Converting S7-200 to S7-1200: SM0.0 SM0.1 and SM0.5

Hi,

In the conversion of a S7-200 program to a S7-1200, the SMs (e.g. SM0.0, SM0.1 and SM0.5) are not converted (stay just as symbolic name, without address). A quick workaround could be given for this case:

In the device configuration, CPU properties, Topic System and clock memory, topic “System and clock memory” enable System memory bits and Clock Memory bits. Choose not used by S7-200 program memory bytes..

In the program, set addresses to not converted SM (based in the open definition):

S7-200 SM0.0 corresponds to S7-1200 variable defined as “Always 1 (high)”
S7-200 SM0.1 corresponds to S7-1200 variable defined as “Always 0 (low)”
S7-200 SM0.5 corresponds to S7-1200 variable defined as “1 Hz clock”

Hi,

In complement to the figure ipcos.jpg, for SM0.0, SM0.1 and SM0.5 you need after the HW configuration just define the simble at ladder like the follow picture:
