Value Description
Yes or No Specifies whether or not the port and commands are
active upon module boot-up.
Master, Slave, or This parameter specifies which device type the port
Slave with Pass- emulates. See Slave Mode (page 72) for more information
Through on Slave Pass-Through options.
Yes or No Use Floating point data offset.
RTU or ASCII Specifies the Modbus protocol for the port.
Multiple options Specifies the baud rate for the port.
None, Odd, Specifies the type of parity error checking. All devices on
Even this port must use the same parity setting.
7 or 8 Sets the number of data bits for each word used by the
protocol. All devices communicating through this port
must use the same number of data bits.
1 or 2 Sets the number of stop bits that signal the end of a
character in the data stream. For most applications, use
one stop bit. For slower devices that require more time to
re-synchronize, use two stop bits. All devices
communicating through this port must use the same
number of stop bits.
0 to 65535 ms Sets the number of milliseconds to delay after Ready To
Send (RTS) is asserted before data is transmitted.
0 to 65535 ms Sets the number of milliseconds to delay after the last
byte of data is sent before the RTS modem signal is set
low.
0 to 65535 ms (Slave mode) Number of milliseconds to delay before
response to a Modbus command.
Yes or No Specifies if the Clear To Send (CTS) modem control line
is to be used or not. If you set the parameter to N
CTS line is not monitored. If you set the parameter to
Y , the CTS line is monitored and must be high before
ES
the module sends data. Normally, this parameter is
required when half-duplex modems are used for
communication (2-wire). This procedure is commonly
referred to as hardware handshaking.
