Libraries
Note
STEP 7-Micro/WIN program code generated by *.mwl files (compiled libraries) is not
converted.
This includes subroutines, interrupt routines, V memory data, and symbol definitions. You
must create substitute program logic.
The STEP 7-Micro/WIN *.mwp program file is converted. The *.mwp file is the program
source file for regular user programs and for user-created libraries. You must use STEP 7
Basic library commands to create a STEP 7 Basic global or project library from a converted
STEP 7-Micro/WIN library source program.

S7-1200 programming
S7-200 Internet module operations such as FTP Server, FTP Client, Email,
and User IDs are not supported by firmware in the initial S7-1200 CPU
release.
PPI network communication instructions are replaced by Ethernet T-block
(TSEND_C. TRCV_C) peer-to-peer communication instructions.
S7-200 PID operation can be programmed directly with the PID instruction or
indirectly through the PID wizard.
S7-1200 PID operation uses the PID technology object and the PID_Compact
instruction available in STEP 7 Basic. A S7-200 program call to a PIDx_INIT
subroutine or a PID instruction must be replaced with the S7-1200
PID_Compact instruction. PID_Compact operating parameters are not
converted and must be assigned and initialized by you.
A S7-200 program call to a PWMx_RUN subroutine is converted to the S7-
1200 CTRL_PWM instruction. You must assign new pulse control parameters
and initialize the parameter values within the converted program. Pulse
generator operation parameters must be set in the STEP 7 Basic PLC device
configuration, before a program can use the pulse generators.
This feature is not supported in the STEP 7 Basic V10.5 SP2 release.
The TD panels supported by the STEP 7-Micro/WIN text display wizard are
not supported by the S7-1200. You must rewrite this program section to
operate a STEP 7 HMI Basic panel through an Ethernet connection.
