CC-Link是一种高可靠性、高性能的网络。
CC-Link的优势如下:
1) 高速度大容量的数据传送可设定介于156Kbps到10Mbps间可选择的5种通信速度之一。
总长度由最大通信速度决定。
每个循环传送数据为24字节,有150字节用于通信传送。
8字节(64位)用于位数据传送,16字节(4点RWr、4点RWw)用于字传送,
(L=>M 34字节)。
每次链接扫描的最大容量是2048位和512字。
在64个远程I/O站的情况下,链接扫描时间为3.7毫秒。
稳定快速的通信速度是CC-Link的最大优势。
CC-Link有足够卓越的性能应用于大范围的系统。
当应用10Mbps的通信速度时,最大通信距离是100米;当通信速度为156Kbps时,最大通信距离为1200米。
如果应用中继器,还可以扩展网络的总长度。通信电缆的长度可以延长到13.2KM。
2)拓扑结构有多点接入、T型分支、星型结构
3种型号的电缆及连接器可以支持将CC-Link元件接入任何机器和系统。
3)CC-Link使分布控制成为现实
CC-Link同样用于低价的中间控制层网络。
所有的本地站和智能站可以访问循环数据,如到达从站或来自从站的RX、RY、
RWr、RWw。(但不可改变这些数据)
如果使用这些循环数据,可以保证高速的应答和稳定的刷新时间,使中间控制通信、中央控制系统变成现实。
有些应用中要求有控制层和元件层2种网络,这样的系统可以仅仅只用CC-Link。
由于CC-Link每个站有固定的循环数据的范围,可能使循环数据受到限制,但,它毕竟是一个低价的网络。
