Starting up the inverter with INTERBUS (MCH42A)
Startup
Basic overview
The MOVIDRIVE
®
compact
MCH42A inverter offers a standardized interface for
parameterization using the "Peripherals Communication Protocol" (PCP). This
INTERBUS communication channel gives you complete access to all drive parameters
of the MOVIDRIVE
®
inverter.
The PCP channel must be configured with the corresponding ID code so you can access
parameter values in the inverter. There are one, two or four words available in the
INTERBUS protocol for the PCP channel. You can vary the speed of access to
parameter values via the PCP channel using the number of PCP words.
Additional PCP
channel for startup
and diagnostics
The PCP interface is implemented with PCP version 3. Apart from the familiar PCP
channel between the control system (PLC) and the inverter, it is now possible to
establish an additional (logical) PCP channel between the interface module and the
inverter. This additional PCP channel can be used by a supervisory computer, for
example, to access the inverter parameter values via the Ethernet / Interbus communi-
cation pathway.
Figure 158 shows an example of a system topology with Ethernet TCP/IP level and
INTERBUS level. An INTERBUS interface module with Ethernet TCP/IP interface that
functions as a gateway between the two communication levels is used for this purpose.
Apart from the "CMD Tool", the supervisory computer also runs INTERBUS
"@utomationXplorer" and "MOVITOOLS" for programming and setting the parameters
of the SEW inverter on the INTERBUS. This arrangement allows for using the existing
bus infrastructure for startup and maintenance. This facilitates startup and diagnostics
of the entire automation system because the INTERBUS cable is now not only used for
control purposes but also for startup and diagnostics of all components used on the
fieldbus.
