struction of optical PROFIBUS DP networks for indoor applications.
Plastic fiberoptic cables are easy to assemble on-site with
2 x 2 simplex connectors. The maximum cable length between
two DP devices is 50 m.

Using SIMATIC PCS 7, plastic fiberoptic cables are an alterna- lengths up to 50 m
tive for automation system connections of ET 200M with only failsafe
I/O modules when compliance with SIL 3 is demanded for
the failsafe application. Plastic fiberoptic cables are then used to
connect the ET 200Ms through Optical Bus Terminals (OBT) to
the electrical bus cable of the PROFIBUS DP. The advantage of
this configuration is that it eliminates the disconnecting module
for decoupling the signal between the IM and the failsafe mod-
