The FB IM308C is shipped together with COM ET 200 Windows on a
3.5 " diskette in MS-DOS format. The file designations are as follows:
Table 9-12 File designations for FB IM308C
File
S5ET50ST.S5D CPU 941 to CPU 944
S5ET55ST.S5D CPU 945
S5ET23ST.S5D CPU 922, 928, CPU 928B
S5ET60ST.S5D CPU 946/947, CPU 948
The diskette also contains a demo program with a description of all the func-
tions of the FB IM308C.
By default, the IM 308-C occupies the address space (F)F800
for addressing distributed I/O. These 512 bytes of address space is the block
also accessed by the FB IM308C. This address space is also required if you
use only linear or page addressing.
Do not change this address space (DP window) unless absolutely necessary,
for example if there is a second IM 308-C in the programmable controller.
You can change the address space in COM ET 200 Windows under the op-
tions for master parameters.
Caution
Danger of double addressing
The IM 308-C uses fully one or more of the address areas shown in Table
9-1 under DP window (default: (F)F800
No part of these address areas may be used by other modules such as CPs,
IPs in the CP area, central I/O in the IM3/IM4 area or the WF 470 position-
sensing module in the central programmable controller.
