The following parameters are displayed when the Type parameter is set to
MASTER.
The following table describes the parameters in the EDIT – MODBUS PORT 1
dialog box when the Type parameter is set to MASTER.
Parameter
Description
Enabled
1 = ENABLE PORT, 0 = disable port
Type
0 = MASTER, 1 = Slave
Protocol
0 = MODBUS RTU MODE, 1 = Modbus ASCII mode
Baud Rate
Sets the baud rate for the port. Valid values for this field are 110, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, 384 or 3840 (for 38,400
baud), 576 or 5760 (for 57,600 baud) and 115,1152, or 11520 (for
115,200 baud)
Parity
0 = None, 1 = Odd, 2 = Even
Data Bits
Modbus RTU mode = 8 Modbus ASCII mode = 8 or 7
Stop Bits
Valid values are 1 or 2.
RTS On
0 to 65535 milliseconds to delay after RTS line is asserted on the port
before data message transmission begins. This delay can be used to
allow for radio keying or modem dialing before data transmission
begins.
RTS Off
0 to 65535 milliseconds to delay after data message is complete
before RTS line is dropped on the port.
Use CTS Line
NO or YES
This parameter is used to enable or disable hardware handshaking.
The default setting is NO hardware handshaking, CTS Line not used.
Set to NO if the connected devices do not need hardware
handshaking. Set to YES if the device(s) connected to the port require
hardware handshaking (most modern devices do not). If you set this
parameter to YES, be sure to pay attention to the pinout and wiring
requirements to ensure that the hardware handshaking signal lines are
properly connected; otherwise communication will fail.
