5 Programming
Use STEP 7 Micro/WIN 32 to develop S7-200 user programs. For you to be able to
use the CP 243-1 functions in these programs, the STEP 7 Micro/WIN 32 you use
must be version V3.2.1 or higher.
To be able to operate the CP 243-1 as a client or as a server, at least one of the
communications channels of the CP 243-1 must be configured accordingly. In addi-
tion, the S7-200 user program must also be programmed accordingly.
The CP 243-1 is programmed in the S7-200 user program in the following subrou-
tines, where the position in which a CP 243-1 is located in the S7-200 system is in-
cluded in the name of the subroutine:
• ETHx_CTRL
• ETHx_CFG
• ETHx_XFR
These subroutines are generated by the Ethernet Wizard integrated in STEP 7 Mi-
cro/WIN 32 when configuration is completed. You will then find these subroutines
in STEP 7 Micro/WIN 32 in the window in the operation tree under the "Subpro-
gram calls" entry. Which subroutines are generated by the Wizard when configura-
tion is completed depends on the data that you specified during configuration.
Attention
These subroutines may not be called up in the S7-200 user program by interrupt
routines.
