Re: SBL2e dividing serial messages on TCP

Do you think it minimizes network traffic by splitting packets? It needs much more ballast around the message. The packets on TCP have it's own numbers. I can't imagine how the packets could be split somewhere on the way. But I understand they can be splitted and depends on the FW of producer how it...

Re: SBL2e dividing serial messages on TCP

Probably some devices can split TCP packets, but if there is possibility of custom packetization in SPL2e, there is no reason why it shouldn't work. The SPL2e splits the packets even if it is connected directly to computer and there is no other communication. You can see the split of the packet in f...

Re: SBL2e dividing serial messages on TCP

I'm going to send you a picture of serial massage from osciloscope, a data from serial terminal and a data from wireshark tomorrow. You'll see. It happens irregularly (ones per 15s) and it seems to be dependent on quantity of other TCP communication (it's only theory). We use the release number 1.65...

Re: SBL2e dividing serial messages on TCP

Thanks for the answer, bud it didn't satisfy me. First - as I wrote in my first post I have serial messages of max length 50 char. It takes 50x512us=25,6ms. I've set number of accumulated char. 512, for sure to flush whole message in one packet. Second - I tried to find what exactly means the time &...

Re: SBL2e dividing serial messages on TCP

I understand the dividig of packets is not a fault but a feature. But unpleasant feature. If some feature is named: custom packetization, I'd suppose it'll create packet according to its setting. We are able to complete messages in our SW, but we have to explain it to our customers and to explain wh...

Re: SBL2e dividing serial messages on TCP

Thanks for the answer. I supposed it. The problem is, that Modbus protocol isn't ASCII and doesn't use start and stop characters. But I have already solved it in SW. I only hoped that custom packetization helps me. For monitoring of ethernet communication I use wireshark. It is very sophisticated pr...

SBL2e dividing serial messages on TCP

I use the chip SBL2e for serial to TCP converter. I'd like to make the converter to send all serial data in one TCP packet. Protocol is Modbus TCP - my PC is a Master, the serial device behind converter is a Slave. Maximal length of my serial messages is 50 characters. Characters are sent without sp...
