1) The value can only be written if it is assigned to a constant in the program.

J

The data for index 2 to 5 is transferred as a 32-bit value in Intel format (Data 1 – Low Byte to Data 4 – High Byte).

Table 68: Index 0: Bit IO

	Bit	7	6	5	4	3	2	1	0
FB input Data 1		–	–	–	–	SE1	D2	C3	RE4
FB output Data 3		–	–	–	–	ZE5	CY6	FB7	OF8

1)Transfer preset actual value on rising edge

2)Count direction: 0 = up counting, 1 = down counting

3)Count coil, counts on every rising edge

4)Reset actual value to zero

5)Zero: Status 1 if the value of the function block output QV (the counter status) equals zero

6)Carry: Status 1 if the value range is exceeded

7)	Fall below: Status 1 if the actual value	lower setpoint
8)	Overflow: Status 1 if the actual value	upper setpoint
