It has a flexible architecture that allows the access to remote modules via different fieldbuses. The I/O modules and fieldbuses head can communicate with Altus equipment and CPUs from another manufacturers. Therefore Altus PROFIBUS DP Head PO5063 module can be connected to DeltaV/ EMERSON according following picture. The PROFIBUS DP remote maintenance is simplify by an extensive diagnostic information and hot swap capability in all I/O modules. These characteristics are included in Ponto Series modules.

Configuration 3.1 PROFIBUS DP Network Project The software Exploring DeltaV is used to create and configure the project of a distributed PROFIBUS DP remote I/O network. The DeltaV Controller will be the master of the net. It will not be described the process of DeltaV software installation and license. It is considerate that the software is installed and working properly. The Software DeltaV used for development is the V7.1. version. Altus Sistemas de Informática S.A. Página: 3
(1) Start the software DeltaV (interface Exploring DeltaV). (2) Configure the Controller : PlantWeb Systen Configuration.. CTRL-1(Master). (3) Select the module PROFIBUS DP: CTRL-1 I/O CXX ( posicion). This example will use the position (C07) for the module PROFIBUS DP. (4) Configure Port P01: C07 P01 ( right button / mouse ) Properties. (5) Enable Port P01, set the baud rate and address, which will be the Master PROFIBUS DP address.

(6) Verify if the Slave PROFIBUS DP shows in the hardware catalog (in our case the PO5063 head), otherwise it is necessary to install the GSD file following the next steps. (7) Add the equipment GSD file: Library Profibus DP Devices. (8) Use the right button on Profibus DP Devices and choose Add Device Definition to add the PROFIBUS DP Head PO5063 as Slave PROFIBUS DP module. Altus Sistemas de Informática S.A. Página: 5
(9) In the previously window select the GSD file (from PO5063 module). Each kind of equipment has his own configuration parameter that is define by the manufacturer. The parameters are listed in the GSD file. (10) Now the PO5063 can be added as slave Profibus Device: I/O P01 New Profibus Device. (11) Select PO5063 using the DeltaV Browser. Altus Sistemas de Informática S.A. Página: 6
(12) The PO5063 will appear in the list of Port P01 Devices PROFIBUS DP and can be enable and configured by the window PO5063 Properties. (13) The PO5063 is enable in this window and can be added a description. The address is set according the physical address of the PROFIBUS DP Head (PO5063). (14) With the head already set and addressed it is necessary to add Slots (I/O modules) according the configuration: PO5063 Right button / mouse New Profibus Slot. (15) Once the Slots are inserted (according the I/O modules) it is time to configure and set each Slot. The option Properties of each Signal will set and configure the Slot, according the following picture: Altus Sistemas de Informática S.A. Página: 7
(16) After Exploring DeltaV configuration it is necessary the transference of information to memory. We can check the diagnostic of the PROFIBUS DP Slave according the following picture (DeltaV Controller must be in operation mode and physical connections done): The parameter Diagnostic Messages must be set or reset to avoid the operation mode information as diagnostic message in the PO5063 module.

3.2 PROFIBUS DP Setting The Ponto Series modules need a parameterization to define operation modes. It exist common parameters and specific parameters for each module. The parameters are specified by the GSD file. The PO5063 head has the following common parameters. Parameter Option Description Hot swap disable When the system is turned on all the modules must be connected in the bus. They can t be removed during on line mode operation. Hot swap enable with no start The missing of declared modules on the bus or the remove of the modules during on line Power up system up consistency operation will not affected the power on and head on line mode operation. Operand forcing Disable Output Diagnostic Messages Delay time to module activation Hot swap enable with start up consistency (default) It does not allow operand forcing (default) It allows operand forcing It does not allow output disabling It allows output disabling Status and diagnostic errors (default) Only diagnostic errors No delay time 1 second delay 2 seconds delay (default) 3 seconds delay 5 seconds delay 10 seconds delay All the declared modules must be placed on the bus during the power on of the system. After power on the modules can be replaced for maintenance keeping the head on line operation. The operand forcing by software is not allowed (invalid code). The operand forcing is allowed. The output disabling is not allowed by programming software (invalid code). The output disabling is allowed by. The extended diagnostic messages report the status operation of the head and modules, also indicates errors. The diagnostic messages only report errors. The scan time of the module will be active immediately after physical detection. The scan time of the module will be active 1 second after physical detection. The scan time of the module will be active 2 second after physical detection. The scan time of the module will be active 3 second after physical detection. The scan time of the module will be active 5 second after physical detection. The scan time of the module will be active 10 second after physical detection.

Maintenance The base design, hot swap characteristics and fully diagnostic information are characteristics from Ponto Series that facilitate the maintenance of the system. The report of failures, diagnostics and operation modes give to the operator fully control to identify and solve any problem. 4.1 Diagnostic LEDs All the Ponto Series modules have diagnostic LEDs to inform status and operation mode by easy and quickly way. The LED DG is a common sign used in all Ponto Series modules. It indicates any abnormality in the operation mode according blinking codes. The LED DG can blink up to 5 times, indicating the status according the following table. LED DG Status Always On Blinks 1x Blinks 2x Blinks 3x Blinks 4x Blinks 5x Always Off Mode Description Module is configured and accessed by the master. Properly operation. The module is not access by the master. This situation automatically disable the outputs. Fuse damage. External power supply (24V) failure. The module has diagnostic (channels). Not used. It will occur only in case of hardware damage in the module, not working LED or the module is not connected in the bus. The PO5063 Utilization Manual must be consulted for complete description of the diagnostic LEDs, possible causes and solution procedures. Altus Sistemas de Informática S.A. Página: 10
4.2 Diagnostic Messages The diagnostic messages can be displayed on HMI or programming software that are connected to the RS232 port of the PROFIBUS DP head. The information will be placed in the memory of the PO5063 head, operand M512 to M641. Total of 210 Operands M or 420 bytes: the first 20 bytes are used with diagnostic system, followed by 400 bytes with modules diagnostic information (40 segments, 1 segment for each module connected on the GBL bus). The PO5063 Utilization Manual must be consulted for a complete description of diagnostic information through RS232 port. The diagnostic messages are transferred to the master via PROFIBUS DP network and they are available for the application or to be monitored through network configuring software. The diagnostic messages can be displayed in the Exploring DeltaV during online mode. The slave PROFIBUS DP must be select to see the information.
