    Installation 2. INSTALLATION MODULE LAYOUT The PLX51-PBM has one RS485 PROFIBUS DP port as well as two Ethernet. The Ethernet cable must be wired according to industry standards, which can be found in the Additional Information section of this document.
  • Page 14 At the bottom of the PLX51-PBM module, there is one 3-way power connector. Figure 2.2 – PLX51-PBM Power connector The PLX51-PBM has an input voltage range of 10 to 36 VDC, applied to the module via the power connector. The power connector also provides an Earth connection for the PLX51- PBM.

    Setup 3. SETUP INSTALLING THE CONFIGURATION SOFTWARE All PLX51-PBM network setup and configuration is done in the ProSoft PLX50 Configuration Utility. This software can be downloaded from: www.prosoft-technology.com Figure 3.1. - ProSoft PLX50 Configuration Utility Environment Page 17 of 162...

  • Page 18: Network Parameters

    Setup NETWORK PARAMETERS The PLX51-PBM has DHCP (Dynamic Host Configuration Protocol) enabled as factory default. Thus, a DHCP server must be used to provide the module with the required network parameters (IP address, subnet mask, etc.). There are a number of DHCP utilities available, however it is recommended that the DHCP server in the PLX50 Configuration Utility is used.
  • Page 19 Figure 3.5. - Successful IP address assignment It is possible to force the PLX51-PBM back into DHCP mode by powering up the device with DIP switch 2 set to the On position. Page 19 of 162...
  • Page 20 Setup A new IP address can then be assigned by repeating the previous steps. NOTE: It is important to return DIP switch 2 back to Off position, to avoid the module returning to a DHCP mode after the power is cycled again. In addition to the setting the IP address, a number of other network parameters can be set during the DHCP process.

It permits sensors and actuators to be connected on one common bus line through a dedicated DP/PA gateway or link between the PROFIBUS DP and PROFIBUS PA networks, even in intrinsically-safe areas. PROFIBUS PA permits data communication and power over the bus using a 2-wire technology according to the international standard IEC 1158-2.

    PROFIBUS DP PROFIBUS MASTER CLASS 1 (DPM1) OR CLASS 2 (DPM2) PROFIBUS DP Master class 1 (DPM1) A class 1 master handles the normal communication or exchange of data with the slaves assigned to it. This is typically a PLC. It uses cyclic communication to exchange process data with its associated slaves.

    PROFIBUS DP ACYCLIC COMMUNICATION In addition to the cyclic data exchange, the PROFIBUS protocol has the option of acyclic communication. This service is not configured. There are 2 different communication channels possible between the requested master and the slave: o MS1 channel (MS1 connection): can only be established if cyclic data exchange is taking place between that master (DPM1) and the slave o MS2 channel (MS2 connection): is possible with several masters simultaneously, but the connection must be established explicitly by the master.
