4.2 Parameterisation of Modbus-TCP user
Before connecting the motor controller to the Modbus master, parameterise the controller interface,
device profile, TCP-Port and Timeout:
– with the FCT plug-in CMMO-ST
è
section 4.2.1
– with the integrated web server

Help for the FCT plug-in CMMO-ST.
2. On the application data page (Application Data), determine the control interface (Control Interface):
– “Modbus/TCP”
3. Optionally determine on the controller page (Controller):
– Enable with (Enabled by), determination of the required signals for controller enable:
– “Fieldbus” (Fieldbus) – factory setting
– “Digital input ‘Enable’ and fieldbus” (Digital Input 'Enable' and Fieldbus)
4. On the fieldbus page (Fieldbus), operation parameters tab (Operation Parameters), determine:
– Device profile (Device Profile):
– “FHPP standard”
– “FHPP st FPC”
– Optionally, change TCP-Port (factory setting TCP-Port 502)
– Optionally activate timeout (Timeout) (factory setting: 100 ms, not activated)

5. Establish an online connection.
6. Activate device control (Device Control).
7. Download and save (Store) the parameters.
8. Optionally, on the Controller page, network settings tab (Network Settings), change the network
settings (Setup network settings):
– “DHCP server active” (DHCP server active, factory setting)
– “Obtain IP address automatically” (Obtain an IP adress automatically)
– “Use the following IP address” (fixed setting IP address, subnet mask and standard gateway)
A restart is required after changing and storing the following parameters with the FCT
plug-in to make the settings active:
– control interface (Modbus, IO-Link, I-Port)
– interface parameters (device profile, TCP-Port)
– Network settings
After parameterisation and restart of the motor controller, the Modbus master can be configured
