Index
(hex)
00	Bit IO		Table 74	×
01	Mode/Parameter		–	–	–
02	Upper setpoint	SH	In integer range from	×	c1
			–2147483648 to
03	Lower setpoint	SL		×	c1
			+2147483647
04	Preset actual value	SV		×	c1
05	Actual value in Run mode	QV		×
1) The value can only be written if it is assigned to a constant in the program.

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 74: Index 0 – Bit IO

	Bit	7	6	5	4	3	2	1	0
FB input Data 1		–	–	–	–	–	EN1	SE2	RE3
FB output Data 3		–	–	–	–	ZE4	CY5	FB6	OF7

1)Counter enable

2)Transfer preset actual value on rising edge

3)Reset actual value to zero

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

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

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