    PIO P O-System arker I/O-SYSTEM 2.6.4 Power Supply Unit The I/O-SYSTEM requires a 24 V direct current system supply with a maximum deviation of -15% or +20 %. Recommendation A stable network supply cannot be taken for granted always and everywhere. Therefore, regulated power supply units should be used in order to guarantee the quality of the supply voltage.
  • Page 25 I/O-SYSTEM 2.7.2 Grounding Function The grounding function increases the resistance against disturbances from electro- magnetic interferences. Some components in the I/O system have a carrier rail contact that dissipates electro-magnetic disturbances to the carrier rail. Fig. 2-13: Carrier rail contact Attention Care must be taken to ensure the direct electrical connection between the carrier rail contact and the carrier rail.
  • Page 26 PIO P O-System arker I/O-SYSTEM 2.7.3 Grounding Protection For the field side, the ground wire is connected to the lowest connection terminals of the power supply module. The ground connection is then connected to the next module via the Power Jumper Contact (PJC). If the bus module has the lower power jumper contact, then the ground wire connection of the field devices can be directly connected to the lower connection terminals of the bus module.

    PROFIBUS 5 PROFIBUS 5.1 Description PROFIBUS is an open fieldbus standard, laid down in the European Standard EN 50170, Vol. 2 (also IEC). PROFIBUS DP has been designed for a fast and efficient data exchange between a control (PLC / PC) and decentralized peripheral equipment, for example sensors and actuators, digital or analog input and output modules.

    PIO P O-System arker PROFIBUS 5.2 Wiring On the PROFIBUS with RS 485 transmission technology all devices are connected in a line structure. The bus line comprises of a twisted and screened pair of wires. The fieldbus line is specified in EN 50170 as a line type A and must provide certain line parameters.
  • Page 111 PROFIBUS Note When connecting the subscriber ensure that the data lines are not mixed up. The bus termination at the start and end of the bus line must be installed. The bus connection requires the supply voltage VP from the device. For this reason ensure that the slave unit installed on the bus termination, is always supplied with voltage.
