RS485 cable transmission distance: 24 awg RS - 485 cable (wire diameter of 0.51 mm), for example, when the data signal rate dropped to below 90 kbit/S, assuming maximum allowable signal loss is 6 DBV, the cable length is limited to 1200 m, when the signal data rate of 600 kbit/S, using 24 awg cable, maximum cable length is 200 m, if using 19 awg cable (wire diameter of 0.91 mm) cable degrees will be able to more than 200 m long; If 28AWG cable is used (line diameter is 0.32mm), the cable length can only be less than 200m.
PLC作为主站,使用软件Modsim32模拟从站,使用两芯线(**是带屏蔽双绞线)进行连接:硬件连接将通讯板的AB两端与转换器的AB两端进行连接,要注意AB两端区分正负极,反接不会烧坏设备,但是无法正常通讯。编写程序1.设备组态在博图软件中配置西门子PLC和通讯板。modbus通讯需要设置波特率、数据位、停止位和校验位等通讯参数,在博图中的设备组态中设置此参数,主从站设置一致即可通讯。通讯参数设置波特率9600,数据位8位,停止位1位,无校验,在PLC离线模式下下载硬件组态。
自承式全塑电缆(HYAC):自承式全塑电缆有同心式结构和葫芦型结构两种,常用的HYAC型自承式全塑电缆为葫芦型结构。导线:退火裸铜线,直径为、0.4、0.5、0.6、0.7、0.8、0.9;按照全色谱标准标明绝缘线的颜色。
说的通俗些铠装电缆也就是地埋的电线电缆,动力线传输电能电缆加上铠装层的目的除了增强抗拉强度、抗压强度等机械保护延长使用寿命外,铠装的有一定的抗外力性能,还可以放一些老鼠撕咬,不至于透过铠装造成电力传输问题,铠装的弯曲半径要大,铠装层可以接地保护电缆动力铠装电缆:型号有:VV22、VVR22、VVP2。
Solid insulated filled cables are suitable for urban and township telecommunication lines of local telecommunication networks and for special network lines connected to public networks. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shield layer are filled with oil paste and poured to prevent water intrusion. The mechanical and electrical properties of the cable remain unchanged under conditions of 30~C - 60~C.

This product is suitable for electronic computers with rated voltage of 500V or below, and cables for automatic connection, which have high re for protection. The k-type B low-density polymer with anti-oxidation property is adopted for the insulation of cable ground core. High insulation resistance, good voltage resistance, low dielectric coefficient and low dielectric loss temperature and variation of the medium can not only meet the re of transmission performance, but also ensure the service life of the cable. ? The cable is shielded for cross - circuit interference and external. The shielding re of cables are respectively adopted according to different conditions: the total shielding of the hinged cable, the total shielding of the hinged cable, and the total shielding of the hinged cable after the hinged cable is shielded. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. The insulating property of shielding pair and shielding pair. The transmission of the cable will not be affected if there is potential difference between shielding pair and shielding pair in use.
.1、产品名称:铠装双绞屏蔽线RVSP222、产品介绍:RVSP系列在RVS的基础上再加上一层铜丝屏蔽网,因此在减少信号的传输损耗、屏蔽外界干扰方面比RVS系列效果更好,但由于增加了铜丝屏蔽网,它的成本也比RVS系列高出许多。
