Smb200 To Smb549: Intelligent Module Status - Siemens SIMATIC S7-200 System Manual

SMB200 to SMB549: Intelligent Module Status

As shown in Table D-20, SMB200 through SMB549 are reserved for information provided by
intelligent expansion modules, such as the EM 277 PROFIBUS--DP module. For information
about how your module uses SMB200 through SMB549, refer to Appendix A for the specifications
of your specific module.
For an S7-200 CPU with firmware prior to version 1.2, you must install the intelligent module next
to the CPU in order to ensure compatibility.
