4.27.2 Commissioning the SM 332; AO 4 x 16 bit
Note
When switching on and off the rated load voltage (L+), wrong intermediate values
can occur across the output for approximately 10 ms.
Parameter
You will find a description of the general procedure for assigning parameters to
analog modules in the reference manual, section 4.7.
You will find an overview of the programmable parameters and their default values
in Table 4-42 in the reference manual.
Assigning parameters to channels
You can configure each output channel of the SM 332; AO 4 x 16 bits individually.
You can thus assign separate parameters for each output channel.
When you set the parameters with SFCs in the user program, the parameters are
assigned to channel groups. Every output channel of the SM 332; AO 4 x 16 bits is
assigned to a channel group in this instance – in other words, for example output
channel 0 = channel group0.
Note
If you modify output ranges when the analog output module SM 332;
AO 4 x 16 bits is in operation, incorrect intermediate values may arise across the
output.
Diagnostics
You will find the diagnostic messages that are grouped under the “group diagnosis”
parameter in Table 4-47 in the reference manual.
