Dear Sir/madam, We haveS7-412 PLC CPU standalone system having 2 ethernet CP 443-1. Now we are trying to establish communication with remote siemens PLC through firewall gateway. We have created new TCP connection in netpro of SIMATIC manager. Please refer attached TCP connection configuration setting screen shots. After offline setting in netpro, we tried to download the TCP connection in PLC by clicking connections and gateway option in netpro (Please refer screen shot). but we could not able to download due to below message. Please refer screen shot as well for below message pop up. " The system data can not be loaded to module (RO/S3) of station." Look under details or try to determine the cause for the problem using the diagnostic buffer of the module" PLC CPU diagnostic buffer is showing below events. Plz refer screen shot for dia. buffer. "parameter assignment error assigning parameters to modules (not on P bus, cancel download) no relevance for user: SDB number 1006.Error type: protocol error or negative acknowledgement for labeling a block." Please advice to resolve this TCP connection download issue. If you need more info on this topic please feel free to contact us. Appreciate your prompt response on this. Thank in advance.
