8 Configuration

Module Configuration Sent with the Connection Request

Individual module configuration must be manually constructed and appended

to the minimal configuration assembly specified in the table Minimal Adapter

Configuration Assembly on page 5. For each module that needs to be

configured, the following information must be provided:

This structure may be repeated for as many modules as necessary until the

whole assembly exceeds 509 bytes. The module order is not important as long

as all module configuration follows the minimal header information from the

table Minimal Adapter Configuration Assembly on page 5.

If any part of the configuration assembly is wrong (either the minimal

assembly or a portion directed to an I/O module), the connection request will

be rejected with the General Return Code indicating an Error in the Data

Segment (0x09). The Extended Error code will indicate the byte offset into the

configuration data segment where the error was detected. The Configuration

assembly details for all of the 1734 and 1738 I/O modules are presented in

Module Assembly Information on page 31.

Module Configuration with RSNetWorx for DeviceNet

RSNetWorx for DeviceNet provides a rich parameter-based configuration user

interface. The POINT I/O and ArmorPOINT I/O adapters have the

capability to present their backplane as a DeviceNet subnet to RSLinx. The

subnet can be used to bridge configuration data from RSNetWorx for

DeviceNet to backplane devices. With this method, all configuration for a

POINT I/O backplane can be stored to the DeviceNet network file (.DNT)

and restored via this file if necessary.

Module Configuration Information

Field Data Type Description

Slot number USINT The slot number to identify modules that require

configuration data.

Configuration size USINT The size, in bytes, of the Configuration Data for the

given module. It does not include the size of the first

three fields shown here.

Configuration

assembly instance

UINT The adapter reads this field to access the module

configuration assembly’s instance number.

Configuration data Array of

BYTE

The configuration assembly data as defined by the

module's EDS file.
