Description
Specify relays to close.
Set Isrc to 50mA for M2; since this source level is
the same as that set in the Initial Setup subroutine,
this command can be left out.
Set Memory Delay = 0.
Select DC volts measurement function.
Select 100mV fixed measurement range.
Set A/D integration time to 1 PLC.
Enable measurement during scan; during a scan the
measurement is initiated automatically. This does
not apply when a memory pattern is recalled as
shown below. In the latter case, the reading must be
initiated explicitly as also shown below.
Specify relays to close.
Set Isrc to 50mA for M3; since this source level is
the same as that set in the Initial Setup subroutine,
this command can be left out.
Note: You do not need to keep setting sources if they
do not change.
Set Memory Delay = 0.
Set A/D integration time to 1 PLC.
Select S1IOHMS math function; selecting this
function automatically selects DCV measurement
function and the 1V measurement range.
Enable the math function.
Enable measurement during scan; during a scan the
measurement is initiated automatically. This does
not apply when a memory pattern is recalled as
shown below. In the latter case, the reading must be
initiated explicitly as also shown below.
