Scaling for EtherNet/IP Devices
Scaling is handled in the following ways for EtherNet/IP devices:
• The assembly being referenced in the connection manager is for the O->T and
T->O is scanned for the presence of the scaling parameter.
• The information of the scanned parameter is then used as the scaling parameter
for all the channels that are created from that particular assembly.
• The scaling is done for both the input and output channels.
Specifying Status and Signal Range Parameters for Channels
The Status parameters and Signal Range parameters are set in the Advanced settings
with status window, while configuring input and output areas for analog and digital
channels.
For digital channels, only Status parameters can be defined. For analog channels
input area configuration, both Status and Signal Range parameters can be defined.
For analog channels output area configuration, only Signal Range parameters can be
defined.
Status Parameter
Status Parameter is set by defining a status bit for a channel. This status bit indicates
the status of the channel – whether the channel data is in correct or in corrupted
state. The status bit hence determines whether or not the channel data is fit to be
transferred from the controller to the application.
For a particular connection type, select the status bit for a parameter from the
available input/output bits only. Select the status bit for a particular channel
according to the instructions present in the Device manual. If a bit is selected as a
status bit for a particular channel, then the bit cannot be used again for channel data
in the same connection type. The bits selected as status bits cannot be assigned
again to other channels either. Refer the following example for better understanding.
Assume there is 1byte to indicate a connection. This means that there are only 8 bits
to both define the channels and specify the status of those channels. In such a case,
for 1Byte of data the status bits can be set as illustrated in Figure 45.
