Figure 17: Fast Scanning Mode
In Fast Scanning Mode all devices are active at the
same time. With a start condition at MA the abso-
lute position of all devices is latched and all absolute
positions are transferred as one long data word (see
page 17). Parameter CRCID can be used for improved
differentiation of the individual data words. See ’PRO-
GRAMMING MODE’.
