Data transfer according to Analog Profile 7.3/7.4

With analog profile 7.3/7.4, at least seven AS-Interface cycles must be passed through before transmission is completed. This requires the use of a master according to Extended Specification V2.1.

With input modules the complete analog value is then available in the AS-Interface master, so that preprocessing is performed in the master.

With the next system function call the user program brings the analog value as one value into the user program. This means that the analog value is updated very quickly.

The analog value transmission applies in reverse order for the output modules as well.

This produces a total of the following maximum times until the analog value with profile 7.3/7.4¹⁾ is available:

1) With presetting: smoothing function deactivated; line filter 50 Hz

Data transfer according to analog profile 7.A.9

With analog profile 7.A.9, only 3 or 4 AS-Interface cycles are required for data transfer. This requires the use of a master that complies with Specification 3.0.

Please refer to the manual for details of maximum times until the analog value with profile 7.A.9 is available, depending on the selected mode (resolution, no. of channels, A/B technology).
