  • Page 16: Configuration Of Network Basic Parameters Through The Console

    Introduction Introduction The SSE232-IA maps each COM (A, B, C or D) to a communication socket. Thus, once socket connection is established, information will be transparently transferred from the corresponding COM to the socket and vice versa, as depicted in Figure 10.
  • Page 17 1002 and 1003 are mapped to COM A, B, C and D respectively, but this may be changed for each COM. As it can be observed in Figure 10, the SSE232-IA has also 3 fixed TCP ports: Supervision and Control (Port 999), Configuration Command Console (Port 998) and HTTP Server (Port 80).

  • Page 19 Enabling and Disabling Web Configuration Enabling and Disabling Web Configuration The administrator may enable or disable SSE232-IA Web page configuration. Once disabled, the administrator will only be able to access the configuration remotely through the TCP command console or, locally, by the serial command console. In both cases, the administrator will be able to re-enable Web configuration.

    That is, the SSE232-IA will abort the previous connection, allowing the new client to connect. If the automatic reset is not enabled for that server channel, the SSE232-IA will deny the newer connection. Note that in this case, the server may still use the inactivity timeout feature.

  • Page 26: Supervision And Control Port

    Supervision and Control Port. Supervision and Control Port. The SSE232-IA allows to control digital inputs/outputs and to supervise the status of connection sockets linked to every channel by simple commands. The Supervision and Control Port works through a TCP connection in the port 999. Each command must end with the CR character (ASCII 13).
  • Page 27 The INA command shows the status of all available inputs in each SSE232-IA model. The IN command allows to know the status of one of the available inputs in each SSE232-IA model. If you request an unavailable input, the answer will be “error”.
  • Page 28 If the automatic digital input report option is enabled, SSE232-IA will inform the status of all the inputs when a client connects to the TCP Port 999 and every time a change in any of the available inputs is detected.

  • Page 29: Udp Transport Protocol Udp Transport Protocol

    SSE232-IA User’s Manual Exemys If the Automatic Digital Inputs Report is enabled, the SSE232-IA will inform the status of the inputs through the message DIR in the Supervision and Control Port (TCP Port 999). The client of this connection will not have to execute any command for the SSE232-IA to send this message.

  • Page 30: Client Channel With Udp Protocol

    If the IP server address of that channel coincides with the broadcast address (IPSERV = 255.255.255.255), SSE232-IA will transmit serial data as a UDP broadcast. The serial will transmit whatever is received from the Ethernet side, no matter if data was delivered using the broadcast address or a specified IP address.

  • Page 31: Connection Between Two Udp Clients

    When two SSE232-IA connect through an UDP Transport Protocol, one of them in Client Mode and the other in Server Mode, the SSE232-IA device running in Server mode will not send any serial data to the Client’s IP unless the client has previously sent a packet to establish communication.
