TrueBlend™ Operation
Edition: February 2008 109
connected using an ethernet switch and straight through ethernet cables. See
your computer technical help for assistance on setting up a network like this.
When blenders are connected together, the last three digits of the ethernet IP
address (Home > Settings > Panel setup > IP address) must be unique for each
blender.
The loading control for an individual blender is divided up into three
separate functions as shown here:
• Loading control
• Waiting list (a first in, first out queue)
•
Blower control
When a loader needs material, it’s demand switch will turn on. When the
loading control sees the demand switch input, it sends a message to the
waiting list. The waiting list queues the loader’s requests in a list. When the
blower is available the waiting list then sends a message to the blower control,
which operates to satisfy the loader. The connections between the three
functions may be configured by the user at the service level. These connections
are specified in the loader setting’s screen and the blower setting’s screen. The
following examples illustrate how to configure these variables.
Example 1
In this example two blenders will be sharing a conveying blower. There is a
direct connection between the two blenders with an ethernet crossover cable.
Blender 1
Blender 1 is physically connected to the conveying blower. The blender
has an ethernet address of 192.168.3.249 (default address).
Blender 2
Blender 2 has no physical blower connected. It will use the conveying
blower on blender 1. The blender has an ethernet address of
192.168.3.240 (address changed from default). Refer to section 7.16
“Panel setup” screen to change IP address from default.
