N10:5 6 5005 Error Status Pointer This parameter specifies the register location in the
module's database where module status data is
stored. If a value less than 0 is entered, the data will
not be stored in the database. If the value specified
is in the range of 0 to 4940, the data is placed in the
user data area.

Port 1 Setup
File M0 Offset Register Content Description
N10:10 11 5010 Enable This parameter defines if this port will be used. If
the parameter is set to 0, the port is disabled. A
value of 1 enables the port.
N10:11 12 5011 Type This parameter defines if the port emulates a
master or slave device. Enter 0 to emulate a master
device and 1 to emulate a slave device.
N10:12 13 5012 Float Flag This flag specifies if the floating-point data access
functionality is to be used. If the float flag is set to
Y, Modbus functions 3,6, and 16 will interpret
floating point values for registers as specified by
the two following parameters.
N10:13 14 5013 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. For example, if a
value of 7000 is entered, all requests for registers
7000 and above will be considered floating-point
data.
N10:14 15 5014 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.
For example, if the Float Offset value is set to 3000
and the float start parameter is set to 7000, data
requests for register 7000 will use the internal
Modbus register 3000.
