File M0 Offset Register Content Description

N10:16 17 5016 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.

N10:17 18 5017 Parity This is the parity code to be used on the port. The

coded values are as follows:

0=None

1=Odd

2=Even

N10:18 19 5018 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.

N10:19 20 5019 Stop Bits This parameter sets the number of stop bits for

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

N10:20 21 5020 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.

N10:21 22 5021 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.

N10:22 23 5022 Minimum Response

Delay

This parameter sets the number of milliseconds to

wait before a response message is sent out of the

port. This parameter is required when interfacing to

a slow responding device. Enter a value in the

range of 0 to 65535.

N10:23 24 5023 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. Normally,

this parameter is required when half-duplex

modems are used for communication (2-wire).

N10:24 25 5024 Slave ID This parameter defines the virtual Modbus slave

address for the internal database. Any requests

received by the port with this address will be

processed by the module. Verify that each device

has a unique address on the network.

N10:25 26 5025 Bit Input 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.

N10:26 27 5026 Word Input Offset This parameter specifies the offset address in the

internal Modbus database for network requests 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.
