Byte No.
1 Counter function Bit 5 ... 0:
000000
b
= counting continuously
000001
b
= counting once, main counting direction
forwards
000010
b
= counting once, main counting direction
backwards
000100
b
= counting once, no main counting direction
001000
b
= counting periodically, main counting
direction forwards
010000
b
= counting periodically, main counting
direction backwards
100000
b
= counting periodically, no main counting
direction
Bits 7 ... 6: Reserved
40
h
2 Comparator Bit 2 ... 0: output switches (... if condition is met)
000
b
= never
001
b
= count value ³ comparison value
010
b
= count value £ comparison value
100
b
= count value = comparison value
Bit 3: Invert counting direction track B
0 = no (do not invert)
1 = yes (invert)
Bits 6 ... 4: Reset
000
b
= deactivated
001
b
= HIGH level
011
b
= rising edge
101
b
= rising edge, once
Bit 7: Reserved
00
h
3 Signal evaluation Bits 2 ... 0: Signal evaluation
000
b
= counter deactivated (the other parameter
details for the counter are ignored)
001
b
= rotary transducer single (at A and B)
010
b
= rotary transducer double (at A and B)
011
b
= rotary transducer quadruple (at A and B)
100
b
= direction (pulse at A and direction at B)
Bit 6 ... 3: Hardware gate (HW gate)
000
b
= deactivated (counter starts by setting SW gate)
001
b
= activated (HIGH level at gate activates the HW
gate. Counter starts if HW and SW gate are set.)
Bit 7: Gate function (internal gate)
0= abort (counting process starts again from loading
value)
1 = interrupt (counting process is continued with
counter content)
