Port 2 Setup

File M0 Offset Register Content Description

N10:40 41 5040 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.

N10:41 42 5041 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.

N10:42 43 5042 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.

N10:43 44 5043 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.

N10:44 45 5044 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.

N10:45 46 5045 Protocol 0=RTU, 1=ASCII

N10:46 47 5046 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. Exceptions: 38400 baud, enter 384. 57600

enter 576. 115000 enter 115.

N10:47 48 5047 Parity This is the parity code to be used on the port. The

coded values are as follows:

0=None

1=Odd

2=Even

N10:48 49 5048 Data Bits This parameter sets the number of data bits for each

word used by the protocol. Enter a value in the range of

5 to 8.

N10:49 50 5049 Stop Bits This parameter sets the number of stop bits for each

data value sent. Enter a value of 1 or 2.

N10:50 51 5050 RTS On Delay This parameter sets the number of milliseconds to

delay after RTS is asserted before the data will be

transmitted. Enter a value in the range of 0 to 65535.

N10:51 52 5051 RTS Off Delay This parameter sets the number of milliseconds to

delay after the last byte of data is sent before the RTS

modem signal will be set low. Enter a value in the range

of 0 to 65535.
