11.12 Calculators (calculation modules)
Description
Both the "Calculator 1" and "Calculator 2" logic modules integrated in basic
unit 2 contain the standard calculation modes and enable all analog values
that occur in SIMOCODE pro to be adapted, calculated and converted, e.g.
• Conversion of the measured temperatures from K (Kelvin) to °F or °C
• Conversion of the motor current from [%] to [A]
• Conversion of the 0/4 - 20 mA signals of the analog module directly into fill
levels, pressures and flow rates.
The analog value (2 bytes/1 word) present at the analog sockets is
calculated using a defined formula and using freely-selectable parameters
(counters, denominators, operators, offsets). The result of the calculation is
output as an analog value at the analog socket of the logic module
(2 bytes/1 word) for further processing.
Each calculator consists of:
• One analog plug (calculator 1) or two analog plugs (calculator 2)
• One logic component
• One analog socket.
