Technical Description

Using the UMC100 in a PROFIBUS DP Network

PROFIBUS DP is at present one of the most common fieldbus for industrial applications worldwide and
is standardised in IEC61158 together with other fieldbus protocols. The PROFIBUS DP standard has de-
fined different network topologies. The most commonly used one is the 'Party Line' topology where one
device is connected after the other.
PROFIBUS DP has evolved over time. The first services offered by PROFIBUS DP are the so-called V0
services. They define block parameterisation, configuration, cyclic data exchange and diagnosis informa-
tion exchange. DP-V0 only allows the complete parameter set to be written in one block. The bus master
sends the parameter block to the slave during powering up of the slave/device. Some control systems
also allow the sending the parameter block during normal operation.
Later the PROFIBUS DP-V1 specification introduced new acyclic read/write services within the con-
text of the PROFIBUS DP-V1 expansions. These acyclic services are inserted into special telegrams
during ongoing cyclical bus operation and thus ensure compatibility between PROFIBUS DP-V0 and
PROFIBUS DP-V1.
To integrate the UMC100-FBP into a PROFIBUS network either the PDQ22-FBP or the PDP22-FBP
FieldBusPlugs can be used. PDQ22-FBP allows to connect up to four UMC100s via one bus node.
PDP22-FBP integrates one UMC100 only (i.e. one bus address per UMC100).
The diagram below shows the sketch of a PROFIBUS bus line with UMC100s integrated via PDP22 and
PDQ22. A detailed description about the creation of PROFIBUS lines using PDP22 and PDQ22 is avail-
able in the FieldBusPlug manuals.
