Connectable devices
The following Schneider Electric devices can be connected to this bus:
b
TeSys U and TeSys T starter-controllers
b
Momentum and Modicon STB distributed I/O
b
Altivar 312/61/71 variable speed drives for asynchronous motors
b
Lexium 05/15 servo drives for brushless motors
b
Altistart ATS 48 soft start-soft stop units
b
Any third-party device compatible with Profibus DP and PA standard profiles
Limitations
Once saved, the Unity project incorporates all the Profibus parameters as well as
those of the slaves connected to the bus. Modicon Quantum, Modicon Premium and
Modicon M340 PLCs are capable of embedding all this data so that an empty Unity
terminal without any applications is able, after a simple transfer from the PLC, to
locate the whole application, including the slave parameters. This function is called
ETS
(
Empty Terminal Service)
.
In certain cases, it may be that the memory size required to save the device parameters
exceeds the PLC memory capacity (signalled by a “memory full” message during the
build). This is particularly likely on devices which have DTM (the most common
instrumentation on PA). Typically, each device of this type takes up around 20 KB of
the PLC memory.
It is therefore essential to create a memory map according to the type of configuration
used and possibly adapt it accordingly, either by increasing the amount of memory
dedicated to the application (by reducing the zone allocated to data), or by increasing
the overall memory via cartridges available in the catalogue.
If the ETS function is not required, Unity Pro can also be configured in such a way as
to reduce the size of the embedded data by disabling comments and animation
tables, or by disabling the upload function so that the application does not include
data relating to DTMs. In this case, the upload from an empty terminal function is no
longer available.
