Working on A320 ? or in near future ? Interested ? Take a look into A320 GEN FAM to provide basic and important knowledge in this particular aircraft type.
560RTC01 – GPS receiver unit 23BA22 – Binary output monitoring unit
RTU 560 Hardware RTU hardware are base on European standard card format 100 x 160 mm. RTU 560 principle is built by one or two main subrack containing the communication and processing unit with serial or ethernet interfaces and I/O subracks with the I/O board. 2 types of RTU configurations: RTU 560A
The I/O subrack connected to CMU’s with serial RS 485 interface A or B.
RTU 560 Bus connection Bus connection not only provide system bus connection between CMUs it also provide system signals Local Alarm (relay contact) Local warning TSI (time sync input signal)
Each slot has it own slot and board addresses. Only the first slot is dedicated for the power supply, the rest are freely configurable for any board type.
RTU 560 Component : Serial peripheral bus
X1/X2 allows extension of serial peripheral bus to other sub rack.
Use 3 wire, direct tx, rx and ground. (shielded cable)
RTU 560 Component : Serial peripheral bus Other possibilities ! For a longer distance linked or grounding situation very bad electrical serial peripheral bus could be replaced by optical fibre connection.
Option 2 :- serial peripheral bus in multipoint-T-configuration.
RTU 560 Component : Bus connection unit Bus connection unit is designed to make system bus signal accessible to multiple MPU . BCU card provide Alarm and Warning signal to outside relay contact. It also provide input/output for I/O time synchronization. (24 Vdc optically isolated) 3 type of BCU for 3 different rack. BCU01 for 560CSR01 sub rack. BCU02 for 23TP23 sub rack. BCU03 R001 for 23ET23 sub rack.
BCU 03 mounted on PBP connectors X1 and X2 on 23ET23.
560 BCU03
560 BCU01
560 BCU02
RTU 560 : Bus connection unit mounting For BCU03 R0002, it is mounted at the back of 23ET24 with 4 plastic bolts The connection to CMU module is by ribbon cable (max 2 unit of CMU could be connected this way)
It is also to activate the interposing module 23BA30
RTU 560 Component: Binary input board Binary input board is 23BE21. 16 Binary input channel which scanned every ms. 23BE21 support Single indication Double indication Pulse counter value input
RTU 560 Component: Analogue input board 23AE21 board allow separately for each of the input channel to be configured Zero value supervision Switching detection Smoothing Cyclic transmission to CMU independent from treshold supervision Treshold supervision
RTU 560 Component: Binary Output board Command output monitoring provided by 23BA22 board (1 out of n check) Two type of object command supported 1 or 2 pole output without (1 out of n check)
EAP – input/output processor activate any output forced by CMU by a command output request. EAP provide time duration of a pulse output loaded by CMU to RAM.
RTU 560 Component: Analog Output board EAP – input/output processor controls 2 digital to analog converter. DAC resolution is 11 bit + sign Output value remain until new value receive.
GPS signal drop > 2.5 hr 560RTC01 not sync. Power source lost Watchdog timer of the EAP operated.
RTU 560 Component: Real time clock Antenna mounting. BNC front plug for coax cable (50 ohm, RG 58, max 200 m) RJ 45 connector provide a RS 232 interface which offering 33 byte of ASCII coded time message every minute.
RTU 560 Component: CMU05 560 CMU05 provide ethernet interface CMU (communication unit) for RTU 560. Main tasks are Managing and controlling I/O boards via up to 2 peripheral bus. Reading process event from the input board. Writing command to the output board.
Communication with control center and local MMI system via ethernet 10/100baseT LAN Managing time base and synchronisation of I/O board. Handling dialogue with PC based data engineering and diagnostic tool RTUtil NT via LAN Interface
RTU 560 Component: 560ETH02/03 2 microprocessor MPU 32 bit main processing unit SLC 8 bit serial line controller
RTU 560 Component: 560ETH02/03 By default X1 jumper is always at position 1-2 If the jumper is at position 2-3 then it will read IP from the configuration set The default IP is 192.168.0.1
RTU 560 Component: Power supply unit 560PSU01 560PSU01 generate 2 type of supply voltage 5 V dc and 24 V dc. 2 type of input supply 24 to 60 V dc (-20% +15%) 110 to 220 V dc ( -20% +15%)
