F3--04DAS 4-Channel Isolated Analog Output
Module Operation
Before you begin writing the control program, it is important to take a few minutes to
understand how the module processes and represents the analog signals.
The F3--04DAS module can update one channel per CPU scan. Your RLL program
selects the channel to update, so you have complete flexibility in solving your
application requirements.
