Profibus module to BaseFcPPO3 with protocol PPO3.

 The object is created by the profibus configurator under a
 Pb_Dp_Slave object in the node hierarchy. Select BaseFcPPO3PbModule
 as Module Class in the profibus configurator.

 Connect the module object to an object of class or subclass of
 BaseFcPPO3 with the IoConnect method.

 The BaseFcPPO3 object displays the current and torque values, which
 should be configured to the process data PZD3 and PZD4 from the
 converter.

 The yellow area shows the most important channels.

 NoteThere are manufacturers with another interpretation of the PPO protocol.
 The BaseFcPPO3 object might not fully work with these converters.

Configuration

 To configure the Profibus communication, you create a slave object under the
 Profibus master object. Create an object of class Pb_DP_Slave, insert the
 gsd-file for the converter, and open the Profibus configurator from the popup
 menu for the slave object (ConfigureSlave).

 This is an example for an ABB converter.
 1. Create a slave object of class Pb_DP_Slave below the Profibus master object.
 2. Enter the gsd-file, $pwr_exe/abb_acs_pb_slave.gsd, into the GSDfile attribute.
 3. Activate 'ConfigureSlave' in the popup menu for the slave object.
    - select BaseFcPPO3PbModule in 'Module Class'.
    - set 'PrmUserData/Operation mode' to 'Vendor specific'.
    - set 'PrmUserData/Protocol' to 'PPO3'.
    - set Cut-Off time to 1. Specifies time when handling profibus errors.
 4. Connect a PlcThread object to the slave and module objects.
 5. Enter the Profibus address in the SlaveAddress attribute of the slave object.
 6. Set WdFact1 and WdFact2 in the slave object, which defines the time for the
    watchdog handling, i.e. the time before the converter is tripped when communication
    is lost (if it is configured to trip).
    The time in milliseconds is 10 * WdFact1 * WdFact2. For example if WdFact1 is 10 and
    WdFact2 is 5 the watchdog time is 0.5 s.
 7. Connect the module to the main object of type BaseFcPPO3 in the plant hierarchy with
    the IoConnect function.

 PDZ3 and PDZ4 should be configured for current and torque in the converter.

 The conversion of the converter signals to process value units is made in the
 ChanAi and ChanAo, i.e. set the range values of the channels
 -O_REF     Reference
 -I_ACT     Actual value
