"Non-burning, nicotine for users, low tar content. As the heating temperature (below 500℃) is lower than the combustion temperature of traditional cigarettes (600-900℃), the harmful components produced by tobacco high-temperature combustion pyrolysis and thermal synthesis are reduced, and the release amount of side-flow smoke and environmental smoke (second-hand smoke) is also greatly reduced."
Heating non - combustion products are electronic devices containing tobacco. When you heat them, they produce a nicotine-containing vapor that you can inhale. Hnb Device Oem,Hnb Device Patent,Hnb Device,Hnb Device For Sale Shenzhen MASON VAP Technology Co., Ltd. , https://www.e-cigarettefactory.com
2: How do I get some system status inside Quantum? And the status of each I/O module in the RIO or DIO substation? In the concept of IEC programming in Concept, some system states in Quantum can be obtained through the function block plcSTAT. The output PLC-STAT of this function block contains 11 words, RIO-STAT contains 160 words, and DIO-STAT contains 106 words. Words, note that the output of this function block, DIO-STAT, is only related to the status information on the RIO substation, not the information on the DIO substation. To get the status of an I/O module on a RIO drop or a DIO drop, use the function block RIOSTAT or DIOSTAT respectively.
3: Can the Quantum Interrupt Latch Module 140HLI34000 be used in a dual hot standby system? Is IEC programming in Concept, is there an interrupt instruction? The interrupt latch module can only be used in a local rack and cannot be used on RIO or DIO substations, so it cannot be used in a dual hot standby system. Only 984LL has interrupt processing instructions in Concept. Quantum interrupts have hardware-based interrupts and timer-based interrupts. All interrupt instructions are under 984LL/Fast I/O Instructions. There is no interrupt instruction in the IEC.
4: What should I pay attention to when configuring Quantum Remote I/O (RIO)? The RIO structure is based on the I/O networking of the S908. The transmission medium is a coaxial cable. Note that when configuring: 1: RIO can have up to 31 substations. 2: Each RIO substation, up to 64 words input, 64 words output. This word limit includes discrete and analog quantities. 3: RIO has a transmission distance of 4572 meters (15,000 feet) without repeaters. If fiber optic repeaters are used, the total length of the network can reach 13 kilometers. 4: Quantum dual hot standby supports RIO architecture.
5: If it is connected to a dual redundant MB+ network, is there a requirement for the length of CableA and CableB? In order to reduce the chance of the dual redundant MB+ network being interfered or damaged at the same time, it is recommended that the user CableA and CableB run separately, and The system also has requirements for the length of CableA and CableB, that is, the total length difference between CableA and CableB between any nodes on the MB+ network must not exceed 500 ft (150 m). Example: If the total of CableA between Node 1 and Node 6 on the MB+ network The length is 200 meters, and the total length of CableB is 100 meters, 200-100=100<150m, which meets the requirements.
6: Is it feasible to have Quantum remote I/O distributed in both directions of the primary station? feasible. There are two common scenarios:
1: There are dual cable ports on the RIO processor, and there is a single cable port on each RIO substation adapter, so that there are two linear cables from the RIO processor's two cable ports along separate routes to different remote points. Station device. The length of the trunk cable and the number of substations on each trunk cable are not required to be balanced in this dual cable system. In most cases, the installation of the two lines can be seen as two separate cable systems. However, it must be noted that the total number of substations on both lines must not exceed the maximum number of substations supported by the PLC. Each substation on the two trunk cables must have a unique RIO network address. 2: The fiber optic cable topology using fiber optic repeaters can also achieve RIO substation distribution in both directions of the main station. The detailed topology can be found in the Modicon Remote I/O Design and Installation Manual.
7: How many RR85 repeaters can be installed in an MB+ network or a DIO network? Up to three RR85 repeaters divide the network into four segments with a distance of no more than 450 meters, so that the network distance transmitted by twisted pairs can reach 1800 meters.
8: How to configure MB+ fiber network for Quantum PLC? There are two options. The first one can use the MB+ port or NOM template on the CPU to form an MB+ fiber network through the fiber repeater 490NRP25400 or 490NRP25300. Another solution is to directly use the MB+ fiber template 140NOM25200. Since the NOM25200 has built-in MB+ fiber communication support, it does not need to be connected to a photoelectric converter, and can be directly connected to the fiber. There are four topologies: Point-to-Point, Bus, Star and Tree, and Self Healing Ring. The Self Healing Ring configuration has all the advantages of the above configuration and is redundant. A disconnect between any two Quantum templates on the ring will automatically reconfigure the network into a bus configuration and continue communication. 9: When using the Quantum expansion module 140XBE10000 to expand local I/O, can I increase local I/O input and output words? No, after adding the expansion module, the input of the local I/O of the two racks, the output word is still 64 words input, 64 words output. However, for systems with a large number of discrete systems, the use of expansion modules can greatly increase the number of discrete points, eliminating the need for remote I/O (RIO) substations. For example, without an expansion module, a 16-slot rack such as a 32-point discrete module can have up to 14X32=448 discrete I/Os. After adding an expansion module, two 16-rack systems can have up to 13X32. +14X32=864 discrete I/Os. Therefore, for systems with a large amount of discreteness, such as local I/O racks, it is not enough. Consider using expansion modules. 10: What should I pay attention to when configuring Quantum and Premium, Micro? When configuring Quantum, you must be aware that the maximum number of I/O words that the local CPU can carry is 64 words and 64 words. This word limit includes discrete and analog quantities. For discrete I/O, 16 points is a word. The number of words corresponding to the analog I/O can be found on the sample or when configured with Concept. The sum of the bus currents required for all modules must be less than the current supplied by the power supply template. When Premium, Micro is configured, the maximum number of discrete and analog quantities depends on the CPU used and can be found in the product samples. Note that the MicroTSX3721 and TSX3722 can be equipped with up to 5 blocks with a 28-point I/O module; for example, a high-density module with 64 points can be used with up to three. 11: How do I calculate the maximum distance between a Quantum I/O template and a field device? The maximum distance between a Quantum I/O template and a field device can be calculated by the following formula: X=(Uin–Uonmin)∕(Ionmin*2*Swire) X: Maximum distance between Quantum I/O template and field device Uin: Input loop voltage value Uonmin: Minimum voltage value when input is ON Ionmin: Minimum current value when input is ON Swire: Attenuation of signal line (unit: ohm ∕米) 12: What is the maximum period of memory data storage by the battery when the QUANTUM series CPU is in the power-down state? 140CPU11302 454 days 140CPU11303 238 days 140CPU43412X 238 days 140CPU53414X 119 days 13: Is there a terminating resistor in the Interbus-S network? There is no terminating resistor. The Interbus-S network is an RS485 network, and the terminating resistor is implemented by the last slave in the network. There are two connectors on the Interbus slave. The connector on the top left is connected to the network. The connector on the top right has two functions. One function is to connect other slaves to the Interbus network. The other function is Terminate the network. This connector has a built-in microswitch. If a cable is connected to this connector, this microswitch opens the terminating resistor. If the cable is not connected, this microswitch will connect the terminating resistor to the network. 14: Redundancy in Quantum How to calculate the total system floor load in the remaining power system? If there are N redundant power supplies in the Quantum rack, the total system backplane load is less than or equal to (N-1) power capacity, for example: If mounted on the backplane With 2 8A redundant power supplies, the maximum backplane load is (2-1)*8=8A. If three 8A redundant power supplies are installed on the backplane, the maximum backplane load is (3-1 ) *8=16A 15: Can the Quantum dual-system hot standby system automatically switch when there is a problem with MB+ or Ethernet? No. The Quantum dual-system hot standby system can only switch automatically in the following four cases: Main frame Power failure Main frame CPU failure Main frame RIO adapter failure Main frame RIO link failure 16: Does Quantum also have hot start and cold start? Yes, Quantum also has hot start and cold start points. The first time after completely downloading a project The start is a cold start, and any other start is hot start. For example, the PLC is powered on again or the PLC is hot start from stop to run. 17: Can you install two different accumulates on one bottom plate of Quantum? Power? Yes, for example, 140CPS11410 and 140CPS11420 can be mounted on a backplane, the accumulated current is calculated with a small current, the current of the 140CPS11410 is 8A, and the current of the 140CPS11420 is 11A, so the total accumulated current is 16A. 18: In the quantum dual machine In a hot standby system, can I upgrade the firmware without stopping the hot standby operation? can. The 12th bit in the Hot Standby System Command Register must be set. This way, you can upgrade the firmware without stopping the application.
They are different from traditional cigarettes and work by heating tobacco to a very low temperature. Tobacco is heated to 350 ° C in a heat-incombustible device, while traditional cigarettes burn at up to 900 ° C.
Still, the temperature at which non-combustion products are heated is high enough to vaporize and inhale harmful chemicals.
Although both are electronic devices, heated non-combustible products are also different from e-cigarettes or steam devices. These usually use chemical liquids and do not necessarily contain nicotine. E-cigarettes tend to heat liquids to around 250 degrees Celsius to produce vapor.
