Parameter Transfer Using Digital Input Modules

In this example, the parameters for the positioning job are transferred to the PIQ
using digital input modules. The complete output message frame is to be
transferred to the PIQ in one scan. If this principle cannot be followed, it is
important to transfer the "Forwards" or "Backwards" mode to the IP 267 as the
last parameter of the output message frame in the case of preset positioning
jobs, as otherwise the IP 267 will start the positioning job immediately, i.e. with
an old velocity factor or a wrong path.
