EIP-200S Ethernet/IP Adapter
2.1 Operation
User Configured Mode
When operating in user configured mode, the EIP-200S Ethernet/IP Adapter I/O sizes, I/O
module parameterization data, and I/O configuration data is stored in nonvolatile memory
and accessed via the Slot Object. In user configured mode:
● Electronic module parameter data can be modified, 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 EIP-200S Ethernet/IP Adapter 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):
● Slot Object instance attributes can be set, providing no I/O connections are open.
● The I/O data format is defined by the user by using the combination of modules
configured.
● I/O module grouping is available but must be specified by the configuration selections.
Note
The EIP ET200 Configuration Tool is suggested for configuration of a EIP-200S
Ethernet/IP Adapter in user configured mode.
This tool is available on the Companion Disk that shipped with the product, or via
download from the Siemens Service & Support Website
(http://support.automation.siemens.com).
I/O status byte
The IO_StatusEnable attribute of the Adapter Object allows you to enable or disable the
generation of an additional I/O status byte to detect faults in the EIP-200S Ethernet/IP
Adapter. 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 flashed 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.
Configuration
Changes to user configuration data take effect immediately without resetting the device.
Changes to user configuration data are stored in nonvolatile memory and on the SD card
immediately (before the explicit message response is sent).
Module grouping
For more efficient use of address space and data transfer, the EIP-200S Ethernet/IP Adapter
supports the grouping of electronic module data. In AutoConfig mode, the electronic module
data is always grouped. See the topic entitled "Configuring the ET 200S" for details about
grouping of module data.
