Communication with WCS Read Heads
5.2 Option-E
—
Extended, Type WCS3B-LS2*E*, RS-485
The read head WCS3-Extended: WCS3B-LS*E* with RS-485 interface is used for routes of
more than 314.573 m. In this case, the additional "E" in the type code identifies the extended
version for the extending code rail. Two standard code rail segments with a length of
0 ... 314.573 m are connected to each other with the WCS3-CS70-E code rail extender to
achieve a maximum code rail length of up to 629.146 m. The first code rail segment must
always be complete, or end with the position at 314.573 m. The second code rail segment can
have a shorter length of 314.573 m to X m, but must be used in descending position, starting at
314.573 m.
