CP435-T-ETH ABB Intelligent spare parts module of control card

Description

■ CP435-T-ETH serial communication port is compatible with RS-485 and uses GE Faunc SNP protocol (90 series protocol), 90-30
SNP is used as the default protocol for all CPU serial ports of the series. The 350-364 CPU firmware uses version 9.00,
The 311-341 CPU firmware uses version 8.20. Please refer to page 5-13 for details

■ The serial port connector of CP435-T-ETH installed in the power supply template in the CPU base plate only has the serial port connection function, which is installed in the expansion or remote
The serial port in the power module in the process base plate does not have the serial port connection function
■ Any device connected to the serial port requires a+5V DC power supply, which is composed of a series of 90-30 power modules
The maximum power consumption must be calculated here (see Chapter 12 titled “Power Template Capacity
Quantity calculation)
■ All series 90-30 CPUs are equipped with serial ports. 351, 352 and 363 CPUs also have additional serial ports
This will be explained in the following chapters
watch out
During the connection of this serial port, attention must be paid to the specification requirements for common mode voltage
Modal conditions cause transmission errors and/or damage to the Series 90 PLC components. Specify
See Appendix A. GE Fanuc must be used when the common mode conditions specified in the specification are exceeded
IC690ACC903 is used to isolate the serial port. See Appendix G for the description of serial port isolation
Volatility of memory
Volatility means that when the power supply is cut off, the content (data) in a specific memory can be retained or lost
■ Volatile memory – When the power supply is cut off, the contents of the memory will be lost. Data in RAM memory will be lost
Therefore, in order to prevent data loss in RAM when the PLC is powered off, a backup battery must be used
■ Non volatile memory — When the power supply is cut off, the contents of CP435-T-ETH memory will be retained. Various types of PROMs (available
Program Read Only Memory)
RAM memory
Each type of series 90-30 CPU uses RAM memory for its “working data storage”, and the RAM chip
CMOS type is used. CMOS RAM is a Comprehensive Metal Oxide Semiconductor Random
Access Memory only takes its initials. CMOS RAM has relevant fast or slow storage capacity, which can
It is easy to read or write data
In the embedded CPU template, RAM memory is installed in the backplane circuit board. In the pluggable CPU, RAM memory
The processor is installed in the CPU template. The function of the backup battery is usually to retain the data in RAM after the power is cut off
Not lost
RAM memory backup/battery backup information
