Dear All I have configured the PAC3200 in S7-414H CPU in netpro, keeping S7 as client. The config was done as per the Modbus Redundant TCP manual. In CP0 - the remote port address was given as 502 and the local address was given as 2000. In CP1 - the remote port address was given as 503 and the local address was given as 2000. The MODB4H block was configured for client and the parameters are loaded in OB100 and OB1 as per the example program. The net pro config was downloaded to CPU. The IP address (192.168.0.42) was set to the powermeter and MODBUS TCP protocol is selected as per the manual. When the ENQ_ENR signal was given, the FB shows the active CP and gives an error code A008 and the error bit is set. Error A008 - Monitoring time MONITOR elapsed; connection is not established; partner is not ready. When I diagnose the CP, it connects to the powermeter (IP address) and shows the message sent successfully. But there is no data received from the powermeter. Can anybody help me in this regard? The screen shot is uploaded. Thanks in advance. Regards, Kanag AttachmentModbus TCp Error.zip (895 Downloads) |

Hello Kanag, did you change the protocol at PAC3200 to Modbus? The standard configuration is SEAbus protocol. Regards, Kaulquappe |

Hi Kanag, Are you using one Switch for all devices connect to Ethernet? If you have more than one, let's move all devices to one Switch. TuanNA. |

Hello Kanag, PAC3200 can only use port 502 for Modbus communication. Regards, Kaulquappe |
