5. Set M101.0 in the CPU to TRUE.ð The Modbus request is sent and it is waited for a response.If M101.0 is automatically reset, the job was finished without errors and the readdata are stored in the CPU starting from bit memory byte 200. MW108 returns7004h and indicates waiting for a new job.If M101.0 is not automatically reset and MW108 returns non-zero, an error hasoccurred. The cause of error can be read by the code of MW108 (e.g. MW108 =8382h when the start address 2000 in the server is not available). MW108returns 7004h and indicates waiting for a new job.9.1.2 FB 71 - TCP_MB_SERVER - Modbus/TCP server9.1.2.1 DescriptionThis function allows the operation of an Ethernet interface as Modbus/TCP server.Call parameterName Declara-tionType DescriptionENABLE IN BOOL Activation/Deactivation Modbus server.MB_DATA_PTR IN ANY Modbus: Data buffer (only flag area or data block oftype Byte allowed) for access with function code 03h,06h and 10h.ID IN WORD ID from TCON.NDR* OUT BOOL New data were written by the Modbus client.DR* OUT BOOL Data were read by the Modbus client.ERROR* OUT BOOL Job is ready with error - parameter STATUS haserror information.STATUS* OUT WORD Extended status and error information.*) Parameter is available until the next call of the FBParameter in instance DBName Declara-tionType DescriptionREQUEST_COUNT STAT WORD Counter for each received frame.MESSAGE_COUNT STAT WORD Counter for each valid Modbus request.XMT_RCV_COUNT STAT WORD Counter for each received frame, which contains novalid Modbus request.EXCEPTION_COUNT STAT WORD Counter for each negatively acknowledged Modbusrequest.SUCCESS_COUNT STAT WORD Counter for each positively acknowledged Modbusrequest.FC1_ADDR_OUTPUT_START STAT WORD Modbus Function code 01h start register for Q0.0Default: 0VIPA SPEED7Modbus CommunicationTCP > FB 71 - TCP_MB_SERVER - Modbus/TCP serverHB00 | OPL_SP7 | Operation list | en | 18-30186
