Hello, I am making the project, where gateway with UDP packet forwarder, connected to PLC. The gateway sends the data each minute using UDP to PLC controller, so gateway is initializer of communication. I looked up on OSCAT net library, but this does not suits me, since two blocks are required on both PLC to use UDP.
Does someone has a project utilizing UDP communication, which can be used for PLC and gateway communication ?
Try IP_CONTROL instead of NET_VAR_CONTROL
Thank you for advise. Will try.
Checked the block, may be I have stupid question but how to enable the block, choose read/write option and how to select UDP ? I see in VAR list it is possible to select UDP option, but it internal variables, cant modify them.
Sorry for many questions, can it be that this library suits only for limited PLC's, like plc 841 ? Meaning not all PLC are supported by OSCAT network library.
