6.3 Configuring Modbus TCP via interface X1400

6.3 Configuring Modbus TCP via interface X1400
Activating Modbus TCP via X1400 (CBE20)
1. For drive object DO1, set p8835 = 5 (Modbus TCP).
2. Set the IP address for the CBE20 using p8941.
3. Set the standard gateway for the CBE20 using p8942.
4. Set the subnet mask for the CBE20 using p8943.
5. Set the DHCP mode for the CBE20 using p8944.
6. Select the setting "Activate and save configuration" as interface configuration using
p8945 = 2.
7. In the Startdrive commissioning tool, check the list of drive objects p0978.
When required, change the sequence of the drive objects using the telegram
configuration ("Drive device" > "Communication" > "Telegram configuration").
8. Save the settings in the Startdrive commissioning tool and carry out a POWER ON.

Explanation
Connector output to interconnect the PZD received from the fieldbus controller via
IF1.
Selects the PZD (actual values) to be sent to the fieldbus controller in the word
format via IF1.
Displays the PZD (actual values) sent to the fieldbus controller in the word format
via IF1.
Status display for the internal communication interface.
Setting the monitoring time to monitor the received process data via the COMM
BOARD.
If, within this time, the Control Unit does not receive any process data from the
COMM BOARD, then the drive shuts down with fault F08501.
Assigning the CBE20 interface (x1400) for cyclic communication via PZD interface
1 (IF1) and interface 2 (IF2).
Connector output to interconnect the PZD (setpoints) received in the word format
via IF2.
Selects the PZD (actual values) to be sent in the word format via IF2.
Displays the PZD (actual values) sent in the word format via IF2.
Status display for COMM BOARD.
