9.2.3 Mounting the expansion module
If the converter is ordered with Profibus option included, the Profibus DP expansion module is
already pre-mounted inside the converter. If this option is ordered separately, the module shall
be mounted inside the converter following the instructions below.
How to get started:
• Make sure the converter to be used is switched off.
• Open the front and locate the bus module connector.
• Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module.
• Mount the module into the box, be careful to fit all 34 pins into the socket.
• Fasten the three M2.5x5 screws.
• Set the rotary switches to the desired node address, or to "0 0" if you want to configure the
address in the converter menu "Settings / Profibus".
• Set the bus termination switch in position "On" if this is the last unit on the bus, else set it to
"Off".
• Connect the Profibus network to the screw terminals according to the table below.
• Switch on the power to the converter box and check that the green led on the module starts
flashing.
• If you have not set the address switches on the module you must set the node address in the
converter menu "Settings / Profibus", exit the menu and then switch the power off at least
10 seconds before it is switched on again.
• Check in the converter menu "System / Profibus" that the module is found and initiated.
• Configure the master system (PC, PLC or DCS) to communicate with the converter at the
selected node address using the data structure described in the following chapter.
• When the communication starts working the red LEDs in the lower right corner of the module
will go dark, and the green LED will light up.
• In the converter menu "System / Profibus", "Online" will shift to "Yes". Now the Profibus
communication should be working.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
CAUTION!
Connect yourself and the converter chassis to protective ground before opening the antistatic
package of the module!
This will avoid static discharges that can damage the module or the box.
