The double word for the counter mode has the following structure:
Byte Bit 7 ... 0
0 n Bit 2 ... 0: Signal evaluation
–
000b = Counter de-activated
At de-activated counter the further parameter settings for this counter
are ignored and the according I/O channel is set as "normal" output if
this should be used as output.
– 001b = Encoder 1-tier (at counter
X
(A
X
) and counter
X
(B
X
))
– 010b = Encoder 2-tier (at counter
X
(A
X
) and counter
X
(B
X
))
– 011b = Encoder 4-tier (at counter
X
(A
X
) and counter
X
(B
X
))
– 100b = Pulse/direction (pulse at counter
X
(A
X
) and direction at
counter
X
(B
X
))
n Bit 6 ... 3: C
X
Input (function of the counter input as gate, latch or reset)
– 0000b = de-activated (counter starts at set SW gate)
– 0001b = Gate
X
The input of counter
X
serves as gate. High level at gate activates the
HW gate. The counter may only start when HW and SW gate are set.
– 0010b = Monoflop *
– 0100b = Latch
X
(edge 0-1 at input saves counter value of counter
X
)
– 1000b = Reset
X
(positive level at input resets counter
X
)
n Bit 7: Gate function (internal gate)
–
0 = abort (count process starts again at load value)
– 1 = interrupt (count process continues with counter value)
1 n Bit 2 ... 0: Output set
(OUT
X
of counter
X
is set when condition is met)
– 000b = never
– 001b = counter value
³
comparison value
– 010b = counter value
£
comparison value
– 100b = counter value = comparison value
n Bit 3: Count direction
–
0 = Count direction inverted: OFF (count direction at B
X
not inverted)
– 1 = Count direction inverted: ON (count direction at B
X
inverted)
n Bit 7 ... 4: reserved
2 n Bit 5 ... 0: Counter function

– 000000b = count endless
– 000001b = once: forward
– 000010b = once: backwards
– 000100b = once: no main direction
– 001000b = periodic: forward
– 010000b = periodic: backwards
– 100000b = periodic: no main direction
n Bit 7 ... 6: C
X
In-/Output
(Function of the counter I/O as OUT, Latch or Reset)
–
00b = O: OUT
X
(at comparison function)
– 01b = I: Latch
X
(edge 0-1 saves counter value of counter
X
)
– 10b = I: Reset
X
(Positive level resets counter
X
)
