2.3.4 Output Offset
0 TO 3999
When the port is configured as a slave, this parameter specifies the internal
database address to use as the zero address or starting point for binary output
Coil data. Coil data is read by Modbus Function Code 1 commands (Read Coils)
and written by Function Codes 5 (Force Single Coil) or Function Code 15 (Force
Multiple Coils). For example, if this parameter is set to 50 and a Function Code 1
command is received requesting Coil address 0 (virtual Modbus Coil address
00001 or 000001), the data returned in the response will be the value at register
50, bit 0 in the gateway's database.
2.3.5 Bit Input Offset
0 to 3999
This parameter specifies the offset address in the internal Modbus database for
network requests for Modbus function 2 commands. For example, if the value is
set to 150, an address request of 0 will return the value at register 150 in the
database.
2.3.6 Holding Register Offset
0 to 4999
This parameter specifies the offset address in the internal Modbus database to
with network requests for Modbus functions 3, 6, or 16 commands. For example,
if the value is set to 50, an address request of 0 will return the value at register
50 in the database.
2.3.7 Word Input Offset
0 to 3999
This parameter specifies the offset address in the internal Modbus database for
network requests for Modbus function 4 commands. For example, if the value is
set to 150, an address request of 0 will return the value at register 150 in the
database.
2.3.8 Connection Timeout
0 to 1200 seconds.
This is the number of seconds the Server will wait to receive new data. If the
Server does not receive any new data during this time, it will close the
connection.
