Sample program

Sample program: slave diagnostics echo (parameter echo). The standard function ASi_3422

(FC7) of the AS-i master (PROFIBUS-ASi) is used for this purpose.

For a description of the block, refer to the manual for the AS-i master (DP-ASi Link, CP343-

2). This also describes the call interfaces and commands.

Block ASi_3422 must be called up once when the system is rebooted (OB100).

Call in OB100:

CALL "ASi_3422"

ACT :=FALSE

ACT :=FALSE // not required

STARTUP:=TRUE

LADDR :=W#16#14 // I / O address AS-i master

SEND := P#M 4.0 BYTE 1 // irrelevant

RECV := P#M 4.0 BYTE 1 // irrelevant

DONE :=M19.2

ERROR :=M19.3

STATUS :=MD24

To read the parameter echo, the "Write_Parameter" command must be sent to the M200D

AS-i Basic motor starter.
