CMC-BC (Communication Modem Controller ：Base Controller) This is an interface unit to handle the signals from/to the vehicle controller. It also serves as the multiplexer for several CMC-BM units. CMC-BC can work in two different modes, master mode and slave mode. It allows the user to use the multiple units according to the scale of the conveyance system. The CMC-BC unit may vary in its outward form depending on the conveyance system. However, the internal configuration is common. Figure 4 shows the block diagram of CMC-BC. Figure 5 shows the outward form of the CMC-BC’s main printed circuit board NBV-BC. Figure 6 shows for example the outward form of the CMC-BC unit. 3.3.2. CMC-BM(Communication Modem Controller ：Base Modem) This is a modem unit to handle the signals from/to several vehicles. It incorporates a driver that modulates the digital signals sent from CMC-BC to analog signals and overlay the converted signals onto the non-conductive power line or signal line. It also demodulates the analog signals sent from the vehicles to digital signals and transmits them to CMC-BC. The CMC-BM unit may vary in its outward form depending on the conveyance system. However, the internal configuration is common. Figure 4 shows the block diagram of CMC-BM. Figure 7 shows the outline form of the CMC-BM’s main printed circuit board BV-BM2. Figure 8 shows for example the outline form of the CMC-BM unit. 3.3.3. CMC-TR(Communication Modem Controller ：TRansformer) Transmission transformer overlays the signals from CMC-BM onto the non-conductive power line or signal line. The reception transformer receives the signals from vehicles overlaid in the non-conductive power line or signal line. Figure 9 shows the outer forms of the transformers.
Muratec Automation Co., Ltd.Muratec Automation Co., Ltd.Muratec Automation Co., Ltd.Muratec Automation Co., Ltd. 12 3.4. The Block Diagram of CMC Fig. 4 The block diagram of CMC CMC is a communication unit between a vehicle controller and vehicles. The communication signals modulate current signals of a power line/or signal line . The vehicle controller controls vehicle movement by transmitting and receiving this signal. [CMC-BC] Communication signals from the vehicle controller are transmitted to CMC-BC as RS232C or RS485. When communication signal is “1”, The Modulator of CMC-BC modulates 285.7 kHz FSK signal frequency. When communication signal is “0”, The Modulator of CMC-BC modulates 315.8 kHz FSK signal frequency. The modulation signal is transmitted to CMC-BM through a line driver of RS485.This modulation signals transmit to CMC-BM as RS485. [CMC-BM and CMC-TR] The modulation signal is received from CMC-BC through a line receiver of RS485. TX Amp of CMC-BM is full bridge inverter. The modulation signals are converted into a gate signal of full bridge inverter. The inverter transmits the modulation signal through resonance circuit and CMC-TR.

Error process [Note.1] Before servicing CMC-BC，CMC-BM，CMC-TR，always shut off the power supply. [Note.2] If the communication signals are overlaid onto the non-conductive power line, also shut off the power source of the non-conductive power line before starting maintenance on CMC-BM and CMC-TR. <Communication error trouble shooting> Vehicle Controller issues a communication error Is Vehicle Controller sending communication signals? Check the settings for Vehicle Controller. Are the power indicator lights of CMC-BC and CMC-BM illuminated? Is the power supply of 200V AC 1φor 100V AC 1φ50/60Hz connected? Is the input fuse burnt? Replace the fuse. Turn the power supply OFF. Is the input resistance of the DC power almost 0 ohm? Replace the DC power supply. Is the power LED of the print circuit NBV-BC illuminated? Is the power LED of the print circuit BV-BM2 illuminated? Replace the print circuit board Is the connection between CMC-BM and CMC-TR normal? Restore connection. END
