Programming Instructions
9.5.12 Inhibit Interrupt Depending on Direction
This function requires that the desired interrupts have been enabled in user data block DB 156
during startup. The desired inhibit direction must first be stored in data word DW 186 of user data
block FB 156 before this function can be activated with input 15.3.
DB 156
DW 186 KM = 0000000000000001
This special function requires two parameters each which must be supplied in user data block DB
156, These parameters are "channel no." and "number". The "channel no." parameter is used to
select channel 1 with the value zero, and channel 2 with the value 16. The supply range of the
"number" parameter is between zero and 15, and classifies the range of activity of the special func-
tion.
The parameters of the desired special function are transferred to the module by setting input 15.1
for "verify–read" and 15.2 for "calculate average value".
