7.10 Command #50 Read Dynamic Variables Assignments
The possible mappings of Transmitter Variables into array of Dynamic Variables are already discussed in section 5.1,
Inputs/Outputs and Dynamic/Transmitter Variables. On startup Dynamic Variables are configured as follows:
Primary Variable Code = 1, SmoothedFlow; permanent setting.
Secondary Variable Code = 0, RawFlow, or 1, SmoothedFlow, depending on the value of device variable
TimeConstantControl (Menu 1.2), correspondingly Only I or All; variable setting.
Tertiary Variable Code = 2, PositiveTotalizer; variable setting.
Fourth Variable Code = 3, NegativeTotalizer; variable setting.
NOTE: Settings for Tertiary and Fourth Variables correspond to logical slots (not analog outputs) and therefore are
stored in RAM. Hence any external changes in TV, QV code values will be actual until the first power-on or device-
initiated reset.
