Due to supply issues with the S7-1214C PLC, referenced in the supplied curriculum materials, it has been necessary to ship alternate S7-1212C PLCs with some orders.
The plant control sample file (ZAP file) supplied in the curriculum materials will not work with these PLCs. It is possible to select each of the PLCs and use the "Change Device" option to specify the correct S7-1212C DC/DC/DC PLC.
Alternatively you can download the adapted sample file below.
