Assigned System Marker Area (SM Area)
The CP 243-1 IT occupies 50 bytes in the system marker area of the S7-200 CPU.
The address of these 50 bytes depends on the current position a CP 243-1 IT oc-
cupies in an S7-200 system. These 50 bytes primarily contain general information
and status information of the CP 243-1 IT. The last four bytes contain a pointer with
which the configuration data of the CP 243-1 IT can be accessed. These configura-
tion data are located consecutively in the variable memory of the S7-200 CPU.
These data are divided into the following data blocks.
•
Configuration Data Block (CDB)
•
Network Parameter Block (NPB)
•
Network Data Block (NDB)
•
Internet Data Block (IDB)
