A Brief Introduction to the IP247

2.2 A Brief Introduction to the IP247
Using the positioning module IP247, you can move and position three independent axes. From
the positioning jobs and the machine data, the module calculates pulse trains which are output
to the connected stepper motor power unit, The number of pulses decides the distance travelled,
the pulse frequency corresponds to the speed, A direction signal is also output to
of
direction the movement,

Due to its adaptability, the module must have parameters assigned to it. Parameter assignment
is simple and is performed at the monitor of a programmer (PG) using the software package
user-friendly support of the COM247 software package,
In the test mode, the COM247 software package allows you to test all the functions of the IP247
and therefore the positioning functions of your plant.
Two standard function blocks FBI 64 and FBI 65 are used to incorporate the functions of the
These are stored in an EPROM cartridge in the CPU. The data handling blocks for communica-
tions processors are subordinate to the function blocks.
The module can be operated both from a PG and from a PC, however, the functions of the inter-
faces differ from each other. With the software package COM247, the PG is used for convenient
parameter assignment, starting up and testing the module. The PC interface is used to execute
the functions of the IP247 during normal plant operation.
