Register Content Description
10,005 Error Status Pointer This parameter specifies the register location in the
module's database where module status data will
be stored. If a value less than zero is entered, the
data will not be stored in the database. If the value
specified in the range of 0 to 9940, the data will be
placed in the user data area.
10,006 to 10,009 Spare
6.5.2 Port 1 Setup
Register Content Description
10,010 Enable This parameter defines if this Modbus Port will be
used. If the parameter is set to 0, the port is
disabled. A value of 1 enables the port.
10,011 Type This parameter specifies if the port will emulate a
Modbus Master device (0), a Modbus Slave device
without pass-through (1), a Modbus Slave device
with unformatted pass-through (2), a Modbus Slave
device with formatted pass-through and data
swapping (3), or a Modbus Slave device with
formatted pass-through and no data swapping (4).
10,012 Float Flag This flag specifies if the floating-point data access
functionality is to be implemented. If the float flag is
set to 1, Modbus functions 3, 6, and 16 will
interpret floating-point values for registers as
specified by the two following parameters.
10,013 Float Start This parameter defines the first register of floating-
point data. All requests with register values greater
than or equal to this value will be considered
floating-point data requests. This parameter is only
used if the Float Flag is enabled.
10,014 Float Offset This parameter defines the start register for
floating-point data in the internal database. This
parameter is only used if the Float Flag is enabled.
10,015 Protocol This parameter specifies the Modbus protocol to be
used on the port. Valid protocols are: 0 = Modbus
RTU and 1 = Modbus ASCII.
10,016 Baud Rate This is the baud rate to be used on the port. Enter
the baud rate as a value. For example, to select
19K baud, enter 19200. Valid entries are 110, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, 28800,
384 (for 38400 bps), 576 (for 57600 bps), and 115
(for 115,200 bps).
10,017 Parity This is the parity code to be used for the port.
Values are None, Odd, Even.
10,018 Data Bits This parameter sets the number of data bits for
each word used by the protocol. Valid entries for
this field are 5 through 8.
10,019 Stop Bits This parameter sets the number of stop bits for
each data value sent. Valid entries are 1 and 2.
