LogicPro User’s Guide Chapter 10: Function Blocks

Doc.# 28002-00 Rev 3.00 Watlow Anafaze 161

A-- is the CAL function’s first argument.

B-- is the CAL function’s second argument.

Outputs

Q-- is the CAL function’s output bit. The output bit is disabled

if the enable bit is False; it is enabled as soon as the input

enable bit becomes True.

C-- is the CAL function’s output destination. If the calculation

to be performed is addition (SYM3=“+”) or multiplication

(SYM3=“*”), and the second symbol is L, the outcome of the

computation will be a double (64-bit) integer.

NOTE! InterLock, InterLock Clear, and Jump Function

blocks are not available in FBD programs.

Jump (JMP)

symbol1 = JMP

The Jump (JMP) function block, shown in Figure 10.42,

performs a GOTO <LABEL> action. This function block needs

to be positioned at the end of a rung. Labels can be set at rungs

throughout the Ladder Diagram by clicking on the rung

number in the workspace. Infinite loops cause errors which

can be detected by scan-time monitoring.

Figure 10.42 The Jump Function Block

Inputs

EN-- is the Jump enable bit.

LB-- is the Label of the rung to which the function block points

and passes control to in a GOTO-like fashion.

See “Assigning Labels to Rungs” on page 100 for

information on labeling rungs.

Output

Q-- is the output Jump function block’s output bit. Its value is

always equal to that of the enable bit EN.
