Read data: 8 bytes
Input area
Addr. Access Assignment
+0 Double word Count value
+4 Word Status word (see the following table)
+6 Word Ticker value
Count value: Current counter content
Ticker value: After mains connection a timer (
ms ticker) is started, which after 65535 ms
starts with 0 again. With every change of the count value the time value of the timer is
stored as 16−bit
ms value together with the count value in the input area.
EPM−S602 status word
Bit Designation Function
0 STS_SYNC Reset was active
1 STS_CTRL_COMP Is set if the comparison bit is enabled
2 STS_SW−GATE Software gate status (set if SW gate active)
3 STS_RST Status of reset input
4 − Reserved
5 STS_GATE Status of internal gate (set if internal gate active)
6 STS_COMP Status of comparison bit
7 STS_C_DN Status set for counter direction backwards
8 STS_C_UP Status set for counter direction forwards
9 STS_CMP* Comparator status is set if the comparison condition is met.
If the comparison is deactivated (counter mode byte 1 = 000
b
), the bit has
no function.
10 STS_END* Status set if final value was reached
11 STS_OFLW* Status set in the case of overflow
12 STS_UFLW* Status set in the case of underflow
13 STS_ZP* Status set in the case of zero crossing
14 − Reserved
15 − Reserved
* The bits are set until reset with RES_SET (bit 6 control word)

+0 Double word Comparison value
+4 Double word Set value
+8 Word Control word (see the following table)
Comparison value: Here you can select a value which, by comparison with the current
counter content, can impact the counter output or trigger a process alarm. The response
of the output or the process alarm can be parameterised.
Set value:With an edge change 0−1 of COUNTERVAL_SET in the control word, the set value
is accepted in the counter.
