4.31.1 Commissioning the SM 334; AI 4/AO 2 x 12 bits
Note
Below the rated load voltage range, incorrect intermediate values occur at the
output when the rated load voltage supply (L+) is switched on/off.
STEP 7 V 4.0 tool for parameter assignment
The SM 334; AI 4/AO 2 x 12 bits is contained in the module catalog in STEP 7
V 4.0 or higher.
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in Section 4.7.
You will find an overview of the programmable parameters and their default values
in Table 4-43, on page 4-44.
4.31.2 Measuring/output method and measuring/output range of the
SM 334; AI 4/AO 2 x 12 bits
Connecting the inputs and outputs
You can connect the inputs as voltage, resistance or temperature measurement
inputs, or deactivate them.
You can connect the outputs as voltage, or disable them.
Perform connection of the inputs and outputs with the parameters “measuring
method” and “output method” in STEP 7.
Connection options for the input channels
You can connect the SM 334; AI 4/AO 2 x 12 bits in the following combinations:
