The following comments in the network are also affected, even when the exchanged parameters are not even commented. In the worst case comments might even be lost. When the block is opened, the comments are then assigned incorrectly. Thus, when exchanging parameters in the source, the order of comments might then be wrong. The comments, however, are stored separately from the actual online block in the order entered. The parameter assignments can be specified in any order in the ASCII source. The output variable of the higher-level block, the static variable and the input variable of the lower-level block must be of the same data type.
In a further network this static variable is parameterized with the IN variable of the FB called. We recommend first saving the data temporarily on a static variable. It is not allowed, that an OUT variable of the calling function block is parameterized with the IN variable of the function block called. The declaration range of your formal parameter does not match the declaration range of the actual parameter, for example, no OUTPUT paramater from the actual end can be assigned to an INPUT parameter from the formal end. The block named is protected and cannot be generated into an STL source. You are trying to generate a KNOW_HOW_PROTECT block into an STL source. The block %4 that was called/used is protected or created by S7-GRAPH and cannot be generated. If the SFB/SFC is not available on the CPU addressed, then it should not be
In the case of SFB/SFC calls, please copy into your offline database with the The block is to be compiled before the call.

This is no longer permitted with Step7 V5.0. With Step7 V5.0 the instance DB of the DB type is entered in the symbol list for an FB call. Block call invalid because interface was changed in the meantime.
