DASA110 ABB Intelligent spare parts module of control card

Description

■ The life estimation of an unused battery of DASA110 at “room temperature” (25 ° C or 77 ° F) (called “shelf
Life “) is 5 years
■ If a continuously used battery (which provides a current loop for the memory when the PLC is powered off) is expected to
The service life is as follows:
Estimated average life of templates at room temperature
CPU template 311, 313 and 323 2 years
CPU template 331-364 1 years
CPU374 January

■ The battery does not work when the PLC is powered on, so the frequency of power failure of DASA110 directly affects the service life of the battery,
Some users will keep the PLC powered on, and others will power off the PLC every night
■ Temperature is a very important factor affecting the service life of the battery, which is above room temperature (25 ℃ or 77 ℃)
The service life of the battery will be slightly shortened if the temperature is below zero (0 ℃ or 32 ℃)
■ The type of CPU will also slightly affect the battery life. Some CPUs have more memory than others
Type requires more power, and some CPU sometimes clock while others do not. More storage requires more
A clock also needs battery current to maintain its operation
Low battery alarm mode
There are three basic PLC low power alarm modes:
■ When the power is low, the “BATT” light on the power supply template turns red. The disadvantage of this method is that PLC is usually installed in the
In the cabinet, the lamp is not easy to see
■ PLC fault table will update low power alarm information, DASA110 needs a programmer connected to PLC to view PLC fault table
■ Some specific system flags change to 1 when the power is low, including% SA011 (LOW_BAT),
%SC009 (ANY_FLT),% S010 (SY_FLT) and% SC012 (SY_PRES)
%SA011 (LOW_BAT), this bit can be used as a node in ladder program, and an input can be connected
To control an alarm light on the operation panel (as shown in the following example) or send an alarm message to the operator
Terminal interface
%SA011 %Qxxx
In the above line, when the PLC finds that the battery is low,% SA011 will be closed, which will connect the output coil of% Q
The address can be used as the output of the template to make an alarm light light. Another method is to turn this coil (of course, it can also be
The status of one% M coil) is transmitted to the HMI terminal through communication, such as GE Fanuc CIMPLICITY
HMI unit, DASA110 When this special bit changes to 1, HMI can be displayed as alarm information, and more relevant system marks
Refer to GFK-0467K Series 90-30/20/Micro PLC CPU Marker Setting Manual for instructions on bit and ladder programming
