PS-5000 Series PLμS controls containing the "F" option
can store approximately four times as many output pulses
(approximately 4500 pulses) in permanent memory as
standard PS-5000 Series controls. The exact number of
pulses that can be stored will vary between different models
and features included.
An "F" option control can store as many as 992 different
setpoint programs. Unlike other PLμS controls, a special
"Pn" (program number) feature included in "F" controls
allows direct access to any program by entering its 3-digit
value. Also, the current active program number is displayed
during normal operation as shown below.
Number of Pulses/Programs Available
The actual number of different programs that can be
entered is determined by the total number of pulses that
can be stored (approx. 4500) and the number of pulses
needed for each program.
For example, if 14 outputs are being used and each output
has 1 pulse per machine cycle, the total number of programs
that could be stored would be:
4500 total pulses (approx)
14 pulses per program
The current active program will always be displayed while
RPM is displayed as shown below.

5-4 Programming, Optional Features
Special Alternate Functions have been included in the "F"
option to report the total number of pulses that can be
stored, and how many are currently programmed. See
page A-16 for directions on accessing alternate functions.
ALT FCN 1010 displays exact total number of pulses
available.
ALT FCN 1011 displays number of pulses presently
programmed.
Pulses Remaining = ALT FCN 1010 minus ALT FCN 1011
!! WARNING !!
PLμS controls continuously calculate a checksum value
which represents all of the programmed contents in the
permanent memory. The control power must remain on
a minimum of five seconds after any programming
change is made to insure that the new checksum has
been calculated.
If power is turned off before the checksum is calcu-
lated, the control will have to check the validity of all
programmed contents on the next power-up. This
will take approximately 18-20 minutes. The control
will not be able to run the machine during this time.
The current active program will be displayed while position
(POS) is displayed (shown below) if neither of the following
two conditions exist:
1. An output channel is selected.
2. The control is a PS-5XX4 with more than 1 output group
established.
