Notes

The IP247 positioning module is addressed by means of pages. It has three positioning axes and
a data channel and therefore requires four page addresses.
Function block FBI 64 must be called once for each axis.
Function block FB165 can be called conditionally.
Calls in the processor time interrupt OBS are not permitted.
The function blocks FBI 64 and FBI 65 operate with the data handling blocks SEND and RE-
CEIVE, FB165 also requires the FETCH data handling block.
The handling blocks are (automatically) assigned parameters and called by the FBs. The pages
must beset up in the start-up OB (OB20, OB21 and OB22 or OB21 and OB22 for the S5-1 15U)
with the SYNCHRON data handling block (FB1 25, FB185 and FB249).
