC的緊湊型I/O模塊
應(yīng)用程序、大型系統(tǒng)的附加模塊、數(shù)據(jù)采集。
功能RMIO包含輸入和輸出（4×模擬輸入，2×模擬輸出，4×數(shù)字輸入，7×數(shù)字輸出）。輸入和輸出通過(guò)RS485控制Modbus RTU。在單獨(dú)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(guò)電壓保護(hù)和電流隔離來(lái)自模塊的其他部分。如果模塊作為第一個(gè)或最后一個(gè)安裝在總線，將總線端DIP開(kāi)關(guān)設(shè)置為ON以終止總線。模塊已安裝在標(biāo)準(zhǔn)DIN導(dǎo)軌上。位于外殼內(nèi)部的兩個(gè)LED可實(shí)現(xiàn)快速診斷–權(quán)力和通信。
RMIO模塊固定在標(biāo)準(zhǔn)DIN導(dǎo)軌上（通過(guò)卡扣）。
所有模塊設(shè)置都備份在EEPROM芯片中。
有關(guān)連接示例，請(qǐng)參閱domat-技術(shù)應(yīng)用說(shuō)明。Modbus地址可設(shè)置如下：-硬件方面：使用DIP開(kāi)關(guān)。開(kāi)關(guān)增加了其位重量從右到左，參見(jiàn)示例圖，其中地址21是通過(guò)激活位權(quán)重分別為16、4和1的開(kāi)關(guān)4、6和8。有效的可設(shè)置范圍是1到254。地址0（所有開(kāi)關(guān)都關(guān)閉）表示地址設(shè)置為Modbus表中輸入的地址。地址255（所有開(kāi)關(guān)打開(kāi)）使模塊進(jìn)入INIT模式，其中Modbus地址為1通信參數(shù)設(shè)置為N、8、1，見(jiàn)下圖。在模塊關(guān)閉并再次打開(kāi)后，所有更改均適用軟件方面，使用ModComTool軟件，默認(rèn)地址（出廠設(shè)置）為1，默認(rèn)通信參數(shù)為9600、8、N、1。奇偶校驗(yàn)位和停止位可以在Modbus寄存器1005 LSB。
僅當(dāng)硬件尋址開(kāi)關(guān)設(shè)置為所有更改均在模塊關(guān)閉并再次打開(kāi)后生效。安裝RMIO模塊固定在標(biāo)準(zhǔn)DIN導(dǎo)軌上（通過(guò)卡扣）。
從DIN導(dǎo)軌上拆卸模塊時(shí)，請(qǐng)按以下步驟進(jìn)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(shè)備用于監(jiān)測(cè)和控制加熱、通風(fēng)和空氣調(diào)節(jié)系統(tǒng)。不得用于保護(hù)人員免受健康風(fēng)險(xiǎn)或死亡，作為安全元件，或在其故障可能導(dǎo)致物理?yè)p壞的應(yīng)用中或財(cái)產(chǎn)損失或環(huán)境損害。與設(shè)備操作相關(guān)的所有風(fēng)險(xiǎn)必須與整個(gè)系統(tǒng)的設(shè)計(jì)、安裝和運(yùn)行一起考慮設(shè)備所屬的控制系統(tǒng)。
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
