Creating a program code to control the device
8.8 Creating a program code to control the device

1. Create the program code to control the field device. The device must be used in the
program code so that the SDO initialisation can take place.
If you insert more devices in the control configuration, the addresses of the
existing % variables may change. Thus, do not use any % variables directly in the
program code but allocate separate names:
2. Compile the program and transfer it to the control system.
8.8.1 Special features of the Servo Drives 9400
 When the program starts, the control initialises the Servo Drive 9400. The controller
changes to the "Operational" state.
8.8.2 Special features of the Inverter Drives 8400
 When the program starts, the control initialises the Inverter Drive 8400. The frequency
inverter changes to the "Operational" state.

Note!
All program blocks which are operated with an SDO communication must be
called up in a Logic task. Otherwise, jobs will get lost.
