5.2 Modem PAD Configuration for a SCADA Master Device Polling a Single

Field Device in Slave Mode

In this example, a Chameleon modem is connected to a master device which polls data from a single field

device in slave mode. The field slave device is either connected to another Chameleon modem or has

built-in TCP/IP functionality. The master device is typically a server running a SCADA application and

communicates with the field device via a request/response protocol. The slave devices will only send

responses to requests sent.

The modem connected to a master device operates at a baud rate of 19200 with full hardware flow

control. The master device receives sentences on its serial port of maximum length 100 bytes (with no

common end character) which are to be sent to a single slave unit at IP address 100.100.1.2, port 5000.

The serial master device requires echoing of data that it sends to modem.

For the modem connected to the serial master device, enter the following commands from the serial

console:

cmd factory

cmd mode 4

1 2 ... 6 7 8 9 10 11 12 13 14 15
