Type System parameter (read-only)
Syntax PLC_STATUS(mode)
Description The PLC_STATUS(0) system parameter contains the monitored PLC
CPU/PC21 bus status. The status consists of status bits, which defini-
tions are shown in the table below.
Bit number Description
8 PLC Program Mode flag
9 FALS (Severe Failure) PLC flag
10 FAL (Non-severe Failure) PLC flag
11 LOAD OFF PLC flag
12 Axes watchdog enable monitor. See word n, bit 1 3-3-1-1.
14 Output enable monitor. See word n, bit 3 3-3-1-1.
PLC_STATUS(1) returns the elapsed time in milliseconds since the last
PLC cyclic service. This function allows you to monitor the PLC CPU
using a shorter time than the default of 11 seconds.
Arguments • mode
0 or 1, to return the status or the elapsed time since the last PLC
cyclic service.
Example No example.

Type Task parameter (read-only)
Syntax PMOVE
Description The PMOVE parameter contains the status of the task buffers. The
parameter returns TRUE if the task buffers are occupied, and FALSE if
they are empty.
When the task executes a movement command, the task loads the
movement information into the task move buffers. The buffers can hold
one movement instruction for any group of axes.
PMOVE will be set to
TRUE when loading of the buffers has been completed. When the next
servo interrupt occurs, the motion generator loads the movement into
the next move (
NTYPE ) buffer of the required axes if they are available.
When this second transfer has been completed, PMOVE is cleared to 0
until another move is executed in the task.
Each task has its own
PMOVE parameter. Use the PROC modifier to
access the parameter for a certain task. Without PROC the current task
will be assumed.
Arguments N/A
Example No example.
