The QJ71NT11B is a MELSECNET/H Network Module manufactured by Mitsubishi Electric. It is a communication module designed for use in industrial automation systems to enable networking and data exchange between devices. The module operates using a twisted bus-type network, where devices are connected in a daisy-chain fashion using twisted pair cables. It supports the MASTER/LOCAL configuration, allowing for centralized control and distributed devices. The communication speed can be set to various settings ranging from 156 kbps to 10 Mbps, providing flexibility based on the specific application requirements. The communication method used is a token bus method which facilitates efficient and reliable data transfer. The QJ71NT11B module also uses a frame synchronous method for ensuring that data is transmitted in a synchronized manner across the network. It utilizes an RS-485 bus transmission path format. The module supports a maximum of 239 networks and 32 groups, allowing for the creation of large-scale network architectures. For connectivity, the module requires twisted pair cables, which can be either standard twisted pair cables or the Version 1.10 compatible CC-Link dedicated cables. It operates with 32 I/O occupied points. The internal current consumption of the module is 0.6A at 5V DC. The external dimensions of the module are 98mm (height) x 27.4mm (width) x 90mm (depth). The module can handle up to 32 stations per network, with 1 control station and 31 normal stations. This allows for flexible network configurations and communication between multiple devices within the network. The QJ71NT11B network module requires 2-core twisted pair cables.
