Hi, Module drivers are basically the interaction between IO modules and your CFC program. When you check the: "Generate module drivers" option, CFC system charts are generated which are indicated by a "@" in front of the CFC name. Those charts contain blocks which interact with IO and CFC program, like transferring the correct Mode setting (if it is pt100 or 4 channel input or rtd) and diagnostic info like channel breaks and such. The input and output drivers like PCS7AnIn are used on the CFC program side to interact with the IO. Beware that you must use released modules for your PCS7 version, according to the released modules document or better and faster; the hardware catalog with "PCS7 Vx" profile selected. This allows you to use only modules which are supported by your PCS7 version. It is very well possible to not use the module drivers. In this case, you must set the input or output drivers to the correct mode yourself in order to not receive a Bad signal. Since PCS7 v8.x, the generate module driver option is always checked during a compile. So, its best to leave this on, otherwise you have to deselect every time which is not foul proof. Before v8.x, it was possible to have option be deselected during every next compile. I hope this answers your question! |
