Hi everyone.
There some controllers developed exclusive to some clients that supress mode T2. If you are working with one of that and you following all the security rules why don't you use EXT(Automatic External) mode??
If needed reduce $OV_PRO by forcing this in submit(SPS).
This would be a highly unsafe way to operate. T2 is generally intended to allow the operator to be close to the robot while allowing full-speed motion, but still protected by the teach pendant enabler (dead-man switch). Trying to do the same thing with EXT would remove the enabler safety, and also put the start/stop of the program under control of external devices, rather than the KCP.
Controlling $OV_PRO from the SPS is effective, but should
not ever be considered to be "safe" -- for one thing, the SPS can easily be stopped but the robot can still operate. It's not something to wager life or limb upon.
