Description
The JMP_LIST instruction acts as a program jump distributor to control
0: GOTO dest0;
the execution of program sections. Depending on the value of the K
1: GOTO dest1;
input, a jump occurs to the corresponding program label. Program
execution continues with the program instructions that follow the
2: GOTO dest2;
destination jump label. If the value of the K input exceeds the number of
[n: GOTO destn;]
labels - 1, then no jump occurs and processing continues with the next
program network.
Description
Jump distributor control value
Jump destination labels corresponding to specific K parameter values:
If the value of K equals 0, then a jump occurs to the program label
assigned to the DEST0 output. If the value of K equals 1, then a jump
occurs to the program label assigned to the DEST1 output, and so on. If
the value of the K input exceeds the (number of labels - 1), then no jump
occurs and processing continues with the next program network.
