MODULE
9.2.4 Operating SRAM monitor screen
(1) Precautions for SRAM monitor screen
The SRAM monitor screen is updated by acquiring the data of only the display area
from the battery-backed-up RAM of the C Controller module when the
button is clicked.
(2) SRAM monitor screen
Monitors the battery-backed-up RAM and changes and saves the data.
Remark
The battery-backed-up RAM data entered or cleared from the SRAM monitor can
be accessed by the QBF_ReadSRAM function or QBF_WriteSRAM function.
Section 10.2.1
Danger
When performing the control (data change) of an operating C
Controller module connected to a development environment
(personal computer), configure an interlock circuit in the user
program so that the whole system will always operate safely.
When performing the other control (operating status change (status
control)) of the operating C Controller module or when operating the
development environment (personal computer), configure an
interlock circuit in the user program so that the whole system will
always operate safely.
Especially in the above control performed for a remote C Controller
module from an external device, a problem on the C Controller
module side may not be solved immediately due to a data
communication error.
Configure an interlock circuit in the user program, and also set up
measures as a system in case of data communication errors
between the external device and C Controller module.
