2.1.3 Set up Parameter for Selecting Shared Memory Extended Function
The parameter "IQMEM" for selecting the shared memory extended function is 16bit data. Set the bit 0 to
one to use the extended functions (monitoring, operation functions). Set the bit 1 to one to use the
sequencer direct performance function. Both bits can be set to one.
For information on how to set up a parameter, refer to Supplement volume "Instruction Manual, Detailed
Description of Functions and Operations."
To use the shared memory extended functions and sequencer direct performance functions, set each bit as
follows:
When using the sequencer direct performance function, robot's internal memory is extended as follows:
When the sequencer direct performance function is valid, external program variable
and system state variable areas are extended in the robot controller (extended vari-
ables). When the function gets invalid, the extended variable area is cleared. Conse-
quently, after the sequencer direct performance function was enabled once, the
robot location was taught, and the data was set, when the parameter is turned back,
be aware that the previous teaching and setting data will disappear.
