The ET 200pro EtherNet/IP module
3.2 Operation
User-configured mode
When operating in User-configured mode, the ET 200pro EtherNet/IP module I/O sizes, I/O
module parameterization data, and I/O configuration data are stored in nonvolatile memory
and accessed via the Slot Object. In User-configured mode:
● You can modify electronic module parameter data, allowing access to more advanced
configuration options and diagnostics.
● I/O configuration is verified. Mismatching I/O configurations result in an error.
Note that the ET 200pro EtherNet/IP module is unable to differentiate modules of similar
configuration types (for example, a 2 A discrete output module as compared to a 0.5 A
discrete output module).
● You can set Slot Object instance attributes (as long as there are no open I/O
connections).
● You define the I/O data format by the combination of modules you configure.
● I/O module grouping is available, but you must define it by your configuration selections.
Changes to configuration data
Changes to user configuration data take effect immediately after download without resetting
the device.
Changes to user configuration data are stored in nonvolatile memory immediately (before the
explicit message response is sent).
Setting the IP address
DHCP is the factory default. When the ET 200pro EtherNet/IP module is using DHCP, you
can set IP addresses by using Microsoft Windows and Linux DHCP/BOOTP servers. There
are several free servers for Microsoft Windows available for download from the Internet. Use
discretion when downloading software from the Internet.
After you set the IP address with DHCP, you can use the EIP ET200 Configuration Tool to
set a permanent IP address and turn off DHCP. See the "EIP ET200 Configuration Tool User
Reference Guide" for detailed instructions.
I/O status byte
The Adapter Object IO_StatusEnable attribute allows you to enable or disable the generation
of an additional I/O status byte to detect faults in the ET 200pro EtherNet/IP. If the
IO_StatusEnable attribute is TRUE (1), an additional status byte is placed at the beginning of
the input data packet, prior to any electronic module data. In the event of a fault, the status
byte is set to 1, and the I/O status LED flashes red while I/O is active.
If the IO_StatusEnable attribute is FALSE (0), the input data packet contains only electronic
module data as configured.
