How to Access FC 300 Parameters

PCV Parameter Access

Parameter access via the PCV channel is performed by the PROFIBUS DP V0 cyclical data exchange, where

the PCV channel is part of the PPOs described in the chapter How to Control the FC 300.

PCV

PCA

IND

PVA

CTW

MRV

MAV

Byte

no.

Type

PCV:

Parameter Characteristics Value

PCD:

Process Data

PCA:

Parameter Characteristics (Bytes 1, 2)

IND:

Sub index (Byte 3. Byte 4 is not used)

PVA:

Parameter value (Bytes 5 to 8)

CTW:

Control word

STW:

Status word

MRV:

Main reference value

MAV:

Main actual value (Actual output frequency)

Using the PCV channel it is possible to read and write parameter values, as well as readout of a number of

describing attributes of each parameter.

PCA Handling

The PCA part of PPO types 1, 2 and 5 can handle several tasks. The master can control and supervise

parameters and request a response from the slave, whereas the slave can respond to a request from

the master.

Requests and responses

is a handshake procedure and cannot be batched, meaning that if the master sends

out a read/write request, it has to wait for the response, before it sends a new request. The request or

response data value will be limited to maximum 4 bytes, which implies that text strings are not transferable.

For further information, please see the

Application Examples chapter

PCA - Parameter Characteristics

SMP

PNU

RC: Request/response characteristics (Range 0..15)

SMP: Spontaneous Messag (Not supported)

PNU : Parameter no. (Range 1..1999)
