#This is an example of a Master port using Modbus RTU protocol
[Modbus Port 0]
# Settings required by both Master and Slave
Enabled : Yes #Port enable flag Y=Yes, N=No
RS Interface : 0 #0=RS-232, 1=RS-485, 2=RS-422
Type : Master #Port type M=Master, S=Slave
Float Flag : No #Use floating data type Y=Yes, N=No
Float Start : 7000 #Register offset in message for floats
Float Offset : 2000 #Internal Address for floats
Protocol : RTU #Modbus Protocol R=RTU, A=ASCII
Baud Rate : 384 #Baud rate for port
Parity : None #N=None, O=Odd, E=Even
Data Bits : 8 #5 to 8 data bits for messages
Stop Bits : 1 #1 or 2 stop bits for messages
RTS On : 0 #Delay after RTS set before msg sent (mSec)
RTS Off : 1 #Delay after message before RTS dropped(mSec)
Minimum Response Delay : 2 #Number of mSec to delay before respose
Use CTS Line : No #Monitor CTS modem line (Y/N)
Response Timeout : 1000 #mSec for response timeout of command
Retry Count : 2 #retry count for failed requests
