Operating Behavior (PROFINET IO)
This section describes the basic behavior of the MOVI-PLC
®
advanced
DHR41B con-
troller when operated on the PROFIBUS system.
11.1 Process data exchange with MOVI-PLC
®
advanced DHR41B
MOVI-PLC
®
advanced
DHR41B is controlled via the process data channel which is up
to 2
×
32 I/O words in length. These process data words are mapped in the I/O or pe-
ripheral area of the MOVI-PLC
®
advanced
DHR41B controller, for example, when a
higher-level PLC is used as the DP master. As a result, the process data words can be
addressed in the usual manner.
Control example
for Simatic S7
Process data exchange with MOVI-PLC
®
advanced
DHR41B is controlled using
SIMATIC S7 in accordance with the selected process data configuration either directly
using load and transfer commands or by means of special system functions,
SFC 14
DPRD_DAT
and
SFC15 DPWR_DAT
.
STEP7 sample
program
In this example, the MOVI-PLC
®
advanced
DHR41B controller is configured with the
process data configuration
10 PD
on input addresses PEW512... and output addresses
PAW512....
A data block DB3 is created with about 50 data words.
