Modbus Converter Server Mode - Planet ICS-2102ST User Manual

4.5.2.9 Modbus Converter Server mode

The ICS Serial devices support standard Modbus protocol and various hardware interfaces (serial and Ethernet). Modbus TCP
and RTU can be used to convert the Modbus protocol. The Modbus master can communicate with the serial network of devices
connected to the serial port of the server converter via a server converter.
The meter receives Modbus TCP / IP data on TCP port 502, translates it to a Modbus RTU, and then forwards it to the
addressed slave device.
Functionally allows monitoring software to access information from slaves for trend analysis, data collection, alarm/event
management, maintenance and other functions. The Modbus Converter Server mode topology in

Description
TCP keep alive interval shows how many seconds the unit waits during an inactive
connection before checking its status. If the unit does not receive a response, it will drop
that connection. The default is 0 minute.
When the network connection is determined to be idle, the duration of the control
network inactivity will cause the connection to be forced closed.
The default value is 0.
This parameter set the TCP port number on which it will listen for the connection and set
the maximum (up to two) acceptable number of connections. The range of value is from
1 to 4. The default is 1.
Scope: 1 to 65535. Default: 5004 for port 1, 5005 for port 2 and so forth.
This parameter is described the TCP port that communicates with the connected device.
The setting slave and master destination IP parameters must use the same value to
appears.
