Global Output Words
By default, the driver will not transmit global output data until a user application writes to
the global output data buffer. However, the driver can be configured to transmit up to 32
words of global output data even before any application writes to this buffer. Refer to
Peer Cop Communications in the Communication Using the MBX Driver section for more
information.
Health Timeout
The Health Timeout interval specifies the minimum time period that the Peer Cop
configured communication must fail before the associated health bit clears.
The recommended timeout value is 500 msec, which is the default setting.
Global Inputs Configuration
The global input data functionality is identical to the global data functionality that was
available in Modbus Plus prior to Peer Cop. However, Peer Cop provides this functionality
in a more efficient way. For example, global data from multiple nodes can be read in a
single operation.
Note
Up to 32 words of global input data may be requested from each Modbus Plus node
configured here, with the limitation that the total amount of requested data must not
exceed 500 words.
