Radioline EMpro Modbus communication2 Configuration of Radioline2.1 System setupPoint-to-PointM MasterStarS SlaveLine/MeshR RepeaterPoint-to-Point/StarA point-to-point/star network may consist of only one master and up to 249 slaves. In this network structure, each slave isdirectly connected to the master. The data exchange in this structure can be very fast. The more slaves are in the network,the higher is the delay time of the radio network.Line/MeshA mesh network may consist of only one master and up to 249 slaves. A mesh network supports repeater functionality, it isable to heal itself. If a connection is lost, the device can establish an alternative communication path. This construction ofan alternative communication path is done automatically within a very short time. This time depends on the data rate of theradio interface. The network type “line/mesh” results in a longer delay, because in this setting each wireless module worksas a repeater/slave. The delay time depends on the number of repeaters/slaves in the network and of the selected datarate of the radio interface (16/125/250 kbaud).The Radioline devices support the following functions:Master: The master wireless module is the central point in the network. Initializations and network-specific functions arecoordinated by the master. Without a master, there is no wireless connection in the network. The master of a wirelessnetwork is usually located at a central point, for example in the control room. The master PLC, which is connected to themaster wireless module, manages the serial data transmission. There can only be one master in the network. The masteralways has the RAD-ID 01.Slave: Slaves always build the endpoint of the network and cannot forward data to other slaves. Slaves of a PLC can beconnected to a slave wireless module. Slave wireless modules only have subordinate rights.Repeater/Slave: A repeater/slave can communicate data to other wireless modules in the network. It is possible to buildline/mesh structures. A repeater/slave supports two functions: The wireless module works as a repeater by receiving andforwarding data and as a slave by sending the data to its serial interface. A slave PLC can be connected to eachrepeater/slave wireless module.QRG 605 EN 00 RAD-2400-IFS EMpro-Modbus.docx PHOENIX CONTACT11

Step 1: Select the network type ”Point to Point / Star“ and confirm with ”Next“.Note:Selecting the network type ”Line/Mesh“ results in a longer delay, as in this setting each wireless module works as arepeater/slave. The delay time depends on the number of repeaters/slaves in the network, the data package size and theselected data rate (16 / 125 / 250 kbaud).5.
