6 Operation
6.1 Requirements for Successful Operation
The device has been designed for use in a system complying with the PROFINET standard. For successful operation, the controller
must also support all functions and interfaces described in this manual.
6.2 Device Classification
The PROFINET Module is a PROFINET I/O-device and must be managed by an I/O-controller over Ethernet.
6.3 Master Configuration
Import the latest GDSML file into the Master configuration tool. This file is available from the website. SSPM_N.bmp indicates nor-
mal mode. SSPM_D.bnp indicates diagnostic mode.
6.4 Enabling Network Control
MCD 200
For the soft starter to accept the fieldbus commands, a link must be fitted across terminals A1–N2 on the soft starter.
MCD 500
Input links are required across terminals 17 and 25–18 if the soft starter is being operated in auto-on mode. In hand-on mode, links
are not required.
Control via the fieldbus communication network is always enabled in local control mode and can be enabled or disabled in remote
control mode (
parameter 3-2 Comms in Remote
). See the VLT® Soft Starter MCD 500 Operating Guide for parameter details.
6.5 Ensuring Safe and Successful Control
Data written to the device remains in its registers until the data is overwritten or the device is reinitialized. The PROFINET Module
will not transfer successive duplicate commands to the soft starter.
If the soft starter is started via fieldbus communications but stopped via the LCP or a remote input, an identical start command
cannot be used to restart the soft starter.
If the soft starter may also be controlled via the LCP or the remote inputs (as well as via fieldbus communications), a control
command should be immediately followed by a status query to confirm that the command has been actioned.
