5.10.2.2.1 ENERGY TAGS
The following tags are available for energy management:
REM1: Energy tags are logged after each new period IF Logging is enabled, even if the value has not changed since previous period.
REM2: Even if Deadband is -1 and Interval is 0. If not, you will have additional points and even maybe duplicate points.
(*) Important: See “Tags are stored as Float” on page 67
5.10.2.2.2 32 BIT COUNTER TAGS:
The eWON IO Server provides now 8 32 bits (*) counter tags named: CI1..CI8. These counters are writable but writing in these registers affects
the LIx inputs of the Energy IO server module.
(*) Important: See “Tags are stored as Float” on page 67
LI1..LI8 Latched input
When the Integration Period expires, the number of pulses counted during the integration
period are logged in the corresponding LIx.
ST1..ST4 Status variables:
ST1 This is the absolute time when counter were latched.
Expressed in seconds since 1/1/1970 minus 0x30000000 HEX (or 805306368 decimal).
This huge value is substracted to maintain precision in the Float storage. (*)
Latch time - 0x30000000
ST2
0 means period is valid (within tolerance), 1 means period is invalid.
Period status
ST3
Length of the period in second.
Period length sec
ST4
This 32 bit counter counts is increased by 1 after each integration period. It can be used with
ONCHANGE to perform operations when period expires.
