Paramacros
Chapter 20
20-44
The macro parameters are separated into 4 tables that are accessed
through softkeys. Table 20.I lists these softkeys, the parameters
accessed through them, and additional information on the parameters.
Table 20.I
Macro Parameter Tables
Softkey: Used to:
{LOCAL PARAM} View the local parameters of the currently active program (unless the block
look ahead has scanned an upcoming paramacro call). This table includes
parameters numbered 1 - 33. Only one of the five available sets can be
viewed on this screen at any one time. The local parameters reset to zero
at the end of program command (M02 or M30).
{COM-1 PARAM} View or edit the common parameters (available to any program,
subprogram, or paramacro program) numbered 100 - 199. These common
parameters lose their value and are reset to zero when power to the control
is turned off.
{COM-2A PARAM} View or edit the common parameters (available to any program,
subprogram, or paramacro program) numbered 500 - 519. These common
parameters are battery backed up on the 9/240; on the 9/260 and 9/290,
they are backed up by the supercapacitor. Their value is retained even
when power to the control is cycled off. In addition to being battery backed
up, these parameters allow an alphanumeric name to be assigned to them.
This alphanumeric name is only for the purpose of easy identification. It
cannot be used to call a common parameter in a program.
{COM-2B PARAM} Use this softkey to view or edit the common parameters. These common
parameters, 520 to 699, are battery-backed up on the 9/240. On the 9/230,
9/260, and 9/290, parameters 520 to 999 are backed up by the
supercapacitor. Their value is retained even when power to the control is
cycled off. They differ from common 2A parameters in that they do not
allow an additional name to be stored in the table with their values.
2. Press the appropriate softkey for the table to be viewed or edited.

If viewing the local parameter table, do not continue to step 3. If
editing one of the common parameter tables, move on to step 3.
3. Select the parameter to change by moving the cursor to the desired
parameter number. The selected parameter appears in reverse video.
