E.4.8 Link Type - Loop
Link
Type: LoopStart (#, hex 0x23, dec 35)
LoopEnd (-, hex 0x2D, dec 45)
Link
Value: Number of loop iterations
Range: 0 to 65,535
Note: This feature is available only in RMC100 CPU firmware version 19980811 and later.
Note: This link type cannot be used with the Poll (?) command.
The LoopStart (#) and LoopEnd (-) link types are used together to create loops in the Event Step
table. The Link Value of the LoopStart link type indicates how many iterations you want through
the loop. The LoopStart link type jumps immediately to the step indicated by the Link Next. This
should typically indicate the step of the LinkEnd link type.
The LoopEnd link type tests the loop counter to see if it zero. If it is zero then the next step—not
the step specified in the Link Next field—will be executed. If the loop counter is not zero then it is
decremented by one and the step specified in the Link Next field is jumped to. The Link Value on
the LoopEnd link type is ignored and should be set to zero (0).
Example:
The following example executes steps 2 though 5 three times. After the third loop step 7 is executed.
