Data record 141 reads outs the parameter echoes of the different ASi slaves.
You can evaluate the reactions of the different ASi slaves in a parameter echo
following a “WR_REC” write job in the user program. You thus obtain a cur-
rent image of the state of the ASi slaves. A nibble is assigned to every ASi
slave.
