Monitor Block Display for a High-speed Counter Block
For a High-speed Counter block, the Monitor
Block function displays a sequence of screens with
the following information:
1. The states of the block’s four Preset Outputs.
2. The states of the block’s Control Inputs.
3. The current values of the block’s internal data
storage registers: Accumulator, Counts per
Timebase, and Strobe.
The exact appearance and sequence of screens
depends upon whether the block has been set up
for four-counter (Type A), two-counter (Type B), or
one-counter (Type C) operation. The letter a, b, or
c on the top line of the screen shows how the
block is set up.

Preset Outputs

First, the Preset Outputs are displayed:
R E F (ctrnumber) (ctrtype)
PRESET OUTPUT
1234
OOOO
Outputs that are forced are shown with an
underscore (forced outputs do NOT respond to
the actual value of the counter).

Control Inputs

Press F1 ( > ) to display the block’s Control Inputs:
CONTROL INPUTS c
1112123
DHPPSSS
111111O
On this screen, the numbers on line 2 identify the
first, second, third, of fourth control input of the
same input type on the block. The third line
identifies the input type: Disable Input (D), Home
Input (H), Preload Input(P), or Strobe Input (S).
The screen’s bottom line shows the current state of
each Control Input.

Register Values

Press F1 ( > ) to display the current value in each
counter’s accumulator, Counts-per-Timebase
register, and Strobe register(s):
R E F (number)(countertype)
ACC 1:_+(acc.value)
CTB 1:_+(countvalue)
> nxt
Use the F1 ( > ) key to display the strobe value(s),
and additional values appropriate to the counter
type. For more detailed instructions for using a
Hand-held Monitor with a High-speed Counter,
