The TCP notification client can establish connections with a remote Modbus/TCP server and send notification messages either on events, or periodically on a time basis. Notification messages are sent via a block of 16 Modbus registers using write function 16. The server’s IP address, port number and starting Modbus register address are programmable in the meter.
Client connections are triggered via programmable setpoints, which are configured to respond to desired triggers or to periodic time events. After receiving a write acknowledgement from a server, a TCP connection is still open for 10 seconds (20 seconds via GPRS) to give the server an opportunity to access meter registers through an open socket.
