2.1 PZD Process Data Process data interconnection involves the linking up of setpoints and control bits to the RAM interface of the drive. The transferred process data only becomes effective when the used bits of the control words as well as the setpoints, status words and actual values are connected to the dual-port RAM interface. The CBP stores the received process data at fixed pre-determined addresses in the dual-port RAM. Each item of process data is assigned a connector. The connector is also used to determine whether the PZD is a 16-bit value or a 32-bit value. With the help of selector switches, the setpoints or the individual bits of the control words can be assigned to a particular PZD in the dual port RAM. In order to do this the connector belonging to the required PZD is assigned to the selector switch. YOU MUST ASSIGN BICO BINNECTORS AND CONNECTORS IN THE DRIVE PARAMETERS. See MASTERDRIVE Compendium function diagrams [120] (Receive) and [125] (Send) for Binnectors and Connectors in the Drive. If the first Word of data transmitted to the drive is to be used as a Control Word, BICO programming must occur in Control Word 1 of the MasterDrive [180]. Please note that BIT 10 must be asserted. BIT 10 is the LIFE BIT and must be asserted for the Drive to receive control from Profibus. Note that to turn the dri ve on P554 must be explicitly programmed. (e.g. P554 = B3100).
Process Data Transfer must be programmed in PLC program. The rules of consistent data apply to transferring PZD data. Consistent data must be sent together. SFC14 and SFC15 are used to send and receive the data in the PLC program. The PZD data is sent to the Peripheral Output addresses that were assigned during hardware configuration. This will be shown in the following section’s examples.

2.2 PKW Parameter Data PKW Parameter Data is used to monitor parameter values, as well as to transfer and acknowledge parameter changes. The parameter area always contains at least four words. The first word of the PKW Data is used to request a task and identify the parameter number. The second word indicates the parameter index. The third and fourth words are used to pass parameter values. The following Tasks are possible with PKW Parameter Data.
Task ID Significance (Decimal ID #) 0 No task 1 Request parameter value 2 Change parameter value (word) 3 Change parameter value (double word) 4 Request description element 5 Change description element (not with CBP) 6 Request parameter value (array) 7 Change parameter value (array, word) 8 Change parameter value (array, double word) 9 Request the number of array elements 10 Reserved 11 Change parameter value (array, double word) and store in the EEPROM 12 Change parameter value (array, word) and store in the EEPROM 13 Change parameter value (double word) and store in the EEPROM 14 Change parameter value (word) and store in the EEPROM 15 Read or change text (not with CBP)

The 3 and 4 words that are transmitted are used as the speed reference. The 3 word is the high word and the 4th word is the low word. Note that 4000 Hex rd represents 100% speed and 1000 Hex represents 25% speed in the 3 word. The fourth word is of lower significance, however it can be used to set very slow speeds.

Assert the Modified Values by clicking the “Modify” Hot Button. This looks like a lighting bolt. CAUTION: THE DRIVE WILL TURN ON AND THE MOTOR WILL TURN AT THE SETPOINT SPEED.
PZD Data Modification is now complete. This demonstration outlines how to configure the drive, soft-wire binectors and connectors, create a VAT table, and modify values.

Table Task IDs (master -> converter)
Word 1 Consists of the Task ID and the Parameter Number.
For this example we choose Task 12 (Decimal). This will change a single word parameter and store the results in the MASTERDRIVE EEPROM. Note that if the EEPROM Task is not selected the changes will only occur in RAM and this state will not exist after a power cycle. If a parameter is going to be continuously changed by the program the parameter should be stored in the drive’s RAM because the EEPROM can only be written to a limited amount of times. The Task and Parameter Number will be passed over via a VAT Table. We will need to convert this into Hexadecimal format. Word 1 Format: Bits 0 to 10 represent the Parameter Number. Bit 11 is the toggle bit for parameter change reports. Bits 12 to 15 contain the task ID and reply ID Bits 15 14 13 12 ~ 11 10 9 8 ~ 7 6 5 4 ~ 3 2 1 0 Decimal ---- 12 ----- ------------- P554 -----------Binary 1 1 0 0 ~ 0 0 1 0 ~ 0 0 1 0 ~ 1 0 1 0 HEX ---- C ------ ---- 2 ---- ~ --- 2 --- ~ --- A--Therefore for PKW Word 1 will transmit C22A Hex to change P554 in the drive’s EEPROM.

Word 2 Consists of the Array Sub-Index and the MASTERDRIVE specific Page Select.
For cyclical communication by means of PPOs the following word arrangement is used. Bits 0 to 7 are used for Page Selection Bits 8 to 15 are used for the Parameter Index. Page Selection: Parameter designation (acc. to parameter list)
Serial parameter number
P000 - P999 (r000 - r999) H000 - H999 (d000 - d999) U000 - U999 (n000 - n999) L000 - L999 (c000 - c999)

Required addressing of the parameter via PROFIBUS PNU PNU [decimal] [hex.] 0 - 999 0 - 3E7 1000 -1999 3E8 - 7CF 0 - 999 0 - 3E7 1000 - 1999 3E8 - 7CF
Bit #0 =0 =0 =1 =1
For our example we are changing P554, therefore the Page Selection Bit #0 = 0 and Bits 0 to 7 = 0. Parameter Index:
P554 is an indexed parameter. The MASTERDRIVE has BICO Data Sets to change it’s configuration without reprogramming. This utilizes index parameters. By default the first index is the active Data Set, therefore we must select index one of P554. Indexed parameters may range from 0 to 255 Decimal, 0 to FF Hex. To indicate the Index = 1, the th th th 8 bit =1. (Example: If the Index = 2, then 9 bit = 1 and 8 bit = 0) Word 2 Bits 15 14 13 12 ~ 11 10 9 8 ~ 7 6 5 4 ~ 3 2 1 0 Binary 0 0 0 0 ~ 0 0 0 1 ~ 0 0 0 0 ~ 0 0 0 0 HEX ---- 0 ------ ---- 1 ---- ~ --- 0 --- ~ --- 0--PKW Word 2 is 0100 Hex. This represents the first index of a Parameter in the range of 0 – 1999.
Word 3 & Word 4 Consists of the data to be transferred.
The parameter value (PWE) is always transferred as a double word (32 bit). PWE is split into PWE1 and PWE2 (16 bit). rd
PWE1 (Most Significant Word, 3 Word) PWE2 (Least Significant word, 4th Word). A 32-bit parameter value is composed of PWE1 and PWE2. A 16 bit parameter value is transferred in PWE2, in the case that you have set PWE1 to 0. Hex values are used to set the parameter value. This Example passes two different 16 bit parameter. PWE1 (3rd Word) = HEX ---- 0 ------ ---- 0 ---- ~ --- 0 --- ~ --- 0---- 0 ---- ---- 0 --- ~ --- 0 --- ~ --- 0--OR PWE2 (4th Word) = HEX ---- 3 ------ ---- 1 ---- ~ --- 0 --- ~ --- 0---- 0 ---- ---- 0 --- ~ --- 2 --- ~ --- 0--Therefore PKW Words 3 & 4 will transmit either 3100 Hex or 0020 Hex to change P554 On/Off command from the Profibus Receive OR Digital Input 6.
