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.
