Functional Description

6.3.1
The function block "assigning parameters to the positioning module" handles the data exchange
between the user program and the IP247 positioning module. Each valid job number causes a
data transfer IP247 <===> PC.
Data exchange PC ===> IP247:
The data to be transferred is located in a data block of your choice (source DB), With
direct parameter assignment, the data block must be planned at the block parameters of
FBI 65, with indirect parameter assignment, in the axis data block.
Data exchange IP247 ===> PC:
The data to be read from the I P247 positioning module is stored in a data block in the PC
memory (destination DB), With direct parameter assignment, this data block must be
planned at the block parameters of FBI 65 and with indirect parameter assignment in the
axis data block.
The following functions are possible via the PC interface using FBI 65:
— read the SYSID from the IP247 (BA 70) and transfer them to the IP247 (BA 24),
— request an overview of machine data or machining programs stored on the IP247 and
— read actual values (actual position value, distance to go) simultaneously.
The function block FBI 65 can have parameters assigned directly or indirectly. With direct para-
meter assignment, the data and parameters for a job are applied to the parameter inputs of
FBI 65. With indirect parameter assignment, the axis data block is planned in the data block valid
before its call. The remaining parameters are taken by FBI 65 from the axis data block.
Before FBI 65 is called, the axis data block must be set up and with indirect parameter assign-
ment must be supplied with the values required to start the mode.
