12. Network services

12. 3. Additional functions

Besides the services of “datasharing” the communication card provides the following functions.

b Full parameters access.

By the use of indirect access, it is possible to read or write any of the internal parameters of the VSD.

This functionality is assured by these four objects:

MBOX DATA, MBOX PARAM, MBOX READ, MBOX WRITE.

•

Reading

Write the logic address of the parameter to the present value property of the object MBOX PARAM.

Set present value property of the object MBOX READ to “read”.

The current value of the parameter can be read in the present value property of MBOX DATA.

•

Writing a parameter

Write the logic address of the parameter to the present value property of the object MBOX PARAM.

Write the new value in the present value property of the object MBOX DATA.

Set present value property of the object MBOX WRITE to “write”.

Note: MBOX READ and MBOX WRITE automatically return back to inactive once command sent. Always return 0 when read.

Important note: The modified parameters are not saved in EEPROM non-volatile memory, If you want to do this, you need to specify it by

writing the CMI bit 1 to 1. The command is only active if the drive is stopped.

b Identification.

Information relative to the VSD are stored in a unique object: ATV 61 (Device object type). The following list of properties describes the

content of this object. The type of these properties is character string.

b Factory settings.

It is also possible to restore the settings by the use of the “ReinitializeDevice” service.

This service requires one parameter.

• Reinitialization state.

The value of the Reinitialization state parameter may be WARMSTART, STARTBACKUP, ENDBACKUP, STARTRESTORE. For the VSD

the value of this parameter should be WARMSTART. The other values have no action and will be rejected.

b Freely assignable objects.

The binary value objects BV18 to BV22 correspond to bits (C311 to C315) within the ATV.

By default these bits are not used, but it is possible to assign them to an additional function. The HMI (or the commissioning software) must

be used to configure the use of these objects.

The details of the assignment possibilities of these bits are explained in the “Programming guide”.
