Item Description Default
Char Timeout (bytes)
Modbus RTU requires 3.5 char time between messages.
This parameter is used to set the waiting time (based on bytes) that
should elapse after last byte of data of the response is received from
the slave device is activated. If no more data is received before the
timeout period expires, then the transmission of this packet is
deemed to have been completed and the IS-MS3180 begins
processing the packet.
Valid range: 4 to 15 (bytes);
4
Silent Time (ms)
This parameter is used to set the idle time that should elapse before
sending each request to the serial port. This causes the serial bus to
be "silent" for the specified period and allows slower slave devices
more time to process previous requests and responses, thereby
reducing communication problems.
Valid range: 10, 20to 65530 (ms);
0
Read Cache (ms)
When sharing Modbus RTU/ASCII device/data between several
master devices, the read-cache function can be used to reduce the
loading on the serial communication and ensure faster TCP
responses.
Valid range: 10, 20to 65530 (ms); Disable = 0.
980
Local TCP Port
This parameter is used to configure the Modbus TCP port.
Note: The default COM1/COM2/COM3 = TCP Ports 502/503/504.
502
Connection Idle (seconds)
If Modbus TCP communication is idle for a specified period of time,
the system will automatically terminate the connection.
Valid range: 1to 65535 (seconds); Disable= 0;
180
Protocol
This parameter is used to configure the serial port that’s used by the
Modbus RTU or Modbus ASCII protocol.
