Programming Instructions
When the “calculate average value” or “verify” special function is used, the “number” para-meter
must be located in the range from O to 15 in data word
DR 184 or DR 182 respectively in the user
data block. When zero is entered, the function switches off. Supplying the “channel no.” parame-
ter in data word DL 184 or DL 182 of the user data block is not necessary. This parameter is only
used in cyclic operation with function blocks FB 157 and FB 158.
After the processing of function block FB 156, the data block which was valid prior to calling
FB 156 remains valid. The user data block with the setpoints is called by the function block FB 156
automatically.
(KH = 1234 in data word DW 3) when the transfer of parameters is complete.
