Set Up Parameter For Selecting Shared Memory Extended Function - Mitsubishi Electric MELFA BFP-A8787-F Instruction Manual

2Preparation for Using Extended Function

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."
Parameter
Select shared
memory extended
function
To use the shared memory extended functions and sequencer direct performance functions, set each bit as
follows:
Use the shared memory extended function
Use the sequencer direct performance function
When using the sequencer direct performance function, robot's internal memory is extended as follows:
Robot controller's internal memory
Sequencer direct performance is invalid:
Extend and delete

Set either bit 0, 1 of
parameter IQMEM to 0
System state
Set both bits 0, 1 of

parameter IQMEM to 1
Set either bit 0, 1 of
parameter IQMEM to 0
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.
Description
Set validity (1)/ invalidity (0) for the function.
Sets each bit by allocating a function to each bit.
