ABB Frequency converter ACS880.

 This object handles communication with an ABB ACS880 frequency converter over
 Profibus DP, protocol PPO7. The object graph and more graph below displays the
 most vital IO signals.

 In addition to the signals used by the ACS880_1, signals that can be user defined
 are present in the Profibus message. For example digital inputs Di1 to Di6 are
 normally not used by the converter, and might be used for a local start/stop unit.
 Via user status word 1 you could also get free programmable signals named
 "User 1" to "User 5". See also converter parameter group 6.71 to 6.75.
 See the Profibus module object ABB_ACS800_PPO5 for more information.

 The full value of this object will be achieved if you use object ACS880MotorAggr
 (motor, pump or fan), see class ABB_ACS880MotorAggr.

 Simple writing/reading of parameters. Press the "More.." button in the object
 graph to open the graph. The status of the two most important words are found
 here, the control word CW (write) and the status word SW1.

 For plc coding the function object ABB_ACS880_1Fo is used.
 Create a function object in the plc editor and connect it to the current
 object with the connect function.

 The function object basic task is to read and write to the converter
 statusword SW, control word CW, reference REF and actualvalue ACT.

 For simulation of ACS880_1, use the plc function object ABB_ACS880_1sim.

 There is a specific Profibus slave and module object available that can be used to
 configure the Profibus PPO5 connection, ABB_ACS880_Pb_Slave and ABB_ACS880_PPO7.
 The module object contains an ABB_ACS880_PPO7_IoModule object that contains all
 the channel objects for the communication.

 Create a slave object under the profibus master, and open the profibus configurator.
 Select the PPO7 type and the ABB_ACS880_PPO7 class.
 Then connect the IoModule object to the ABB_ACS880_1 object with the IoConnect function.
 See also ABB_ACS880_Pb_Slave for more information.

 A lot of settings are needed in the converter to match the PlcPgm code and
 the object graph, see class ABB_ACS880_PPO7 for more information.

 Consider the scale settings in the analog channel object of the
 ABB_ACS880_PPO7_IoModule object.

 -Signal ActSpeed   channel I_ACT
 -Signal ActCurrent channel I_PZD3_PZD4  (32bit)
 -Signal ActTorque channel I_PZD5

 All the signals between the converter and PLC are displayed in the figure below.

 The ACS880_1 signal interface to converter has two important words named
 controlword CW and statusword SW. The CW word are not easy to understand.
 For detailed information see ABB manuals.

 The Control word is the principal means for controlling the converter
 from a fieldbus system. The fieldbus master station sends the
 Control word to the converter through the adapter module. The converter
 switches between its states according to the bit-coded instructions
 in the Control word and returns status information to the master in
 the Status word. A detailed description of the Control word and the
 Status word is displayed in the figure below.

 Description from ABB manual.

 Descripton from ABB manual.

 ABB_ACS880_1 is derived from ABB_ACS800_1 with the following improvements

  -Safe torque off input in the converter i.e. new output [sto] in function object and new signal.
  -All fault and warning messages in text form in object graph.
  -Alarm message converter fault (inhibit) removed.
  -After a stop command it is now possible to start directly without waiting for stop to complete.
  -Graphical interface with more status and a new user status word.
  -Predefined input named "User 1" to "User 5" displayed in the object graph.
  -ConvertReady signal added that pays attention to the new STO input (safe torque off)
  -New signal "zero speed" and "magnetized" (good to have in synchronous start etc.)
