Product Overview

C79000-G7076-C178-01
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:
SOne input for position detection with SSI position encoders or incremental
encoders with 5 V differential signals
SOne analog output "10 V
S3 digital inputs (2 with fixed functions)
S3 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.
