Establishing The Connection; Configuration And Parameter Setting Of I/O Modules - WAGO -I/O-SYSTEM 750 Technical Description, Installation And Configuration

3.1.5.4

Establishing the Connection

Before starting the productive data exchange between the I/O controller and
the I/O device, individual communication instances are created within the
PROFINET IO context management and the I/O configuration (target
configuration) of the modules is notified. After the connection structure has
been checked and once the actual configuration has been adjusted (optional),
the I/O device receives all necessary operating settings (parameters) so that
the cyclic data exchange via "record data" sets can be established. Both the
buscoupler and the connected I/O modules are supplied with parameters. Once
all settings have been made, the I/O device signals that it is ready to send and
receive cyclic productive data.

3.1.6 Configuration and Parameter Setting of I/O Modules

Setting the parameters of I/O modules is performed via "record data" sets.
Modules with diagnostics capability allow the diagnostics message to be
locked or released for each channel. Digital outputs provide the possibility of
switching a configurable substitute value for each channel in the case of
invalid output information.
Possible configuration and parameter values can be found in chapter 5.3,
"Configuration and Parameter Setting of the Modules".
Note
For simplification, only the item numbers are shown as module designation in
the table. Therefore, the module "75x-400" corresponds to module "750-400
2 DI/24 V DC/3.0 ms" or
"753-400 2 DI/24 V DC/3.0ms"
