ANALOG MEMORY “HOLD” “PEAK” OR “VALLEY”
CONFIGURATION OF MAIN PARAMETERS OF HOLD FUNCTION:
●
Procedure to assign the Analog Memory “Hold” in case it were not activated.
- In
[ConF] [HLd ]
in parameter
[P 02]
check the code
[??nn]
- If this code indicates
[??04]
(not assigned), modify the digits according to the following:
Most common virtual connections to realize the Hold:
Process Variable PV value of AI 1, AI 2, AI 3
[??09], [??10], [??11] respectively
(input
signal)
User Linearization value Lin 1, Lin 2
[??28], [??29] respectively
Integrator value “Int”
[??23] Hi-Output and [??24] Lo-Output
Derivator value “Der 1”, “Der 2”
[??25], [??26] respectively
Counter or Frequency value “DI 2”
[??12] Frequency, [??13] Counter High,
[??14] Counter Low
Arithmetic operator value “Art 1”...”Art 4”
[??30], [??31], [??32], [??33]
respectively
●
Hold Function Operation Mode as Instant, Peak or Valley:
- In
[ConF] [HLd ]
in parameter
[P 03]
modify the digit “n” in
[???n].
- Set
[P 03]
to
[???0]
to select the Peak Hold
- Set
[P 03]
to
[???1]
to select the Valley Hold
- Set
[P 03]
to
[???2]
to select Instant Hold (of the instant the hold order is given)
●
Hold Display Mode in the Main Menu:
Defines in which Loop of the menu or under which Password level, the access to “HLd”
Different options are available:
If it is required only to Hold without displaying the hold value on the main menu, proceed as
follows:
- Set
[P 03]
to
[??0?]
If it is required to display the Hold value in any Loop on the main menu, proceed as follows:
- Set
[P 03]
to
[??1?]
to access from Loop 1
- Set
[P 03]
to
[??2?]
to access from Loop 2
- Set
[P 03]
to
[??3?]
to access from Loop 3
If it is required to display the Hold value under any Password level, proceed as follows:
- Set
[P 03]
to
[??4?]
to access under PASS level 1
- Set
[P 03]
to
[??5?]
to access under PASS level 2
- Set
[P 03]
to
[??6?]
to access under PASS level 3
- Set
[P 03]
to
[??7?]
to access under PASS level 4
According to these configurations, the value of Hold is dispalyed as follows:
