2 YSPI4-232/485
Introduction
This user manual supports you in the planning, connecting,
configuring and parameterization of the YSPI4. It is geared towards
persons who can program PLC systems (SIMATIC). SIMATIC is a
registered trademark of Siemens AG. Version 1.2, as of: March 1998
The YSPI4 (serial PROFIBUS gateway) enables a PROFIBUS DP
master to communicate with a field device with a serial interface.
The YSPI4 is used to turn the field device with a serial interface into
a real PROFIBUS subscriber. The YSPI4 does this by converting the
data exchanged between the PROFIBUS DP master and the field
device into a form that can be read by each of the devices. The data
are exchanged between the DP master and YSP14 in the form of
telegrams and/or telegram fragments via a data channel whose size
can be changed in the configuration and adjusted to the telegram
length and available PLC E/A range. The data channel consists of a
transmitting and receiving channel. When planning the YSPI4, please
take note of the general rules for planning PROFIBUS components so
that the YSPI4 can operate disruption-free.
Safety
To prevent personal injuries and material damage follow:
– Provisions for handling electrical components as per VDE 0100
– Valid safety and accident prevention regulations (UVV)
– Safety instructions
– PROFIBUS standard EN 50170
Installation
The YSPI4 may only be installed and/or removed by qualified
personnel with electrical training.
Bus cable
Only use a special, two-core, twisted and shielded PROFIBUS cable
as a bus cable. This is the only way to ensure the high transmission
rates.
