Using the UMC100.3 in a PROFIBUS DP Network

PROFIBUS DP is at present one of the most common fieldbus for industrial applications worldwide and is standardised in
IEC 61158 together with other fieldbus protocols. The PROFIBUS DP standard has defined different network topologies.
The most commonly used one is the 'daisy chain' 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 information exchange. DP-V0 only al-
lows 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 sending the parameter block during normal operation.
Later the PROFIBUS DP-V1 specification introduced new acyclic read/write services within the context of the ROFIBUS 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. UMC100.3 is integrated in a Profibus DP network by using a
PDP32 communication interface.
The diagram below shows the sketch of a PROFIBUS bus line with UMC100.3 devices. A detailed description about the PDP32
and different possiblities to use it is available in the PDP32 manual.

PROFIBUS Line with UMC100.3 and PDP32.

Use standard PROFIBUS cable for wiring. It is also possible to mount the PDP32 remote from
the UMC. See PDP32 manual for more information. Instead of directly connecting the PROFIBUS
cable to the PDP32 X4 terminals also DSUB-9 connectors can be used and connected to X3
