PMAC NC/Turbo Clipper: SKIP position update

I have PMAC NC PRO2 and Turbo Clipper Combo (PMAC2). Am trying to install Renishaw probe on the system. I am noticing that I cannot read in commanded work coordinates positions (#5041, #5042, #5043) or current work coordinate skip positions (#5061, #5062, #5063) until we execute M30 or end the program. I need these positions to be updated in real time as soon as the SKIP is triggered for the probe to work. The SKIP signals for X, Y and Z axes are hard-wired to USER Input on JMACH2 Port. G31 seems to be working - it is just the update part I am struggling with.

Below is the code I am using to test and monitoring values on Data Pages for Common Variable on PMAC NC PRO2 HMI.

...... any ideas?
