Name
Designate whether the user program (AUTOEXEC.OBJ) is automatically
transferred from the card to PC memory when the power is turned ON. DIP
switch pin #5 on the CPU can be turned ON to transfer both the user
program (AUTOEXEC.OBJ) and the PC setup (AUTOEXEC.STD). Refer to
information on the Memory Card for details.
(Default: Don’t transfer)
Designate the I/O refresh method as cyclic, zero-cross, scheduled, or
immediate.
Cyclic refreshing will occur once each cycle at the end for user program
execution.
Zero-cross refreshes are synchronized with the times the voltage of the
commercial power supply is 0 V. Set this method to more accurately turn off
outputs when using AC power supplies.
Scheduled refreshed occur at a specific timer interval. The scheduled
refresh interval must also be set. Set the execution interval between 10 and
120 ms. Fixed interval refresh is effective only when the program execution
CPU is not synchronized with the communications CPU.
Immediate refreshing is also possible using certain instructions from the user
program. To refresh using only these instructions, set scheduled refreshes
and then set the refresh interval to 00 ms. If this is done, I/O status will be
refreshed only when instruction in the user program call for it.
This setting is effective immediately.
(Default: Cyclic)
Designate whether battery errors are detected. This setting is effective
immediately.
(Default: Detect)
The following bits will be turned ON when a battery error is detected.
A40204 Battery Low Flag (PC or memory card)
A42614 Memory Card Battery Low Flag
A42615 PC Battery Low Flag
Designate whether a momentary power interruption is treated as an error. If
momentary power interrupts are treated as errors, they will be recorded in
the error log (see setting F). This setting is effective immediately.
(Default: Non-fatal)
Designate whether the CPU is placed on standby during initialization and
until SYSMAC BUS/2 terminators are properly detected.
(Default: CPU waits)
Designate whether or not the time between CPU-bus Unit services is to be
measured. If measured, the cycle is stored starting at A310. This setting is
effective immediately.
(Default: Don’t measure cycle)
