IP244
C79000–B8576–C866–01
7–12
An IP 244 needs 32 addresses for transferring the necessary parameters. Only
the module’s start address is selected. Internal decoding allocates the next 31
addresses. These addresses are no longer available to other modules. Addres-
ses can be selected in multiples of 32.
The module’s input and output addresses (S5 and S7) must be identical. This is
necessary for correct utilization of the standard function blocks.
In addition, you must enter the following parameters when you configure your
hardware under STEP 7:
– S7 address: a logic address w512 (this address is used for
addressing the module in the application
program)
– S5 address: same as on the module
– Length: 32 bytes
– Partial PA: 0
– Area: depends on the area selected on the module or the
IM 314 (P, Q, IM3 or IM4)
The IP 244 may not lie inside the process map. There are two alternatives to sa-
tisfy this requirement:
select an S7 address w512
select a partial PA value w0
