    • An industrial process control system (10) comprises a process control device (12), a first wireless communication network (11), a second wxreless communication network (27) and a first group of wireless field devices (16, 18, 20, 22, 24, 26) interfacing the industrial process and being associated with the first network. The network supervisor device investigates if the field devices of the first group are able to communicate with the process control device via the first network while meeting a communication restriction requirement (ΔT), and redirects, in case the requirement is not met, communication between some of the field devices in the first group and the process control device to the second network so that the requirement is met for a first part (16, 18, 20) of the field devices using the first wireless communication network and for a second part (22, 24, 26) of the field devices using the second wireless communication network.
    • 一种工业过程控制系统,包括过程控制设备,第一无线通信网络,第二无线通信网络和与工业过程接口并与第一网络相关联的第一组无线现场设备。 网络监控设备检查第一组的现场设备是否能够在满足通信限制要求的情况下通过第一网络与过程控制设备进行通信,并且在不满足要求的情况下重定向一些现场的通信 第一组中的设备和到第二网络的过程控制设备,使得使用第一无线通信网络的现场设备的第一部分和使用第二无线通信网络的现场设备的第二部分满足要求。
