Adapter Features - Parker H Series Installation & Service Instructions Manual

2-4 What is the H Series Fieldbus DeviceNet Adapter?

Adapter Features

Your adapter uses the following features on both the DeviceNet
network and the PointBus:
• Self-Test
• Field Upgradable Firmware
• Fully Confi gurable Software
• Connections
• Baudrates
Self-Test
When power is applied to the adapter, the adapter performs a self-
test. The adapter tests various internal and programmatic memories
and checks the status indicators (LEDs).
Field Upgradable Firmware
You can update the adapter's fi rmware with the ControlFlash Utility
software. This feature lets you always use the most current fi rmware.
Fully Software Confi gurable
The adapter is fully software confi gurable using RSNetWorx for
DeviceNet. You must confi gure the adapter to be used with a
DeviceNet master (e.g. 1756-DNB) and separately to be used with
Subnet devices.
For more information on how to confi gure your adapter to use with
a DeviceNet master, see Chapter 5, Add the H Series Fieldbus
DeviceNet Adapter to the DeviceNet Scanner's Scanlist.
For more information on how to confi gure your adapter to use with
Subnet modules, see Chapter 4, Confi gure the DeviceNet Scanner
Subnet.
Connections
Your adapter supports the following connections on both the primary
DeviceNet network and Subnet:
• I/O connections:
– Polled
– Strobe
– Cyclic
– COS
• Explicit connections
You can use I/O mapping to determine the data contained in each
connection.
The adapter supports Master/Slave connection types on the
DeviceNet network. On the Subnet, the adapter functions as a
scanner device, exchanging data with I/O modules.

Baudrates
Choose baudrates for the adapter in the RSNetWorx for DeviceNet
software. The adapter supports these rates:
• 125Kbaud
• 250Kbaud
• 500Kbaud
• Autobaud – The adapter detects the primary DeviceNet
network baudrate and automatically sets its own baudrate to
match the network.
• For the PSSCDM12A and PSSCDM18PA, the PointBus can
be confi gured to operate at 1Mbaud (1000Kbaud).
Auto Start Mode
Auto Start Mode lets you easily get your adapter installed and
operating. In this mode, the adapter's confi gurable features operate
as they were most recently confi gured. For example, if Autobaud on
DeviceNet was enabled in the adapter's last confi guration, it will be
enabled when Auto Start Mode is used.
For a more detailed explanation of how to use Auto Start Mode, see
Chapter 3.
Auto Catalog Replace
Auto Catalog Replace corrects errors that might occur when
backplane modules of the same type are removed and replaced in
the wrong location. If modules of the same type are removed and
returned to the wrong locations, the adapter identifi es the returned
modules, updates their MAC IDs, and continues operation.
IMPORTANT
If modules of different types are removed and returned to the
wrong locations, the adapter identifi es the returned modules
and alerts you (via RSNetWorx for DeviceNet, the Node Status
Table, and the Faulted Node Table) that the error has occurred
and must be corrected.
Backplane (PSSCDM12A and PSSCDM18PA) Baudrate
EDS parameter Backplane Baudrate is accessible from the primary
DeviceNet and sets a specifi c baudrate for all backplane I/O modules.
Set this parameter in RSNetWorx for DeviceNet to one of the
following baudrates:
• 125 Kbaud
• 250 Kbaud
• 500 Kbaud
• 1 Mbaud (available for both H Series Fieldbus
DeviceNet adapters)
When you download this parameter, the adapter sends a command
to reset all present I/O modules on the backplane to the new
baudrate. If additional modules are connected to the adapter, you
must download the Backplane/Subnet Baudrate to make sure the
new modules use the same rate as the others.
