ABB PLC and drives integration using Modbus RTU
Create a second network (Ctrl +T) in the same program and add the block "ACS_DRIVES_CTRL_STANDARD" in the
same way as for "ACS_COM_MOD_RTU". Connect the function block inputs and outputs according to your needs.
In the example below:

The block will always be enabled

The drive is started by the variable "DriveStart"

Emergency stop functions are not used in this example

Ramp stop by setting "DriveStart" = FALSE

Coast stop by setting "DriveCoastStop" = TRUE

Fault reset by setting "DriveResetFault" = TRUE (positive edge).

Speed reference is set by the variable "SpeedRef" as a value between ‐20000 and 20000, where 20000
corresponds to a parameter in the drive (see chapter "Drive configuration").
The variables declared between "VAR" and "END_VAR" in the picture below are local variables inside this
program. (To access them from another part e.g. any visualization the programs name has to be used followed by
a dot and the variables name. E.g. "Drive1.DriveOperating
Note! The variable connected to "ACS_DRIVES_CTRL_STANDARD" → "DRIVE_DATA" must be the same as the one
connected to "ACS_COM_MOD_RTU" → "DRIVE_DATA" and must be of type "ACS_DRIVE_DATA_TYPE".
