Object Description
This object implements Modbus related settings in the host application.
The implementation of this object is optional; the host application can support none, some, or all of the attrib-
utes specified below. The module will attempt to retrieve the values of these attributes during startup; if an at-
tribute is not implemented in the host application, simply respond with an error message (06h, "Invalid
CmdExt[0]"). In such case, the module will use its default value.
If the module attempts to retrieve a value of an attribute not listed below, respond with an error message
(06h, "Invalid CmdExt[0]").
