Starting up fieldbus communication and programming the ABB PLC (one-drive system)

8. In this section a new program row is made before the access_axis1 block. This is

because the state of input switches Off1, Off2 and Off3 must be TRUE before

starting block access_axis1 when the program is run.

Right-click somewhere in the blank area to open the following menu and select

Network (before). -> A new programmable area (program row 0001) is made.

The switches have to go to the TRUE state in the following order: Off2, Off3 and

Off1. They cannot turn on immediately, one after another, so add delay function

blocks (TON) with a delay time of 200 ms.

In case of errors, output ERR_REMOTE has to be evaluated before start. This is

done by block AND with an inverted input. To invert the input, right-click on the input

and select Negate.

Off1_3 is a switch which is later used starting the drive when the program is run. It

is a global variable (Class: VAR_GLOBAL; Type: BOOL).
