Communication with WCS Read Heads

-0

Description of the protocol data

Byte 1

A1, A0

Address bits of the read head. Addresses 0 ... 3, binary
coding

OVL

The read head is located in the readable area of the
code rail

The read head is located on WCS3 code rail extender
(overlapping area of the code rail segments)

VAL

Position valid

Position invalid; code rail area is not unique after the
supply voltage has been connected

By default, the diagnostic bit is not set

Diagnostic bit, read head dirty

OUT ALL

Read head in code rail

Read head completely outside of the code rail

OUT

Read head in code rail

Read head partially outside the code rail. No valid posi-
tion available

ERR

No error

Error message (possible errors in XP00 ... XP01 binary
coding)

Byte 2 ... 4

XP00 ... XP19

Current position value, binary coding

Byte 5

1. For data protocol with velocity output

SP0 ... SP6

Current speed in 0.1 m/s, binary coding
Example:

•

1: Speed = 0.1 m/s

•

37: Speed = 3.7 m/s

•

112: Speed = 11.2 m/s

SST

Speed valid

Current speed unknown. Last valid speed in
SP0 ... SP6 saved

Byte 5/6

Exclusive or link, byte 1 ... Byte 4/5
