12/06 AWB2724-1584GB 17 The easy-NET network Overview Sending/receiving user data easy-NET is based on the CAN network that enables the exchange of process and system data. This network is designed for 8 stations (PLCs). Each station is assigned an ID number 1…8 and can exchange data with all other stations. Bit, byte, word and double word data formats are available. The station with ID1 must always be present. This is responsible for managing the communication in the network.
12/06 AWB2724-1584GB The easy-NET network From the user program to the protocol task: Data transfer options • Send user data via the easy-NET – Local and extended outputs (byQ/byS) – Local and extended inputs (wI/wR) – Send data to a selected station X (aToID[x].dwSN) – Set local outputs of stations without own program (aToID[x].byQ/aToID[x].byS ). This operation is only possible from NET-ID1. – Send data with the PUT command (Broadcast).
12/06 AWB2724-1584GB Overview Transfer of bit data blocks between several PLCs Each PLC can send a 32-bit data block to another specified PLC via the easy_NET. To do this, call the NET_UPDATE function in the program of the EC4-200 PLC and enter the station number X of the receiver via the structure (EASY_NET_MAIN) (SND.aToID[X].dwSN). Write the data to be sent to the variable dwSN. To receive data from other PLCs, use the structure (EASY_NET_MAIN).
12/06 AWB2724-1584GB The easy-NET network 1st connection: The value “a” (32-bit) is transferred from EC4-200 (ID1) to the easy800 (ID2). The following structure must be programmed in the EC4-200: NET_MAIN.SND.aToID[2].dwSN:=a; The value can be processed in the easy800 by the scanning of the input bits 1RN1 to 1RN32. 2nd connection: A data block with the value 7 (3hex) has to be sent from the easy800 PLC (ID3) to the EC4-200 (ID1). The 3 outputs 1SN1, 1SN2, 1SN3 must be programmed and set in the easy800.
12/06 AWB2724-1584GB Configuring EC4-200 with easy800 on the easy-NET The EC4-200 scans this data unit. For this the following structure variable entries are required: (EASY_NET_GET).byModuleNumber := 2; (EASY_NET_GET).byNET_ID := 3; Figure: 106: Transfer of data according to the PUT-GET principle Figure: 108: Transfer of data according to the PUT-GET principle (GET) The following program sequence can be used in the EC4-200 in order to execute a PUT operation.

12/06 AWB2724-1584GB Programming via easy-NET (Routing) Routing offers an advantage which makes it possible to access all routing capable PLCs on the easy-NET bus from any PLC which is connected with the programming device. This makes it possible to operate remotely configured controllers easily. However, the data transfer rate with routing connections is considerably slower than with direct connections (serial or TCP/IP).
12/06 AWB2724-1584GB The easy-NET network Bus topology A bus topology can be configured as a linear topology with optional spur lines. The ends of the bus must be terminated by bus terminating resistors (120 Ohm). figure 115 shows two connection options.
