Changing the Baud Rate on Modbus Communication Ports for Momentum
Components Using Modsoft
Overview Each port can be configured for a baud in the range 50...19,200. Sixteen valid bauds
are user-selectable. The factory-set default is 9600 baud.
Procedure To change the baud parameter, perform the steps in the following table.
Note: If you use a baud rate lower than 4800, you should adjust the default delay
parameter. See Changing the Delay Parameter on Modbus Communication Ports
for Momentum Components Using Modsoft, p. 201
Step Action
1 Place the cursor on the current Baud entry for the Modbus port you want to enter.
Push <Enter>.

baud values.
2 Use an arrow key to toggle the cursor onto the desired baud selection in the popup
