Module grouping
The ET 200pro EtherNet/IP module supports grouping electronic module data to enable
more efficient data transfer and use of address space. Electronic module data is always
grouped in Automatic Configuration mode. See the topic "Configuring the ET 200pro
EtherNet/IP module" for details about grouping module data.
Reset behavior
When the ET 200pro EtherNet/IP module is reset, the outputs are deactivated during the
short period that the reset is in progress. The unit can be reset in the following ways:
● by cycling of primary device 24 VDC power of the primary device
● by using the reset function in the EIP ET200 Configuration Tool.
● by sending an explicit EtherNet/IP Reset service message to instance 1 of the Identity
Object with service data of 0, 1, or 2. If service data 1 is sent, on reset the module returns
to factory default state and any user configuration is lost. If service data 2 is sent, the
module returns to the factory default state, but the IP address is maintained.
Note
When network power is removed (or if an I/O connection times out or is lost), outputs go to
their configured "substitute" value according to how the parameter is set for each I/O
module. The "default" substitute value, which is in effect in Automatic Configuration mode, is
to turn off or to zero outputs. Consult the documentation for your specific I/O module for
details. To set a non-default substitute value, you must use User-configured mode.
