M172P* JMP instruction

[obscuresc]

Hi,

I am looking at using a JMP instruction in Structured Text for handling fatal errors in my application; I would like to be able to jump forward between programs to avoid standard routines.

Below I am testing the syntax with respect to the path in the ESME HVAC Help documentation

EcoStruxure Machine Expert HVAC > Software > Ecostruxure Machine Expert - HVAC - Operating Guide > Programming > Language Reference > Common Elements > Operator and Standard Blocks

Spoiler

JMP label;
label : cnt := cnt + 1;

All I receive is

MAIN(1) - error S1312: label => Syntax error

This appears to be the same as syntax of other platforms (i.e. CodeSYS, Beckhoff).

I am using EcoStruxure Machine Expert HVAC v1.6.0.

What am I doing wrong?

Cheers.

Hi,

JMP is not supported on ST language (I will ask to improve documentation).

Sometimes I use RETURN to exit from a program and do more or less what you're trying to do.
