Parameterization via OUT process data

Reparameterization can be carried out via the output pro-

cess data, however this is not saved permanently on the de-

vice.

The following sequence applies regardless of the format

(IB IL or S7-compatible):

–

The master interrupts the transmission of current pro-

cess data and sends parameter data (OutputProcess-

Data with bit 15 = 1)

–

The device interrupts the transmission of current pro-

cess data and responds with the following diagnostic

code in the process data:

–

If the diagnostic code is OK, the parameter data is ac-

cepted immediately. The master can end parameteriza-

tion (OutputProcessData with bit 15 = 0). The device

returns to normal operation with cyclic process data

transmission.

–

In the event of the ERROR diagnostic code, the master

can abort parameterization without modified parameter

data (OutputProcessData with bit 15 = 0) or transmit the

modified parameterization (return to step 1).

Example

The example applies to the following changes:

–

Selection of format S7-compatible (Default) to IB IL

–

For "hold last value"

Please operate the reparameterization only

by the startup of the device!

In order to start configuration, bit 15 of the out-

put word must be set to 1. If bit 15 = 0, the de-

fault configuration is active.
