process alarm during a process alarm processing.
Bits 5 ... 0: reserved
Bit 6: diagnostic alarm (0 = inhibited; 1 = enabled)

7 Counter function
counter 1 Bits 5 ... 0:
000000
b
= counting continuously
000001
b
= once: forwards
000010
b
= once: backwards
000100
b
= once: no main counting direction
001000
b
= periodically: forwards
010000
b
= periodically: backwards
100000
b
= periodically: no main counting direction
Bits 7 ... 6: reserved
00
h
8 Comparator
counter 1 Bits 2 ... 0: comparison bit is set (... 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 7 ... 4: reserved
00
h
9 Signal evaluation
counter 1 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)
Bits 6 ... 3: reserved
Bit 7: gate function (internal gate)
0= abort (counting process starts again from loading value)
1 = interrupt (counting process is continued with counter
content)
