Table 3-1B. Axis 2 (Y) Connection Pins – D32 through D2
Use of I/O address assignments and
function references is described in detail
in Chapter 4 and in the Programming
Reference Manual.
An introduction to I/O and function
reference reassignment is given below.
There are 256 internal I/O addresses.
The first 32 (0 thru 31) are normally
assigned to the front panel default
functions.
A few internal I/O’s serve a fixed
function:
255
Always TRUE (1)
254
Always FALSE (0)
253
Output dummy address
(Output functions assigned to
this address are ignored)
These bit addresses can be used in any
I/O logic equation or for address
assignments. The following describes
how to do this.
In addition to the normal functions
assigned to front panel I/O shown in
Table 3–1A and 3–1B the controller has
several other functions assigned to
internal addresses. These functions can
be accessed externally by re–assigning
the function to a front panel, input or
output.
The FUNCTION list and default
assignment for each axis is shown in
Tables 3-2A and 3-2B.
