Parameter Value Description
Float Flag
(Enron-Daniels) Yes or No Specifies if the floating-point data access functionality is
active.
Y
ES
- Modbus functions 3, 6, and 16 interpret floating-point
values for registers as specified by Float Start and Float
Offset .
N
O
- The gateway does not use floating point functionality.
Float Start 0 to 65535 This parameter only appears if Float Flag is Yes.
Specifies the first register of floating-point data if Float Flag
is Yes. All requests with register values greater than or
equal to this value are considered floating-point data
requests. For example, if you enter 7000, the gateway
considers all requests for registers 7000 and above as
floating-point data.
Float Offset 0 to 3999 This parameter only appears if Float Flag is Yes.
Specifies the start register for floating-point data in the
internal database. For example, if you enter 3000 and set
Float Start to 7000, data requests for register 7000 will use
the internal Modbus register 3000.
Output Offset 0 to 3999 This parameter applies if the port is configured as a slave.
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
you set this parameter to 50 and the gateway receives a
Function Code 1 command requesting Coil address 0
(virtual Modbus Coil address 00001 or 000001), the
gateway returns the value at register 50, bit 0 in the
gateway's database.
Bit Input Offset 0 to 3999 Specifies the offset address in the internal Modbus
database for network requests for Modbus function 2
commands. For example, if you set this value to 150, an
address request of 0 returns the value at register 150 in the
database.
Holding Register Offset 0 to 3999 Specifies the offset address in the internal Modbus
database for network requests for Modbus functions 3, 6, or
16 commands. For example, if you set this value to 50, an
address request of 0 returns the value at register 50 in the
database.
Word Input Offset 0 to 3999 Specifies the offset address in the internal Modbus
database for network requests for Modbus function 4
commands. For example, if you set the value to 150, an
address request of 0 returns the value at register 150 in the
database.
Connection Timeout 0 to 1200 Specifies the number of seconds the server waits to receive
new data. If the server does not receive any new data
during this time, it closes the connection.
