D2D146-AA28-28 ABB The control power board card of axial flow fan is available for after-sales

Description

D2D146-AA28-28 developed programs stored in series 90-30 311-341 CPUs are automatically converted to use through program software
In the PLC of the 350-374 CPU, the created or developed programs stored in the 350-374 CPU can also be automatically converted
It is converted into PLC using 311-341 CPU. However, it should be noted that some CPU support features, such as floating point type
The D2D146-AA28-28 is not supported by other CPUs, such as large computation or data storage. In this case, try to download the D2D146-AA28-28 to the unsupported
Errors will be reported in the CPU of one or more programs or hardware configuration features. However, in this case, edit and modify
It is possible to configure the program or hardware to suit the target CPU

Accuracy of CPU time and date (TOD) table
Within the ambient temperature range of 0-60 ° C, the accuracy of time and date of series 90-30 is 9 seconds per day
Its accuracy has a relative stability at any temperature. In order to meet the application of high accuracy
Some suggested methods are as follows:
■ In order to make the CPU stable under various ambient temperatures, it is necessary to measure the time in a 24-hour time cycle
And then set a periodic increase or decrease time of “correction” coefficient in ladder diagram to maintain
Accuracy of CPU time. In this case, the instructions are # 7 Service Request t, “When changing/reading time date
Clock “. At an appropriate time, the service request will access the time, date and clock, and an incremental instruction will be added in the correction
And another service request t will write the new value into the time date clock
One disadvantage is that if a CPU is replaced, a new correction factor will have to be measured, and the ambient temperature will change
It also affects the modification of this method. Therefore, the success of this method requires that the CPU be placed in a stable
In the surrounding environment
■ D2D146-AA28-28 If higher accuracy is required, PLC needs to use radio connection or global satellite positioning with a third-party manufacturer
System interface
Breakfree SNP protocol
Breakfree SNP is the default protocol in all series 90-30 CPUs, starting from the firmware version 9.00 of 350-364 CPUs
This and Model 311-341 CPU 8.20 firmware versions. The Breakfree feature makes the protocol compatible with a variety of modems, which
The characteristics are the same as those of the existing SNP master control unit, such as the computer running PLC program software or the programmable coprocessor (PCM) module
The boards are compatible and consistent. In most applications, multiple network communications and short scanning time are required
The execution capability may want to lose the Breakfree SNP function. Breakfree SNP can be configured as disabled or re enabled. through
Communication requirements are described in Series 90 PLC Serial Communication User Manual, GFK-0582
350 – 374 CPU
The Model 350 – 374 series CPU is designed to meet the needs of customers with the increase of storage capacity, fast processing speed and
Functions not available in CPU, CPU developed to meet user requirements
Compatibility between hand-held programmer and memory card
■ Series 90-30 handheld programmer (IC693PRG300) used in CPU 350-374 models cannot be viewed or edited
For user programs, the GE Fanuc program package must be used to create or edit user programs for 350-374 CPUs
■ Series 90 memory card (for handheld programmer) does not support 350-374 CPU
■ The hand-held programmer program mode only supports the write and read operations from the CPU flash memory
■ Although the configuration mode of the handheld programmer can be used to configure basic hardware in this type of CPU, it cannot handle the following problems:
The configuration of D2D146-AA28-28 and embedded Ethernet interface in CPU 364/374
■ The hand-held programmer can be used to change the time, date and clock unless the configuration parameter of write protection function is set to enable and enable
The switch is turned OFF in the ON (protection) state
■ The hand-held programmer can be used to edit the value in the% R register
■ The hand-held programmer can call or clear the contents of the 350-364 CPU
■ CPU374 does not support hand-held programmers
