Serial Communication
MOVILINK
®
protocol
The MOVILINK
®
profile enables the uniform transmission of user data between SEW in-
verters as well as via various communications interfaces to higher-level automation
equipment. Consequently, MOVILINK
®
guarantees a control and parameter setting con-
cept that can be used regardless of the fieldbus for all current bus systems, such as:
•
PROFIBUS-DP
•
INTERBUS with fiber optic cable
•
CAN
•
RS-232
•
RS-485
The MOVILINK
®
protocol for serial interfaces in the new SEW range of inverters,
MOVIDRIVE
®
and MOVIMOT
®
, enables you to set up a serial bus connection between
a higher-level master and several SEW inverters. For example, masters may take the
form of programmable logic controllers, PCs or even SEW inverters with PLC functions
(IPOS
plus®
). Generally speaking, the SEW inverters function as slaves in the bus sys-
tem.
The MOVILINK
®
protocol allows both of the following applications to be implemented:
automation tasks such as control and parameter setting of the drives by means of cycli-
cal data exchange, startup and visualization tasks.
Features
The principal features of the MOVILINK
®
protocol are:
•
Support for the master/slave structure via RS-485 with one master (single master)
and at most 31 slave stations (SEW inverters).
•
Support for point-to-point connection via RS-232.
•
User-friendly implementation of the protocol in a straightforward and reliable mes-
sage structure with fixed message lengths and a unique start identifier.
•
Data interface to the basic unit in accordance with the MOVILINK
®
profile. This
means the user data sent to the drive are transmitted to the inverter in the same way
as via the other communications interfaces (PROFIBUS, INTERBUS, CAN etc.).
•
Access to all drive parameters and functions, so they can be used for startup, ser-
vice, diagnostics, visualization and automation tasks.
•
Startup and diagnostic tools on the basis of MOVILINK
®
for PC (e.g.
MOVITOOLS/SHELL and MOVITOOLS/SCOPE).
Please refer to the 'Serial Communication and System Bus (SBus)' manual for a detailed
description of the MOVILINK
®
protocol. This manual is available from SEW-
EURODRIVE.
