Instructions
Analyzer Power
The quality of the analyzer power is impor-
tant. It must be within a couple of volts of
24 V, and it must be reasonably quiet. 100
mV of noise is adequate. Earlier analyzers
required inrush current limiting if the leads
supplying power were longer than a couple
of feet. Later analyzers (with the CE mark)
were not as touchy. If such protection was
not provided, the analyzers might blow
fuses upon start up. In this case, replace
the fuse and try again. Don't plug in the
analyzer power while it is turned on.
Naming Analyzers
Verify the I/O modules are named appropri-
ately. You want to be able to tell which I/O
module is which, so you can bind it to the
appropriate analyzer. The variable TAG is
used for this. Later I/O modules are able to
tell which slot they are plugged into on the
control module Backplane, but most I/O
modules cannot do this, and so they rely on
your knowing which one they are in some
other way.
An easy way to do this is as follows:
Plug the I/O modules into the platform one
by one. Do this with no analyzers con-
nected.
Power up the Platform.
Press the button marked "RE-INIT" as the
control module initializes itself.
When it is showing its main display, press
the button marked "MENUS".
Select
Technical level configuration...
In the resulting menu, select
Listing of all
modules...
Select the listed I/O module.
On the bottom line of the resulting menu
edit the I/O module tag to something that
you will recognize.
Do this for each I/O module in turn. Then
reconnect the whole system, including the
analyzers, and again press the “RE-INIT”
button.
