In the case of a cell modem, control is based on time. The modem requires 12 VDC power, so
connect its power wire to a data logger SW12 terminal. The following code snip turns the modem
on for the first ten minutes of every hour using the TimeIsBetween() instruction embedded
in an If/Then logic statement:
If TimeIsBetween (0,10,60,Min)Then
SW12(SW12_1,1,1) 'Turn phone on.
Else
SW12(SW12_1,0,1) 'Turn phone off.
EndIf
