Technical Description
Using the UMC100 in a PROFIBUS DP Network
PROFIBUS DP is at present one of the most common ieldbus for industrial applications worldwide and
is standardised in IEC61158 together with other ieldbus protocols. The PROFIBUS DP standard has de-
ined 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 irst services offered by PROFIBUS DP are the so-called V0
services. They deine block parameterisation, coniguration, 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 speciication 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 PDQ-FBP or the PDP-FBP
FieldBusPlugs can be used. PDQ-FBP allows to connect up to four UMC100s via one bus node.
PDP-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 PDP and
PDQ. A detailed description about the creation of PROFIBUS lines using PDP and PDQ is avail-
able in the FieldBusPlug manuals.

(CDP15) are standard extension cables to connect PDQ and UMC100.
