1.1
What Can the IM 178-4 Do?
What Can the IM 178-4 Do?
The IM 178-4 is a DP slave with a fixed number of I/Os and has the same design
as S7-300 modules. It has two technologically identical but independent channels
for position detection of incremental position encoders and/or SSI position
encoders and for controlling analog drives (
"
10 V). The module is attached to the
DP network via a 9 pin sub-D male connector.
Per channel, the module has the following:
S
One input for position detection with SSI position encoders or incremental
encoders with 5 V differential signals
S
One analog output
"
10 V
S
3 digital inputs (2 with fixed functions)
S
3 digital outputs that you can use as required.
1.2
Fields of Application of the IM 178-4
Where can you use the IM 178-4?
The IM 178-4 is required mainly by users who want to create distributed position
detection and positioning systems in conjunction with conventional drives with an
analog interface (
"
10 V) and conventional displacement measuring systems (SSI,
incremental position encoders with 5V differential signals). The technological
functionality is no longer in the individual positioning modules as previously but in a
powerful centralized controller.
