  1. Twincat PLC - how declare variable

    I'm new in PLC programming.  I have a small project which have 15 temperature sensor.  How I should declare the variable for this 15 sensor.   I try code below temp0 AT %IW10: INT;     temp1 AT %IW12:INT; I also have 15 controller which use to control the temperature.  How I should declare this 15 controller also?      
  2. Twincat PLC - how declare variable

    Means I no need declare one by one, just declare temp0 AT %I*: INT, then during linked time, all my IOs can link to same variable?
