6. Configuration

6. 3. Communication scanner

The communication scanner enables all the application-relevant parameters to be grouped in 2 consecutive word tables so that single read and write operations may be performed. It is even possible to perform a single transaction using the "Read/Write Multiple Registers" (23 = 16#17) function.

The 8 output variables are assigned using the 8 [Scan.Outp address] (nCAp) parameters. They are configured using the graphic display terminal via the [1.9 - COMMUNICATION] (COM-)menu, [COM. SCANNER OUTPUT] (OCS-)submenu.

The 8 input variables are assigned using the 8 [Scan. INp address] (nMAp) parameters. They are configured using the graphic display terminal via the [1.9 - COMMUNICATION] (COM-)menu, [COM. SCANNER INPUT] (ICS-)submenu.

Enter the logic address of the parameter (see the Parameters Manual).

If a [Scan.Outp address] (nCAp) or [Scan. INp address] (nMAp) parameter equals zero, the corresponding variable is not used by the drive.

These 16 assignment parameters are described in the tables below:

Note:

Any modification to parameters [Scan.Outp address] (nCAp) or [Scan. INp address] (nMAp) must be made with the motor stopped. The master PLC program should be updated to take account of this modification.
