Description
10,052
Minimum Response
Time
This parameter specifies the minimum number of
milliseconds to delay before responding to a
request message. This pre-send delay is applied
before the RTS on time. This may be required
when communicating with slow devices.
10,053
Use CTS Line
This parameter specifies if the CTS modem control
line is to be used. If the parameter is set to 0, the
CTS line will not be monitored. If the parameter is
set to 1, the CTS line will be monitored and must
be high before the module will send data. This
parameter is normally only required when half-
duplex modems are used for communication (2-
wire).
10,054
Slave ID
This parameter defines the virtual Modbus Slave
address for the internal database. All requests
received by the port with this address are
processed by the module. Verify that each device
has a unique address on a network. Valid range for
this parameter is 1 to 255 (247 on some networks).
10,055
Bit in Offset
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.
10,056
Word in Offset
This parameter specifies the offset address in the
internal Modbus database for network request 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.
10,057
Out in Offset
This parameter specifies the offset address in the
internal Modbus database for network requests for
Modbus function 1, 5, or 15 commands. For
example, if the value is set to 100, an address
request of 0 will correspond to register 100 in the
database.
10,058
Holding Reg Offset
This parameter specifies the offset address in the
internal Modbus database for network requests for
Modbus function 3, 6, or 16 commands. For
example, if a value of 50 is entered, a request for
address 0 will correspond to the register 50 in the
database.
10,059
Command Count
This parameter specifies the number of commands
to be processed by the Modbus Master Port.
10,060
Minimum Command
Delay
This parameter specifies the number of
milliseconds to wait between issuing each
command. This delay value is not applied to
retries.
10,061
Command Error Pointer
This parameter sets the address in the internal
Modbus database where the command error will be
placed. If the value is set to -1, the data will not be
transferred to the database. The valid range of
values for this parameter is -1 to 9675.
