为了构建 PROFIBUS DP 网络,提供有不同类型的电缆,可满足不同类型应用的要求。一般地,应该使用所列出的电缆。有关网络组态的详细信息,请参见 PROFIBUS 网络手册。
UL 认证
用于网络电缆的 UL 列表(安全标准)对于美国和加拿大市场尤为必需。根据电缆敷设在建筑物中位置来决定适当的认证要求。这适用所有电缆,这些电缆从一个机器敷设到一远程控制柜,位于电缆架上并保护着建筑物。通过 UL 认证的电缆在其名称后面附加字母“GP”(通用)。
Ex认证
用于本质安全 PROFIBUS DP 应用的电缆在其名称后面附加字母“IS”(本质安全)

电缆类型
全新的快速连接(FC)总线电缆为径向对称设计,可使用剥线工具。以此,可以快速、简便地安装总线接头。
