Example S7 code CP342-5 (Simatic) --> CI854 (800xA)

OB1 (main)

Call FC130

FC130 (Communicatie met ABB systeem)

FC2 ( DP Receive < 800xA) - DB112.DBX0.0 BYTE 64

FC1 ( DP Send > 800xA) - DB110.DBX0.0 BYTE 64

Make from gsd file > HWL (insert Hardware type)

CP 342-5 (Hardware types)

- 64 bytes DI / Consistency 1 byte (Input 0 - 31, data type DintIO + UnitStatus)

- 64 bytes DO / Consistency 1 byte (Output 0 - 31, data type DintIO + UnitStatus)

Hardware AC 800M

Insert Unit (HW-PB address) CPU342-5, under CI854 (PB-Master)

Insert Unit (HW-1) 64 bytes DI / Consistency 1 byte, under CPU342-5

Insert Unit (HW-2) 64 bytes DO / Consistency 1 byte, under CPU342-5

Single Control Module

Example1 (boolean)

dinttobool16(Int:Registers.diRegisterIn_0x, Bool struct => IDATA1, Status => status);

Example2 (real)

rValue := dint_to_real(Registers.diRegisterIn_0x + Registers.diRegisterIn_0xx);

Registers. (own data type)

diRegisterIn_01 = dint

diRegisterIn_02 = dint

etc....

IDATAx = boolean16

Example HW variable (connection)

IWx.xx.x.0 Input 0 DintIO Application.data-type lib.Registers.diRegisterIn_01

Long time ago I have some troubles with that and I need to swap the signal's of the ABB PLC. You can do that on the GSD wizard tool. Siemens uses a Intel CPU and ABB uses a Motorola CPU. To check it's very easy create a simple counter and check in the hardware diagnostics tool of the both controllers.
