Hi. Problem is a bug in OpenDHCPServer.cpp. It exists when OpenDHCPServer is run in the console using the "-v" argument. I guess void procHTTP(data19 *req) { ... if (verbatim || cfig.dhcpLogLevel >= 1 && (errno || req->bytes <= 0)) { sprintf(logBuff, "HTTP Client %s, Message Receive failed, WSAError %d", IP2String(tempbuff, req->remote.sin_addr.s_addr), errno); ... } should be void procHTTP(data19 *req) { ... if ((verbatim || cfig.dhcpLogLevel >= 1) && (errno || req->bytes <= 0)) { sprintf(logBuff,...
The documentation is misleading. There's a maximum of 32 [RANGE_SET] groups. But each [RANGE_SET] group can have multiple DHCPRange=... lines. And the maximum of all DHCPRange=... lines (over all [RANGE_SET] groups) is 125. Regards Max

Hi, I know this is an old topic, but I'm still struggling with it. Not only with WinCC but also when trying to use a "variable observation table" (don't know the exact English name for it) in SIMATIC Manager. Both use cases are - of course - noted as not implemented on the Snap7 Server page: Cyclic data I/O The server does not replies at all. As far as I have understood the information given by the WinCC help, the PLC could always deny the request to use the cyclic read methods. Wouldn't it be a...

Huh. This is an improvement I would really appreciate. But 11 years without any progress?...
