Dave, Chris
Thanks for the tip about the watch window - that will be useful.
I have found a work around - I add a small value to the result so that the
timer value is never set to zero. That has solved the problem.
%TM0.P = 16*(%IW1 - %IW0) + 1
and has no significant effect on the functioning of the toolchanger. It now
works fine and one can select any one of 6 tools (btw it is a EMCO Compact 5
CNC toolchanger, if anybody is interested.
