Inputs
SH and SL: The upper and lower limit setpoints are set at SH and SL
respectively.
SV: The start value is used to cause the function block to count from a
specified value (Offset).
You can assign the following operands to function block inputs SH,
SL and SV:
•
Constant.
•
Markers MD, MW, MB.
•
Analog inputs IA01 to IA04:
•
IA01: Terminal I7.
•
IA02: Terminal I8.
•
IA03: Terminal I11.
•
IA04: Terminal I12.
•
Analog output QA01.
•
Output
…
QV of a different function block.
Output
QV>: Actual value output CH..QV outputs the current actual value as an
integer. You can assign the following operands to output
…
QV:
•
Analog output QA01.
•
Markers MD, MW, MB.
Retention
High-speed counter relays can be operated with retentive actual values.
The number of retentive counter relays can be selected in the SYSTEM ->
RETENTION menu.
If a meter is retentive, the actual value is retained when the operating mode
changes from RUN to STOP as well as when the supply voltage is switched
off.
If a easy800 is started in RUN mode, the counter operates with the
retentively saved actual value.
→
The actual value can only be cleared in RUN mode with a
specific reset signal.
