Structure Of Data Record 141: Read Parameter Echoes Of Asi Slaves - Siemens SIMATIC Distributed I/O System DP/ASi Link Manual

DP/ASi Link to S7
Data record 141 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.
