There is nothing to configure for the digital modules, but the analog module channels
need to be configured for the analog type. Select the analog module and below it will be
displayed the variables available for it in the Logic Engine. The Average values are the
analog input signals averaged over a default of 10 samples. The other values for the
analog inputs are instantaneous values. The status for the module is also provided.
Also, in the Properties window for this analog module are the
selections for the analog type for each I/O channel as well as
optional sample counts for average input values. There is a
scale function block (REFSCALE) in the Logic Engine for
scaling analog values. The “AVGNum“ or average number
values are the number of samples used for the average
analog input values to smooth out the signals. The default is
10 and if used, nothing needs to be entered for these
parameters.
Selecting the down arrows to the right of CH1Mode through
CH6Mode allows the selection for the analog type for each
analog input and output. For this analog combination input
and output module, CH1 through CH4 are the inputs and
CH5 and CH6 are the analog outputs.
Analog input mode selections:
–10 Vdc to +10 Vdc
–6 Vdc to +10 Vdc
–12 mA to +20 mA
–20 mA to +20 mA
Analog output mode selections:
0 Vdc to +10 Vdc
+2 Vdc to +10 Vdc
+4 mA to +20 mA
0 mA to +20 mA
Refer to the Instruction Leaflet for each analog module,
thermocouple module and RTD module for the decimal range
for each input or output type and specifications and wiring.
