Introduction
1.1 Overview
The Limitorque Master Station II is a revolutionary step forward in control technology. The device is
capable of controlling up to 250 actuators, offers full redundancy, provides easy-to-use HMI interfaces,
and allows for high-speed data-transfer via a Modbus DCS port or Modbus Ethernet port. In addition, a
built-in web server can be used for monitoring network status from any remote station using TCP/IP. Web
server operation is covered in Section 18.
1.2 User Rights Overview
The Master Station requires users to login. Three user role levels are provided: View, Control, Configure.
Each role includes the rights of the lesser roles, i.e. Control includes View’s rights, and Configure includes
Control’s rights and View’s rights.
View: the user can view the network status and the activity log. No control or configuration functionality
is available.
Control: in addition to View’s rights, the user has the ability to control MOVs.
Configure: in addition to Control’s rights, the user has the ability to configure the Master Station and
the Network.
The default passwords for each role are:

These passwords can be changed by the Configure user. Changing passwords is discussed in Section 9.
