Example Scenario 2.10
Accessing data from an electronic meter via a GSM data call (Iberdrola, Endesa, etc.) and via GPRS,
giving priority to the GSM call made by the company. Also, obtaining remote access to a network
analyzer using an Ethernet port via Modbus TCP
.
Details of the example scenario:
We need to provide Internet access to a network analyzer with an Ethernet interface. We must
be able to access it in the TCP502 port given that it is a Modbus TCP meter. The meter’s LAN
IP address is 192.168.1.70.
On the other hand, we have an electricity meter with an RS232 port with the configuration
9600bps 8N1. The data from this meter should be accessed using a transparent GPRS-
RS232 gateway, for which we will use the TCP20010 port.
The energy provider (Iberdrola, Endesa, etc.) must also be able to access the electricity meter
via a typical GSM (CSD) data call. When the operator access the data, the GPRS connection
will be suspended until the call is terminated.
